INTRODUCTION
A.

The Boundary and Annexation Survey

The U.S. Census Bureau (Census Bureau) conducts an annual survey called the Boundary and
Annexation Survey (BAS) to collect information about selected legally defined geographic areas,
such as counties (and equivalent areas), incorporated places, minor civil divisions (MCDs),
federally recognized American Indian Areas (AIAs), including reservations, off-reservation trust
lands and tribal subdivisions, Hawaiian Homelands, and Alaska Native Regional Corporations
(ANRC). BAS also provides an opportunity for participants to review the names and geographic
relationships for these areas. Title 13, U.S.C., Section 6, authorizes this survey.
The Census Bureau uses the boundary information collected during the BAS to tabulate data for
the decennial and economic censuses, and to support the Population Estimates Program (PEP)
and the American Community Survey (ACS). Maintaining correct boundaries and boundary-tofeature relationships through the BAS helps ensure that the Census Bureau assigns the
appropriate population to each governmental unit (GU).
In compliance with the Office of Management and Budget Circular A-16, the BAS supports the
Census Bureau’s spatial data steward responsibilities for the Federal Geographic Data
Committee (FGDC) and the Geospatial One-Stop by updating the inventory and boundaries of
GUs.
In addition, the BAS is the source of up-to-date information on changes to the boundaries,
codes and names of incorporated places, MCDs, counties (and equivalent areas), Hawaiian
Homelands, ANRC, and federally recognized AIAs, which include reservations and offreservation trust lands used by the U.S. Geological Survey’s (USGS), the National Map, and the
Geographic Names Information System (GNIS).
Please visit the BAS program Web site at . For more information on the BAS, please view the “Introduction to BAS”
video series on the Census Bureau’s BAS Web site at

What’s New for the 2018 BAS?
The Geographic Partnership Support Desk (GPSD) is now fully functional and available to assist
with any questions respondents may have regarding BAS.
Redistricting data contacts participating in the Voting District Project (VTD) may submit boundary
updates for reconciliation with BAS contacts.

Key Dates for BAS Respondents

January 1, 2018 — All boundary changes must be legally in effect on or before this date to be
reported in the 2018 BAS.
March 1, 2018 — BAS submission date deadline for boundary updates to be reflected in the
ACS and PEP published data. Boundary submissions received by this date are also reflected in
next year’s BAS materials.
May 31, 2018 — BAS boundary updates submitted by this date will be reflected in next year’s
BAS materials.

PART 1: DIGITAL BAS REQUIREMENTS
1.1

Digital BAS Participation Requirements
All participants must have the ability to edit a Census Bureau shapefile. The Census Bureau
requires that entities update Census Bureau shapefiles with boundary and feature changes,
rather than submitting a shapefile from a local Geographic Information System (GIS).
All participants must provide current information for the BAS point of contact, the person
updating the shapefiles, and the highest elected official (HEO) for the entity.
All participants must provide legal documentation numbers and effective dates for all legal
boundary changes (annexations and deannexations).
Each non-legal boundary correction must contain proper update documentation according to
boundary correction guidelines listed below, or the Census Bureau will not make the correction
for this BAS cycle.

All participants must use the SWIM to submit their changes to the Census Bureau. Due to
security requirements, we cannot accept submissions via FTP, email or any protocol other than
the SWIM site (). If you indicated on your Annual Response
Form that you wished to receive the GUPS application, you will automatically receive the SWIM
URL and a registration token via email. The email should arrive 5 days after the Annual
Response is completed online (or 5 business days after the Census Bureau receives the paper
form). To access the SWIM, enter the following URL in a new browser window:
.

1.2

BAS Informational and Tutorial Videos

The Census Bureau created training videos to give BAS participants detailed instructions and
information on how to report and submit BAS changes. These videos are available on the BAS
Web site at: .
If there are any questions or concerns about the participation requirements, contact the Census
Bureau at 1-800-972-5651 or [email protected].

PART 2: TOPOLOGICAL RELATIONSHIPS AND SPATIAL
ACCURACY
The Geography Division of the Census Bureau is responsible for developing geographic
applications and executing related activities needed to support the Census Bureau in collecting
and disseminating census data. For more than twenty years, the Census Bureau’s Master
Address File and Topologically Integrated Geographic Encoding and Reference (MAF/TIGER)
System has been a critical resource for supporting the Census Bureau Geographic Partnership
Programs.
The following section will describe how the Census Bureau uses a topologically integrated
system and how this differs from traditional GIS, which use separate layers of data.

Topological Relationships in MAF/TIGER
At the Census Bureau, we describe topology as the relationship between different levels of
geography. MAF/TIGER is a geographic database in which the topological structures define the
location, connection, and relationships of streets, rivers, railroads, and other features. These
topological structures help define the geographic entities for which the Census Bureau tabulates
data.
Instead of having a separate layer for each feature class (roads, boundaries, etc.) all
MAF/TIGER information is stored in one layer or file. See Figure 1 and Figure 2 for samples of
topologically integrated files in MAF/TIGER.

Figure 1. Road Representing 3 Types of Boundaries

This example shows how a road in MAF/TIGER can also represent
a block boundary, place boundary and a school district boundary.

Boundary and Annexation Survey Respondent Guide: Digital

Page 7

Figure 2. Typological Integration of Four Classes

This example shows the topological integration of four different
feature classes into one layer. One road feature represents not
only a road, but also a block boundary, place boundary, and a
school district boundary.

GIS and Spatial Accuracy
In a GIS, feature classes are often not topologically integrated: they are separated into
individual layers. When you overlay these layers in a GIS, there may be boundary
misalignments due to the nature of the data. These non-topologically integrated layers could
cause issues in MAF/TIGER. Figure 3 and Figure 4 show how files that are not topologically
integrated might appear in a GIS when overlaid.

Boundary and Annexation Survey Respondent Guide: Digital

Page 8

Figure 3. Overlay of Four Feature Classes

This example shows an overlay of four different feature classes.
Notice how the topological relationship is compromised. The block,
place, and school district boundaries, which are supposed to follow
the road feature, are no longer aligned with the road in several
locations.

Figure 4. GIS Place Boundary Does Not Follow Road Feature

This example shows a situation where a local GIS place boundary
does not follow a road feature. Assuming that the boundary follows
the road feature, changing the Census Bureau place boundary to
match the local file exactly and become misaligned (see arrows)
would dissolve the topological relationship in MAF/TIGER.
Boundary and Annexation Survey Respondent Guide: Digital

Page 9

The spatial differences between local GIS data and the Census Bureau’s topologically
integrated file are often very small (less than ten feet) and can create boundary-to-feature
relationship issues for the Census Bureau. Part 5: Updating the Census Bureau Shapefiles,
Section 5.12 provides instructions on how to review digital submissions for small spatial
boundary corrections. It also lists some of the potential consequences of making spatial
boundary corrections that dissolve the topological relationships present in MAF/TIGER.
You may find examples of suggested methods for correctly making boundary changes in
Appendix B and Appendix C.

Census Bureau Topology Training Video
The Census Bureau created a video on the subject of topology and why topology is important to
the BAS. For more information, please go to
where you can watch the video.

order to review your boundaries and submit changes.
The Census Bureau provides entity layers in ESRI shapefile format for download via the BAS
Web site. Regardless of the number of geographic entity polygon based shapefiles each
participant downloads and edits, there is only one shapefile for the linear feature network for
each county. See Table 1 for the names of the shapefiles.

PART 4: CENSUS BUREAU GEOCODING
Geocoding is how the Census Bureau codes population to geographic entities. There are two
primary methods of geocoding used by the Census Bureau. Both of these involve coding an
address to a spatial polygon, but one uses Global Positioning System (GPS) technology, while
the other uses address ranges.

4.1

MAF Structure Point Geocoding

A field worker stands in front of a house or living quarters, and records the physical location with
a GPS device (Figure 5). Usually, the GPS point should fall very close to the front door of the
house. However, since GPS points were collected in the field, real-world obstacles like locked
fences, poor satellite reception, or even aggressive dogs might sometimes prevent the worker
from gaining access to the front door. In these circumstances, the worker may have to take the
GPS coordinate from the sidewalk or side of the road.

Figure 5. MSP Method of Geocoding

MAF Structure Point (MSP) method of geocoding. Notice that it is
occasionally not possible for the field worker to go all the way to the
front door, due to unforeseen circumstances, like the fence or the
dog shown above. Thus, the MSP (represented here by the red
pins) can sometimes fall within the road or the road right-of-way.

Boundary and Annexation Survey Respondent Guide: Digital

Page 12

4.2

Address Range Geocoding

When no MSP is available, the Census Bureau codes houses and living quarters according to a
potential range of addresses associated with the adjacent stretch of road (Figure 6).

Figure 6. Address Range Method of Geocoding

When it is not possible to collect an MSP, houses are geocoded
according to their placement along a range of potential addresses
along that road. Since the address has a relationship with the road,
boundaries placed on front lot lines will lead to mis-geocoding
unless an offset flag is used.
While the two methods of geocoding differ greatly, both rely heavily on the integrated nature of
MAF/TIGER. These geocoding methods are affected by the way streets and boundaries are
represented in relation to one another. This interdependence between streets, boundaries, and
geocoding means that Census Bureau representations of legal boundaries may sometimes
differ from other representations (e.g., in local or state GIS). This is especially true regarding
geographic corridors and offsets that follow road right of ways (or the front lot lines of parcels).
In both of the examples above, delineating a boundary along the front lot line will tend to
increase the risk of incorrect geocoding. As a result, using the road centerline as a boundary is
the safer method.

When completing a BAS submission in which a road or road right-of-way is owned or
maintained by a place but the adjacent housing is not, the respondent should use the
centerline of the road (not the front lot-line) as the boundary whenever possible. If local
or state law requires the use of the front lot line boundary, the respondent must explicitly
designate the polygon(s) between the road centerline and the front-lot boundary as a
corridor or an offset (see Section 5.4 and Section 5.5 of this document for more
details).
Boundary and Annexation Survey Respondent Guide: Digital

Page 13

PART 5: UPDATING THE CENSUS BUREAU SHAPEFILES
Census Bureau shapefiles can be updated to reflect boundary and/or linear feature changes
that have occurred since the last BAS update. Please go to Appendix B and Appendix C and
watch the Digital BAS demonstration video series at for more examples.
Note: If there are problems with the processing of returned files, the Census Bureau will email a
feedback document requesting clarification of any issues. If the problem cannot be resolved before
the project deadline, the changes in question will not be made during the current BAS.

5.1

General File Setup Guidelines

After downloading the shapefiles from the PVS download page, follow these procedures before
beginning actual updates:
•
•
•

5.2

Open the downloaded .ZIP file to verify its contents.
Copy the shapefiles into a directory on a server/hard drive.
Open the shapefiles with GIS software.

Changing the Map Projection

Census Bureau files are in GCS NAD83 format and can be projected into any local coordinate
system/projection. Most GIS software packages will allow users to transform file coordinate
systems and projections. For example, if using ArcView to update files, activate and utilize
ArcView’s Projection Utility Wizard extension. If using ArcGIS, use its Project tool in
ArcToolbox. MAF/TIGER shapefile extracts contain defined projection information in the *.prj
file. ArcView and ArcGIS access the *.prj file for projection information so there is no need to
define these parameters before changing the file coordinate systems.
When updates are complete, participants may submit the boundary shapefile using any local
coordinate system/projection if the shapefile contains a .prj file or spatial reference materials
such as metadata.

5.3

Boundary Changes

In order to update MAF/TIGER, participants must create a separate change polygon layer for
each updated entity type (county, MCD, place). Please create change polygons in relation to the
current MAF/TIGER boundary.

Appendix B and Appendix C provide two examples for creating annexation,
deannexation, boundary correction, new incorporation, geographic corridor, and
geographic offset change polygons. Review any boundary change polygons before
submitting them (Section 5.8).
If you need additional shapefiles, please contact the Census Bureau at 1-800-972-5651 or
[email protected].

5.4

Annexations and Deannexations

The Census Bureau will accept annexations and deannexations from counties, MCDs, and
incorporated places. Each annexation or deannexation change polygon must have the required
attributes and corresponding change type populated, as seen in Table 2. The Census Bureau
will snap any annexation or deannexation to a MAF/TIGER feature when it exists within thirty
feet of that feature.
Note: Enter the name of the jurisdiction annexing or deannexing the area in the NAME field.

Boundary Corrections

The Census Bureau will also accept specific boundary corrections from counties, MCDs, and
incorporated places. As with annexations and deannexations, the participant must create
individual change polygons for each boundary correction. Each boundary correction must also
have the required attributes and corresponding change type populated, as seen in Table 3, or
the Census Bureau will reject them.
Note: Enter the name of the jurisdiction the boundary correction is for in the NAME field.

The Census Bureau uses a topologically integrated database. As a result, the Census Bureau
cannot process all types of boundary corrections for inclusion in MAF/TIGER. The following are
types of boundary corrections that the Census Bureau will accept, process, and update or reject
during the current BAS.

Boundary and Annexation Survey Respondent Guide: Digital

Page 15

The Census Bureau will accept and process properly documented boundary corrections during
the current BAS cycle that spatially interact with (abut) other BAS legal changes (annexation,
deannexation, corridor, offset) and meet both of the following two conditions:
•
•

In situations where the existing boundary has been digitized incorrectly or appears in the incorrect
location due to Census Bureau activities; and
Where the overall shape of the geographic entity is maintained and no feature-to-boundary
relationships are dissolved.

The Census Bureau will reject boundary corrections:
•
•

•
•

•

Along county boundaries unless there is a written agreement between the two counties that
documents the correct location of the boundary;
Between adjacent incorporated places or adjacent MCDs unless the county submitting the
changes is part of a consolidated county agreement or there is a written agreement between the
two incorporated places or MCDs;
That dissolves boundary-to-feature relationships (roads, rivers, railroads, etc.) if the difference is
less than thirty feet;
Which are greater than one square mile, or not contiguous with the rest of the entity boundary.
These boundary corrections may be part of annexations that were never reported to the Census
Bureau. If they are previously unreported boundary changes, please include effective dates and
legal documentation numbers for these changes; and
That have a width of less than thirty feet over the entire polygon.

Note: Remember that the Census Bureau will snap any entity boundary correction to a MAF/TIGER
feature when it exists within thirty feet of that feature.

New Incorporations

County participants may submit new incorporations for incorporated places and MCDs through
Digital BAS. As with other change types, an individual change polygon must be created for each
new incorporation and possess the required attributes and the corresponding change type field
must be populated (see Table 4).
Note: Enter the name of the new jurisdiction in the NAME field. For required documentation for new
incorporations, contact the Census Bureau at 1-800-972-5651 or [email protected].

Geographic Corridors

The Census Bureau geocodes addresses based on the street centerline. If the geocoding of
these addresses would result in the assignment of population to the incorrect geographic entity,
participants should create a geographic corridor.
A geographic corridor is an area that includes only the road right-of-way and does not contain
any structures addressed to either side of the street. Figure 7 shows a corridor created where
the incorporated place owns the right-of-way but the housing units are not included in the
incorporated place (shown in color).
Figure 8 shows that the right-of-way belongs in the unincorporated area, while the housing units
are included in the incorporated place (shown in color). This is important for some cities
because they are portraying that the city is not responsible for road maintenance. This is not
relevant for Census Bureau tabulations and is not easy to depict in the MAF/TIGER. This type of
corridor should not be included in a BAS response.

Figure 7. Geographic Corridor Created
Figure 8. Geographic Corridor Not Created

The image on the left (Figure 7) shows that a geographic corridor
should be created to allow for proper geocoding of homes. The
image on the right (Figure 8) shows that the geographic corridor
should not be created and features should be snapped to the street
centerline.
The Census Bureau will accept new geographic corridors. Please create individual change
polygons for each new geographic corridor. Each change polygon must have the required
attributes and corresponding change type populated, as seen in Table 6. In the NAME field,
enter the name of the jurisdiction. In the RELATE field, indicate whether the change is adding
IN or taking OUT (removing) the corridor.

Geographic Offsets

A geographic offset is an area claimed by a geographic entity that is only on one side of a road
and does not include structures addressed to that side of the road.
The Census Bureau is aware that many governments base their legal boundaries on cadastral
(parcel-based) right-of-way mapping. The Census Bureau bases their maps on spatial data that
is topologically integrated. This makes the maintenance of geographic offsets inefficient.
Snapping an entity boundary to the centerline wherever applicable will help to establish more
accurate population counts. If a boundary is the front lot line, the Census Bureau strongly
prefers that the boundary be snapped to the road. If a boundary is at the rear of a lot, then
please depict it as such. Figure 9 depicts a cadastral (parcel-based) boundary map and
Figure 10 shows how the boundary should be reported when sent to the Census Bureau.

Figure 9. Cadastral Data
Figure 10. Same Data Edited to Census Requirements

On the left in Figure 9 is an example of cadastral data. Figure 10
on the right, is the same area shown edited to conform to census
requirements.

The Census Bureau will accept new geographic offsets. Please create individual change
polygons for each new geographic offset. Each change polygon must have the required
attributes and corresponding change type populated, as seen in Table 7. In the NAME field,
enter the name of the jurisdiction. In the RELATE field, indicate whether the change is adding
IN or taking OUT (removing) the area represented as an offset.

The Census Bureau has included an “offset” shapefile in the BAS materials
(PVS_yy_v2_offset_.shp), so that your jurisdiction can be checked for any existing
corridors or offsets. While the Census Bureau prefers that you do not create new offsets, (see
above), this information can be helpful in determining if current boundaries are correct.

•

If a road, subdivision, etc. is missing from the Census Bureau’s feature network, add the
feature(s) and provide the name and MTFC;
If a feature that does not exist is in the Census Bureau’s feature network, delete the feature; and
If a feature is in the incorrect location in the Census Bureau’s feature network, delete the feature
and re-add it in the correct location. Only do this if the feature is very far off or in the wrong
position relative to boundaries or other features.

5.10.3 Address Range Updates
The Census Bureau accepts address range data as part of the linear feature update layer. As
with other linear feature updates, address ranges must have the required attributes and
corresponding change type populated. As existing address ranges cannot be shown in our
outgoing shapefiles, we recommend that participants generally only add address ranges to new
features (see Table 9).

Area Landmarks, Hydro Areas, and Point Landmarks

5.11.1

Area Landmark/Hydro Area Updates

The Census Bureau accepts updates to area landmarks and hydro areas in a similar manner to
legal boundary changes. However, area landmarks and hydro areas are not legal entities, so no
documentation or effective dates are required.
In order to submit area landmark and hydro area updates, create a separate change polygon
layer. Updates to area landmarks and hydro areas include:
•
•
•
•

Boundary corrections (adding and removing area);
Creating a new area landmark or hydro area;
Removing an area landmark or hydro area; and
Name changes.

Figure 11. A Boundary Correction to Park A

Each area landmark or hydro area update must have the required attributes and corresponding
change type populated. In the AREAID field, preserve the existing AREAID for the feature (refer
to Table 10).

methods apply for creating change polygons for area landmarks and hydro areas. When adding
new area landmarks or hydro areas, only add the following types of areas:

•
•
•
•
•
•

Water bodies;
Glaciers;
Airports;
Cemeteries;
Golf courses; and

The Census Bureau prioritizes boundary changes to legal areas in order to meet ACS, PEP,
and BAS deadlines. Therefore, there may be delays in incorporating area landmark and
hydrographic area changes to MAF/TIGER. Please do not resubmit any changes that were sent
during the previous year’s BAS. We are working on incorporating those changes, and they will
be reflected in the next year’s BAS materials.

5.11.2

Point Landmark Updates

The Census Bureau accepts updates to point landmarks. Please submit point landmark updates
as a separate point landmark update layer. Updates to point landmarks include:
•
•
•

Adding a new point landmark;
Deleting an existing point landmark; and
Renaming a point landmark.

Each point landmark update must have the required attributes and corresponding change type
populated. In the POINTID field, preserve the existing POINTID for the feature.

Reviewing Changes to the Census Bureau Shapefiles

Please review all changes to ensure that they are intentional and correct. The video series
“Introduction to the Digital BAS” can be found on the Web site at:
. The videos have
information on many of the topics below.

5.12.1

Boundary-to-Feature Relationships

Please review all changes to ensure that the correct boundary-to-feature relationships are being
created or maintained. The Census Bureau is aware that many governments base their legal
boundaries on cadastral (parcel-based) right-of-way mapping; however, the Census Bureau
bases maps on spatial data that is topologically integrated. Therefore, snap boundaries to street
centerlines (or rivers, railroads, etc.) wherever applicable. This will help establish a more
accurate population count for entities.
The following examples show situations where boundary changes should be snapped to
existing linear features. The Census Bureau will snap boundary changes to any linear feature
within thirty feet.

Figure 12. Boundary Corrections Not Snapped to Existing Linear Features

These boundary corrections are not snapped to existing linear
features in MAF/TIGER. Both boundary corrections should be
snapped to centerlines or population may be assigned to incorrect
entities.

Boundary and Annexation Survey Respondent Guide: Digital

Page 24

Figure 13. Annexation Created without Snapping to Centerlines

This is an example of an annexation created without snapping to
existing centerlines in MAF/TIGER. Unless the boundary is
snapped to centerlines, some of the population may be assigned to
an incorrect entity.
The Census Bureau will not accept boundary corrections that dissolve the current relationship
between an existing boundary and linear feature, without specific instruction that the relationship
is incorrect. The Census Bureau will not incorporate any boundary corrections that create thirty
feet or less of gap or overlap between the existing linear feature and boundary into MAF/TIGER.
See below for examples of changes that will not be accepted.

Figure 14. Small Saptial Correction Not Incorporated

Small spatial boundary corrections would dissolve the relationship
with the river. These boundary corrections will not be incorporated
into MAF/TIGER.

Boundary and Annexation Survey Respondent Guide: Digital

Page 25

Figure 15. Small Spatial Correction Not Accepted

Small spatial boundary corrections would dissolve the boundary-tofeature relationship with multiple streets. Incorporating these
changes would affect the population counts for the area. Therefore,
the Census Bureau will not accept these small boundary
corrections.

5.12.2

Large Boundary Corrections

The Census Bureau will not accept large boundary corrections to an entity without the
appropriate legal documentation numbers and effective dates. These large boundary
corrections may be legal boundary changes that occurred in the past and were never reported
to the Census Bureau. Please submit the appropriate legal documentation number and effective
date so that the changes may be incorporated into MAF/TIGER.

Figure 16. Large Boundary Corrections

Without the appropriate documentation, the Census Bureau will not
accept large boundary corrections.

Boundary and Annexation Survey Respondent Guide: Digital

Page 26

Note: There may be a few instances when large boundary corrections need to be made because of
incorrect digitizing or where the boundary appears in the incorrect location due to other Census
Bureau activities.

5.12.3

Including Required Attribute Information

It is important to review each change polygon and confirm that the correct attribute information
is included. Without the correct attribute information, the Census Bureau will be unable to
process and incorporate the changes into MAF/TIGER. See Section 5.3 for the required
attribute information and corresponding change type codes.

5.12.4

Including Appropriate Metadata (Projection Information)

It is important that the appropriate projection information is included. Each update layer
submitted should contain a *.prj file so that the Census Bureau can convert the projection back
to GCS_NAD83. If the GIS being used cannot create a *.prj file, include the projection
information in metadata. This is critical for the Census Bureau to be able to process the file and
incorporate the updates into MAF/TIGER.

5.12.5

Linear Feature Updates

Please review linear feature changes to ensure that they align with the features currently in
MAF/TIGER.
If linear feature changes do not align with current MAF/TIGER linear features, the Census
Bureau may not incorporate the submitted updates.

Figure 17. New Road Features, Not Added to Existing Road
Figure 18. New Road Features, Correctly Added

The image on the left (Figure 18) shows new road features added
to the existing feature network, but not connected to existing road
features. The image on the right (Figure 19) shows the correction
connecting the new roads to the existing road features.

Boundary and Annexation Survey Respondent Guide: Digital

Page 27

5.13

Additional Review Information

The Census Bureau will not make any boundary change that affects adjacent legal entities
without the appropriate documentation. Please review any change polygons that affect adjacent
entities to determine if they are intentional, legal changes.
Note: Census Bureau will snap any annexation, deannexation, or boundary correction to a MAF/TIGER
feature when it exists within thirty feet of that feature. This helps maintain the boundary-to-feature
relationships in MAF/TIGER and will ensure correct housing tabulation counts for entities.

5.13.1

Submitting Digital Data

If a participant is reporting changes to the BAS, the Census Bureau requires that each
participant submit at least one shapefile (change polygons). The total number of layers
submitted depends on what types of changes are reported. The following is a list of change files
that may need to be submitted:
Change Polygon Layers (County, Minor Civil Division, Incorporated Place, and Consolidated
City)
•
•

These layers consist of the changes that the Census Bureau needs to make to entities; and
A layer of change polygons should be created for each level of geography (county, MCD,
place, etc.) that changes are being submitted for.
Whole Modified Entity Layer (County, Minor Civil Division, Incorporated Place, and
Consolidated City)

•

These layers should only contain the complete and current boundary for the entity being
updated; and
• A whole entity layer should be created for each level of geography that change polygons are
being created for.
Local Government Feature Network and Boundary Layers (optional)
•

These layers will help the Census Bureau resolve any questionable change polygons and
establish the correct boundary-to-feature relationships.
Feature Update Layer (only if there are feature (road, river, railroad, etc.) additions, deletions,
name changes, recodes, or address range updates)

• Include a linear feature update layer with only feature segments requiring a correction.
Area/Hydro Landmark Update Layer
•

An area/hydro landmark update layer should be submitted only if there are area and/or hydro
landmark updates.
Point Landmark Update Layer

•

A point area landmark update layer should be submitted only if there are point landmark
updates.
BAS Contact Text File (if the BAS point of contact (the person that receives the BAS Annual
Response Email) has changed);

Compressing the Digital Files

The SWIM requires all BAS returns to be zipped prior to submission. Please compress ALL
update materials (including change polygon shapefiles, whole entity shapefiles, linear feature
updates, landmark updates, local government feature network and boundary layers, and the text
or other file with your updated BAS contact information).
Navigate to the directory with the shapefiles.
Note: Centerline files or any additional information that may be helpful for Census to process your file is
optional. One example where this would be helpful is if a particular polygon was not snapped to a
river or road because the boundary does not follow the river or road.
Select all files and right click on the selection.
Select WinZip, and then Add to Zip file.

Submitting Digital Files via SWIM

The Secure Web Incoming Module (SWIM) is a one-stop location for submitting your geographic
program files to the Census Bureau. The Census Bureau now requires that all BAS participants
use the Census Bureau’s SWIM for submitting update materials.
Do not send your submission as an email attachment, as we cannot accept them due to the
security policy at the Census Bureau.
The Census Bureau will email the BAS contact a SWIM registration token and digital
submission instructions five days after the BAS contact responds to the BAS Annual Response
indicating that they have changes to report. To respond online, please fill out the online form at
. The five-day waiting period
will give the Census Bureau staff time to update the BAS contact record if necessary so that the
email reaches the right person.
Current SWIM Users
If you are a participant in another Census Bureau partnership program, or participated in a previous
BAS year, and already have a SWIM account, you may use your current account to submit files for the
BAS. You do not need to set up a new account.

This token is good for one personal account within the SWIM. Once you have registered for an
account in SWIM, you will no longer need the token to login into the system. If you require
additional individual SWIM accounts within your organization, please contact the Census
Bureau at 1-800-972-5651 or email [email protected]. Moreover, if you are a participant for
other Census Bureau geographic programs, you only need one SWIM account to submit files for
all geographic programs.
At this time, SWIM only accepts ZIP files. Please zip all your update materials (e.g., spatial
updates and other relevant update documents) into one ZIP file for your entity’s submission, and
follow the instructions listed below:
In a web browser, go to .

Additional Information

The Census Bureau recommends using Federal Information Processing Standards (FIPS)
codes to identify entities such as counties, minor civil divisions, and incorporated places. Using
a standard coding scheme facilitates the digital exchange of data.
The Census Bureau includes these codes are in the BAS shapefiles. Online, you can find the
codes at . If there are any questions
or problems, contact the Census Bureau at 1-800-972-5651 or [email protected].
Due to limited staff, the Census Bureau may not be able to make all updates this year. The
Census Bureau will prioritize updates in the following order: legal changes, boundary
corrections, linear feature changes, and landmark changes. The earlier the Census Bureau
receives a submission, the greater the chance that the Census Bureau will be able to make all
of the updates. Only submit changes that occurred on or before January 1, 2018. The Census
Bureau will not be able to make any updates effective after this date until next year’s BAS.

2018 DIGITAL BAS EXAMPLE PROCESS 1
B.1

Required Census Bureau Shapefiles

When downloading shapefiles for the 2018 BAS, shapefiles will begin with the prefix
(e.g., PVS_18_v2_edges_.shp). Throughout this guide, Census Bureau uses the
prefix of bas_2018, but the PVS files are exactly the same.
Copy the data to a hard drive/server, and unzip the data to ensure that the correct data was
downloaded. For an incorporated place, these layers are critical:
•
•

PVS_18_v2_place_.shp
PVS_18_v2_edges_.shp

Note: represents the two-digit state code and three-digit county code.

The shapefiles should include the home county/counties as well as all adjacent counties
(if necessary).
Note: The Census Bureau suggests that participants make an extra copy of the data as an emergency
backup.

B.2

Local Data

The minimum data necessary is a jurisdiction polygon shapefile showing only the outer
boundary or boundaries. Local parcel files are not acceptable for this method. If each
jurisdiction’s boundaries are contiguous, the file should contain only one polygon for each entity;
if some of the entities within the jurisdiction are non-contiguous, they may be saved as a multipart polygon or consist of one polygon for each disjointed part. Other local data layers that may
be helpful if available include centerline data, hydrological, railroad, or other linear feature data,
and imagery.

B.3

Symbolizing Layers in ArcGIS

The following are suggestions for symbolizing Census data in ArcGIS. For the Edges layer,
symbolize the linear features by grouping like MTFCC codes (codes sharing the same first
character). See Table 26.

Symbolize the place layer using Fill Color of RGB (255, 235, 190) with no outline.
Note: County participants with many adjacent incorporated places may want to use different colors to
distinguish one place from another.

B.4

Extracting Incorporated Place or MCD Data from Census
Shapefiles

Note: County participants submitting county boundary changes can skip this step. Use the
PVS_yy_v2_county_ shapefile which only contains the county boundary. Counties
submitting for multiple incorporated places or MCDs skip ahead to Section B.4.3.

Name the shapefile Differences_between_BAS_local, Differences1, or anything easy to
find/remember.

Click OK.

Figure 35. Finalizing the Symmetrical Difference Process

Note: This process creates a layer that contains all of the differences between Census Bureau and local
boundaries. However, the Symmetrical Difference tool creates multipart polygons that need to be
broken up and individually coded.
3. Turn on Editing (using the Editing dropdown in the Editor toolbar). Select all of the records in the
layer that was created in the Symmetrical Difference step.
4. On the Advanced Editing toolbar, click the Explode tool

The new layer shows individual change polygons representing the differences between the
Census Bureau and the local government’s representation of the boundaries. Please review
these differences make sure they are coded appropriately. Continue to the next section for
instructions on reviewing and coding change polygons.

B.7

Reviewing and Attributing Change Polygons

After the individual change polygons have been created, each must be reviewed and
appropriately coded. When reviewing the polygons, please refer to Section 5.3 in the main part
of this guide to look for polygons that should be deleted from your submission, as well as those
that should be snapped to nearby visible features to maintain boundary-to-feature relationships.

B.7.1

Examples

These examples show very small sliver polygons that should be deleted during review as they
eliminate boundary-to-feature relationships with a river (left) and a road (right). Furthermore,
these boundary corrections also are not located near legal changes or corridor/offset changes
(type ‘A’, ‘D’, ‘C’, ‘F’), so they should be removed from consideration.

Renaming and Finalizing Change Polygons

Renaming the shapefile

After creating and coding all change polygons, please rename the change polygon
layer prior to its submission to the Census Bureau. You must complete this
process for each level of geography (county, place, MCD) that has changes.

1. In ArcMap, open the ArcCatalog

tab.

2. In ArcCatalog, navigate to shapefile, right-click and select Rename.
3. Save the output shapefile in the proper naming convention:
bas18__changes_.
Note: You can find the basID numbers on the BAS Annual Response Email or online from this link:
https://www.census.gov/programs-surveys/bas/technical-documentation/code-lists.html
Note: See Section 5.13.5 for instructions on zipping updates.

Submitting the shapefile
The Census Bureau requires participants submit BAS return zip files using the Census
Bureau’s SWIM site. Please submit only the zip file. The SWIM is located at
https://respond.census.gov/swim. For instructions on how to use SWIM, you can find them in
Section 5.13.6 Submitting Digital Files via SWIM of the respondent guide.

Creating and Splitting Linear Features

C.4.1

Creating New Linear features

Some of the linear features needed to create change polygons may not exist in MAF/TIGER. It
may be necessary to create and split lines when forming changes. The existing and newly
created linear features will then be selected to define the boundary changes.
1. In ArcMap, right click the edges layer in the Table of Contents, click Selection, and then click
Make This The Only Selectable Layer, so that the edges layer is the only layer that can be
selected while editing.
2. In the Editor toolbar, click Editor and then click Start Editing.

•

Use P0001 if the feature is a non-visible political boundary.
If the feature is visible, see Appendix D for the appropriate codes.

Note: Each new feature must have an MTFCC code. If larger scale linear feature changes are going to
be submitted, it is best to create those in a separate layer.
Note: Click on Editor and then click Save Edits often so that work is not lost.
3. Once all lines are added, in the Editor toolbar, click Editor and then click Stop Editing (In the
Save window, click Yes.)

C.4.3

Splitting Linear Features

1. In the Editor toolbar, click Editor and then click Start Editing.
2. In the Editor toolbar, click the Edit Tool
button and select a linear feature that needs to be
split. The line will be highlighted when it is selected.
3. In the Editor toolbar, click the Split Tool

button. Click the line where it needs to be split.

The following examples display why it may be necessary to split lines when creating change
polygons.
The desired boundary change is indicated below. When selecting the lines to form the boundary
change, sections of the linear features that are not a part of the boundary update are included

INTRODUCTION
The Boundary and Annexation Survey
The U.S. Census Bureau (Census Bureau) conducts an annual survey called the Boundary and
Annexation Survey (BAS) to collect information about selected legally defined geographic areas,
such as counties (and equivalent areas), incorporated places, minor civil divisions (MCDs),
federally recognized American Indian Areas (AIAs), including reservations, off-reservation trust
lands and tribal subdivisions, Hawaiian Homelands, and Alaska Native Regional Corporations
(ANRC). The BAS also provides an opportunity for participants to review the names and
geographic relationships for these areas. Title 13, U.S.C., Section 6, authorizes this survey.
The Census Bureau uses the boundary information collected during the BAS to tabulate data for
the decennial and economic censuses, and to support the Population Estimates Program (PEP)
and the American Community Survey (ACS). Maintaining correct boundaries and boundary-tofeature relationships through the BAS helps ensure that the Census Bureau assigns the
appropriate population to each governmental unit (GU).
In compliance with the Office of Management and Budget Circular A-16, the BAS supports the
Census Bureau’s spatial data steward responsibilities for the Federal Geographic Data
Committee (FGDC) and the Geospatial One-Stop by updating the inventory and boundaries of
GUs.
In addition, the BAS is the source of up-to-date information on changes to the boundaries,
codes and names of incorporated places, MCDs, counties (and equivalent areas), Hawaiian
Homelands, ANRC, and federally recognized AIAs, which include reservations and offreservation trust lands used by the U.S. Geological Survey’s (USGS), the National Map, and the
Geographic Names Information System (GNIS).
Please visit the BAS program Web site at .
For more information on the BAS, please view the “Introduction to BAS” video series on the
Census Bureau’s BAS Web site at

What’s New for the 2018 BAS?
1. The Geographic Partnership Support Desk (GPSD) is now fully functional and available
to assist with any questions respondents may have regarding BAS.
2. Redistricting data contacts participating in the Voting District Project (VTDP) may submit
boundary updates for reconciliation with BAS contacts.

Key Dates for BAS Respondents
January 1, 2018—All boundary changes must be legally in effect on or before this date to be
reported in the 2018 BAS.
March 1, 2018—BAS submission date deadline for boundary updates to be reflected in the ACS
and PEP published data. Boundary submissions received by this date are also reflected in next
year’s BAS materials.
Boundary and Annexation Survey Respondent Guide: GUPS

Page ix

May 31, 2018—BAS boundary updates submitted by this date will be reflected in next year’s
BAS materials.

BAS State Agreements
The Census Bureau has established a number of agreements with states for reporting boundary
changes. Please visit the BAS State Agreements webpage within the BAS program Web site at
or call
(800) 972-5651 for information regarding state agreements.
Note: The Census Bureau can only establish BAS state agreements for states that require local
governments to report boundary changes to a state agency.

Legal Disputes
If the Census Bureau discovers that an area of land is in dispute between two or more
jurisdictions, the Census Bureau will not make any boundary corrections until the parties come
to a written agreement, or there is a documented final court decision regarding the dispute.
If you have questions concerning this, please contact the Census Bureau Legal Office at
301-763-9844.
For disputes involving tribal areas, the Census Bureau must defer to the Office of the Solicitor at
the Department of the Interior for a legal opinion. Often complicated land issues require an
extended period of time for resolution, and in those cases, the Census Bureau will retain the
current boundary in the database until a legal opinion is issued by the Solicitor’s office.

Respondent Guide Organization
This guide has been created for those who choose to participate in the survey using GUPS.
Those using their own GIS should consult the Boundary and Annexation Survey Respondent
Guide: Digital available on the BAS Web site: . Those using paper maps should
consult the Boundary and Annexation Survey Respondent Guide: Paper. This guide is equipped
with shortcuts to subjects that respondents may want to jump to directly. To move directly to one

section in the diagram includes initial steps. The second section indicates the types of
geographic data that should be reviewed and updated. The final section lists the final steps to
validate and submit changes.

Figure 1. BAS Workflow

Sections 1, 2, and 3 of this guide are organized around the topical areas in the diagram and
provide needed program information and procedures, as well as relevant deadlines.
See Appendix A: BAS Contact Information and Resources for a list of contacts and helpful
program links.

1.1

Receiving the GUPS Application and Shapefiles

GUPS is available for installation two ways. GUPS software is available for download directly
from the BAS Web site . You can also request to receive GUPS software on
DVD, which will be shipped to you in a package containing the GUPS DVD, respondent guide,
and a read me text file.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 1

Once you have installed GUPS on your computer, the BAS shapefiles can be imported from the
BAS Web site directly to the GUPS application. Instructions on how to load data into GUPS
appears in Section 5:: Using GUPS (Basics and Map Management), Error! Reference source
not found.. If you do not have Internet access, you may request shapefiles on DVD. To request
a data DVD, call 1-800-796-3748 or e-mail [email protected].

1.2

Getting Help

1.2.1

GUPS Help

Part 2: How To Use GUPS of this guide contains directions for how to use the tools available
within the GUPS application, as well as step-by-step instructions for how to carry out specific
shapefile updates (e.g., annexations and deannexations, adding and deleting features and
landmarks, etc.).
Embedded within the GUPS application (under the Help tab menu) are other resources,
including a short training video on how to submit a ZIP file through SWIM. Additional videos will
be provided on the BAS Web site as they become available. In addition, a Section 508compliant version of this guide is available there. The Help menu provides a link to both.
For supplemental information on functions within the GUPS that are specific to QGIS, a QGIS
user’s manual can be found at . The
QGIS manual offers particularly helpful information on several activities that are touched on in
this guide, but not described in detail, including working with user-provided data layers, creating
search expressions for attribute tables, and creating customized coordinate systems. For
questions concerning technical problems with the GUPS application, user support is available
via telephone (1-800-972-5651) and e-mail [email protected].

1.3

BAS Help

BAS participants may find the Boundary and Annexation Survey Respondent Guide: Digital
helpful. Although designed for experienced GIS users, it provides important information on
geocoding, topological relationships, and spatial accuracy relevant to Census shapefiles. This
guide can be downloaded at: .
The Census Bureau has also created a number of other BAS-related videos, including a helpful
one on the subject of topology and why topology is important to the BAS. To view these videos,
go to: .

Boundary and Annexation Survey Respondent Guide: GUPS

REVIEWING BAS DATA
The Census Bureau requests that you review and update all legal entities and boundaries within
your jurisdiction, including the new incorporation or disincorporation of legal entities, legal
boundary changes, and boundary corrections. You may also update linear features and
landmarks, including area landmarks, hydrographic areas, and point landmarks, although review
of these is optional.
To help conduct your review, the GUPS application will allow you to import and overlay your
own geospatial data layers with the Census Bureau shapefiles. You can import image files from
web mapping services, geodatabases, and also other file types. Steps to import the most
common types of user-provided data are provided in Section 0:
How to Import User-Provided Data into GUPS.

2.1.

Boundary Corrections

2.2.

Legal Boundary Changes

Legal boundary changes are the result of legal actions (e.g., annexations), and documenting
such changes is the primary goal of the BAS. AIA Legal documentation (e.g., statute, federal
court decision, trust deed) must accompany all AIA legal boundary changes, while legal
boundary change submissions from incorporated places, MCDs, and counties must provide an
authorization number, such as a resolution or ordinance number.

2.3.

Reviewing Legal Boundaries

When reviewing legal boundaries, please examine the Census Bureau shapefiles for all legal
entities in your jurisdiction. These includes:
•

Incorporated places;

•

Minor Civil Divisions (MCDs) such as towns, boroughs, and townships;

•

Counties (and county equivalents); and

•

Consolidated cities.

Requirements for Legal Boundary Changes

2.4.1

Boundary Changes to Legal Entities

For a boundary change to an existing legal entity (or the new incorporation or disincorporation of
a legal entity) to be processed as a legal change, you must provide the legal documentation
number (e.g., law or ordinance number), effective date, and authorization type. You are not
required to submit paperwork documenting the change.
Note: Although additional documentation is not required, we do strongly encourage you to attach
supporting paperwork to your submission (you may do this directly in GUPS). The paperwork will
expedite our ability to reconcile and process any legal updates.

2.4.2

Boundary Changes to Legal Entities in Georgia and Indiana

Georgia: Any legal boundary change made to an incorporated place in the state of Georgia
must include: (1) the effective date, and (2) the acreage of the new entity. In addition, before
entering the change, you must ensure that all annexation/deannexation information has been
reported to the Department of Community Affairs (DCA). The DCA provides the Census Bureau
a list of the entities that reported boundary changes each year. Any legal boundary changes to
incorporated places not on this list will not be placed in the MAF/TIGER System. For additional
information, see: .

Boundary and Annexation Survey Respondent Guide: GUPS

Page 4

Indiana: Per Indiana state law, counties must provide the legal boundary updates for townships.
For more information, refer to Indiana Code 36-6 Government of Townships at
. If you have questions about required
documentation for your particular jurisdiction, contact the Geography Division by phone at
1-800-972-5651 or by e-mail at [email protected].

2.5.

Reviewing Linear Features

It is important that Census Bureau data reflects the most recent linear features to ensure that
new or previously missed housing units located along these features are identified and located.
When reviewing linear features (edges layer) on the Census Bureau shapefiles, first determine
whether any features are missing or need to be deleted. Pay particular attention to areas that
have experienced recent population growth or construction activities, as these are the most
likely to possess new or altered linear features (e.g., new subdivisions, traffic circles converted
to straight ways, or privately maintained roads that serve as public streets, but exclude private
driveways).
You may also add attribute updates (e.g., name, class code, and address ranges) for selected
features. For a complete list of MAF/TIGER Feature Class Codes (MTFCCs), review
Appendix C MTFCC Descriptions.
To aid in the review of linear features, GUPS allows you to import local street centerline files,
hydrography layers, imagery, and other user-provided geospatial data for reference and
comparison against the Census Bureau data.
In your review, please note:
•

S1100 and S1200—If you add road features with an MTFCC of S1100 (Primary Road) or S1200
(Secondary Road), you must supply a feature name. As is the case for all road features, the
feature name should be a proper name or route number.

•

Spatial Inaccuracies—The Census Bureau will not process the wholesale spatial realignment of
features to enhance spatial accuracy. If a feature is in the incorrect location, delete the feature
and add it in the correct location. Take this action only if the feature is exceedingly spatially
inaccurate and/or the current location (with respect to other features and boundaries) affects the
tabulation of housing units to the correct geography, such as legal entities, census tracts, and
census blocks.

•

Address Range Changes—The Census Bureau accepts address range data as part of the linear
feature update layer. As with other linear feature updates, you must supply the required attributes
and corresponding change type for the update. In addition, because existing address ranges are
not shown in our outgoing shapefiles, we recommend that participants only add address ranges
to new features.

2.6.

Reviewing Area Landmarks and Hydrographic Areas

The Census Bureau accepts updates to area landmarks and hydrographic areas in a similar
manner to legal boundary changes. However, area landmarks and hydro areas are not legal
entities, so no documentation or effective dates are required.
Allowable updates for area landmarks and hydrographic areas are:
•

Add new area landmark or hydrographic area;

•

Remove area landmark or hydrographic area;

Boundary and Annexation Survey Respondent Guide: GUPS

Page 5

•

Change or add landmark name; and

•

Boundary corrections (add and remove area).

If you add a new area landmark or hydrographic area, please add only:
•

Water bodies;

•

Glaciers;

•

Airports;

•

Cemeteries;

•

Golf courses; and

•

Parks.

The Census Bureau cannot add other types of area landmark / hydrographic areas to the
MAF/TIGER System at this time (even though others may already exist in the database).
Table 2 shows the acceptable MTFCCs for new area landmarks or hydrographic areas.

Note: If adding an MTFCC K2457 (Airport – Area Representation) area landmark, please limit the
updates to major airports (major regional and international airports). The feature should show the
full extent of the airport facility, that is, do not limit the addition to simply the landing strips.

Area Landmark / Hydro Area Changes May Be Delayed
The Census Bureau prioritizes boundary changes to legal areas to meet ACS, PEP, and BAS
deadlines. Therefore, there may be delays in incorporating area landmark and hydrographic area
changes to the MAF/TIGER System. Please do not resubmit any changes that were sent during the
previous year’s BAS. We are working on incorporating those changes, and they will be reflected in the
next year’s BAS materials.

2.7.

Reviewing Point Landmarks

Because many of the point landmarks contained in the Census Bureau’s MAF/TIGER System
originate from the U.S. Geological Survey’s Geographic Names Information System (GNIS),
which is the official gazetteer of point landmark names for the Federal Government, point
landmark updates are limited in the BAS. The Census Bureau cannot modify any point landmark
imported from the GNIS database. Thus, be aware that name changes or deletions submitted
for the following types of landmarks may be left unchanged:
•

K2451 (Airport or Airfield);

•

K2582 (Cemetery);

•

C3022 (Summit or Pillar); and

•

C3081 (Locale or Populated Place).

Also, due to Title 13 privacy concerns, any landmark with an MTFCC shown in Table 3 below
cannot be added to the MAF/TIGER System as a point landmark. The MAF/TIGER System no
longer maintains any point landmarks with these MTFCCs. Landmarks with these codes could
identify a residence or private business. Thus, it is also important not to add any of the point
landmark types shown in the table using alternative MTFCCs.

QUALITY CONTROL AND FILE SUBMISSION
3.1

Validating Updates

Once you have completed your BAS updates, you must complete a review of your change
polygons to ensure that:
1. The polygons have no unintended holes (e.g., you annexed several faces but missed a traffic
circle or small pond).
2. All boundary corrections meet a minimum size threshold (very small corrections cannot be
processed).
Validate Often
Validation tools in GUPS can be accessed at any time while you are working in the application. We
suggest you utilize them as you work to identify errors early and avoid extensive rework. Steps to use
the Geographic Review tool and the Review Change Polygons tool are included in Section 6.5: How
to Use GUPS Review and Validation Tools.

3.2

Submitting Files Through SWIM

Prompt submission of updates is appreciated. It benefits the Census Bureau—allowing us to
review the files early, provide feedback, and avoid backups in file processing—and you—
guaranteeing your updates are recorded accurately and are reflected in the latest releases of
Census Bureau data products.
For those with Internet access, all BAS submissions must be made via the Secure Web
Incoming Module (SWIM). Due to security reasons, we cannot accept files sent via e-mail or
through our alternate ftp sites.
If you indicated on your “Annual Response Form” that you wished to receive the GUPS
application, you will automatically receive the SWIM URL and a registration token via e-mail.
The e-mail should arrive 5 days after the Annual Response is completed online (or 5 business
days after the Census Bureau receives the paper form).
The registration token allows you to establish a personal SWIM account. If you do not receive a
SWIM token after the amount of time specified, e-mail [email protected] or call
1-800-972-5651.
Once registered, you will no longer need the token to log into the system.
Current SWIM Users
If you are a participant in another Census Bureau partnership program, or participated in a previous
BAS year, and already have a SWIM account, you may use your current account to submit files for the
BAS. You do not need to set up a new account.

For step-by-step instructions to submit files through the SWIM, refer to Table 49. For those
without Internet access, see Section 3.3 below.

USING GUPS (BASICS AND MAP
MANAGEMENT)
After successfully installing GUPS, you are ready to start your BAS updates. There are three
ways to retrieve shapefiles when starting a new project:
•

From the Census Web site (loads directly into GUPS);

•

From DVD (if one was requested); and

•

From My Computer (if you downloaded them to your hardrive).

Table 6 shows the steps to open GUPS and start a new project using the Census Web site.
shows the same steps to open GUPS, but starts a new project using the Census provided DVD
or My Computer (downloaded Census shapefiles saved to your hard drive).

5.1

How to Access BAS Shapefiles

BAS shapefiles from the BAS Web site can be pulled directly into the application when working
in GUPS. Users can load the shapefiles as needed or load multiple county files at once. This is
the preferred method for loading the Census Bureau’s BAS Shapefiles into GUPS as it ensures
that required files are placed in the correct location for the application to access.
Another option for loading files is to download the shapefiles to your hard drive from the BAS
Web site (or from the Census Bureau ftp2 site), then import them into GUPS. BAS shapefiles
are also available for download from the BAS Web site here:
.
Instructions for how to download Census Bureau shapefiles to your hard drive appear in Table 6
and Error! Reference source not found.. Downloading files to your hard drive is not the preferred
method when working in GUPS, and should be used only when necessary (e.g., you need
additional data layers that GUPS does not automatically load and want to pull them in as userprovided data).
If you have requested to receive the shapefiles on DVD, you can also load the files directly into
GUPS from the DVD. Instructions for how to load shapefiles are contained in Table 6: Start a
New Project Using Shapefiles from the BAS Web site.
Whether the files are pulled from the BAS Web site or from the DVD, the GUPS application
unzips them and places them into a pre-established folder created on your computer’s home
directory during the installation process (C:\GUPSGIS\gupsdata\BAS2018\shape). It then
displays them in the application. GUPS then manages the files for you. You do not need to take
any further action.
CAUTION!
Regardless of the source of the shapefiles, it is important that you DO NOT CHANGE any shapefile or
folder name. The files and folders must have the exact names given for the GUPS application to
recognize and load them.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 19

5.2

How to Start a New Project Using GUPS to Import Data from
the Census Bureau’s BAS Website (Recommended Method)

To open the GUPS application and begin your BAS updates, follow the steps in Table 6 below.
Before beginning, note that:
1. If you wish to practice using GUPS without committing the changes you make, simply exit the
system without saving. Before the system closes, it will give you the option to discard the
changes.
2. If you feel comfortable with the system, but you do not want to make all your changes in one
session, simply save your changes, then close the system. When you open GUPS later, it will
allow you to reopen the project and continue working.
Note: In all the Action/Result tables, the action is ususally a command or action you need to perform and
the Result(s) of the action will be shown in italics. For example: if you click the QGIS icon on your
desktop, the software should begin to run automatically.
Table 6: Start a New Project Using Shapefiles from the BAS Web site
Step
Step 1

Action and Result
Double-click the QGIS icon on your desktop.

The QGIS splash screen appears. (Note: QGIS is the open-source platform on which GUPS
is built.)

Step 2

Wait until the application loads (If you have an older computer, this may require a few
minutes). When the GUPS application has loaded, the GUPS main page opens and the
QGIS Tips! box appears.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 20

Step

Action and Result

Note: Since GUPS was built on the QGIS open-source platform, you may see references to
QGIS in several locations within the GUPS application.
Step 3

If you wish to view QGIS system tips, click the Next button to read the first tip. Thereafter use
the Previous and Next buttons to navigate within tips. If you do not wish to see tips again,
click the checkbox in the bottom left-hand corner that reads ‘I’ve had enough tips, don’t show
this on start up any more!’

Step 4

To begin a GUPS project, close the QGIS Tips! box by clicking the OK button. The box
closes and the Map Management dialog box opens, as shown below.

Step 5

In the Map Management dialog box, use the drop-down menu next to the Program field to
select your program, ‘Boundary and Annexation Survey’. ‘Boundary and Annexation’
populates the field.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 21

Step

Step 6

Action and Result

In the Sub Program field, select ‘Boundary and Annexation Survey’.
In the State field, use the drop-down menu to select your state. The scroll bar to the right
allows you to move up and down the list of states.

This example uses Indiana.
Step 7

In the Working County field, use the drop-down menu to select the county for which you
wish to make updates.
This example uses Jefferson County, Indiana.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 22

Step

Action and Result

Independent City Users
Note that the Working County drop-down menu is sorted by FIPS code. Thus you must
search for your city’s code rather than assuming it will appear alphabetically. A portion of the
Working County drop-down list (we used the state State of Virginia for this example)
appears below, showing independent cities near the end of the list because their FIPS codes
are higher.

Step 8

After you select the working county or counties, GUPS asks you to specify the location from
which you want to pull the county’s (or county equivalent’s) shapefile. The Select Data
Folder, Directory or Location box opens.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 23

Step

Action and Result

GUPS will only ask you to specify a location the first time you open a county’s shapefile.
When you come back to work on the same county again, the shapefile will automatically load,
even if you made no changes in your first session.
Step 9

In the Select Data Folder, Directory or Location box drop-down menu, select the location
from which you wish to pull the file. This example assumes the user is pulling the data from
the BAS Web site, so click on ‘Census Web’ in the drop-down menu.

Step 10

Once you click on ‘Census Web’, the shapefile for the county begins to load and progress is
displayed by a blue striped bar (color may vary), with the percentage of the upload completed
displayed to the right.

Step 11

Step 12

Once finished loading, the Map Management screen allows you to now enter the the entity
type.
In the Entity Type field drop-down menu, select the entity type you represent. The options
are ‘Consolidated City’, County’, ‘Minor Civil Division (MCD)’, ‘Place’, and ‘State’.
Note: The options you see may vary, depending on the entity types your state contains.
Independent city users should select ‘Place’.
This example assumes a ‘County’ user.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 24

Step

Step 13

Action and Result

After the entity type is selected, an Entity Name field appears. Since you selected the entity
type ‘County’, and you already named Jefferson County as your working county, GUPS
automatically fills the Entity Name field with ‘Jefferson County.’

If you select ‘Consolidated City’ as your Entity Type, the name of the consolidated citycounty government automatically fills the Entity Name field.
If you select ‘Place’ as your Entity Type, the Entity Name field is blank. A drop-down menu,
which lists all incorporated places within the working county, allows you to select your entity.
If you select ‘State’ as your entity type, the state you selected in the State field automatically
fills the Entity Name field.
Step 14

In all cases, a list of the counties in the state appears at the bottom of the Map Management
dialog box.
Adjacent counties (counties whose borders touch the working county) are highlighted in
yellow and checked.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 25

Step 15

Action and Result

All checked counties will display in the Map View. Uncheck the box for any county you do not
wish to see.
To select additional counties to display (you may choose up to a total of 10 at once), check
the checkboxes next to them. Scroll down using the scroll bar to the right to see the full list of
counties.

Step 16

For this example, we select neighboring Clark and Jennings Counties. Check the checkboxes
next to these counties, then click the Open
Management dialog box.

Step 18

button at the bottom of the Map

As GUPS loads the data, it unzips and copies the files to a folder that was created on your
computer’s home directory during the installation process. It then pulls the file into the GUPS
application.
The data layers for Jefferson County appear in the Table of Contents and the maps for the
selected adjacent (or other selected counties) appear next to that for the working county in
Map View. In our example, as shown below, Map View displays the maps for Jennings and
Clark Counties next to that for Jefferson County.

Action and Result

Step 20

If for any reason shapefiles are missing from the location you chose in the Select Data
Folder, Directory or Location drop-down menu, or the files are corrupted and cannot be
loaded, you will receive an error message such as the one shown below.

Step 21

Click OK to return to the Map Management dialog box.

Step 22

You may try loading the file(s) from another location. Simply click the Open button at the
bottom of the Map Management box.
The Select Data Folder, Directory or Location dialog box reopens, allowing you to select
another option for securing the files.

If you have trouble loading shapefiles using the ‘Census Web’ and ‘CD/DVD’ options, follow
the instructions in Error! Reference source not found. or Table 8 to download the files to
your computer from the BAS Web site or Census Bureau’s ftp2 site. Then pull them into
GUPS using the ‘My Computer’ option in the Select Data Folder, Directory or Location
drop-down menu. When you select ‘My Computer’ the Select directory screen opens.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 27

Step

Action and Result

On this screen, click on the My Computer icon in the left-hand corner.
Navigate to the location of the files you want to load, then select the files and click on the
Select button at the bottom of the Select directory screen. GUPS unzips and loads the files,
then moves them to the pre-established folder on your home directory.
Step 23

After working on a project, be sure to save before exiting. Otherwise your edits will be lost. To
save, click the Save icon on the Standard toolbar.

The Current edits pop-up box asks if you want to save the changes for all layers.

Click OK. The changes are saved.
Step 24

If you do not wish to save your changes, simply close the application (click the red X in the
upper right-hand corner of the main GUPS page). A Save? pop-up warning asks if you want
to save the project.

Click Discard not to save your project.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 28

Step
Step 25

Action and Result
To reopen a saved project, in the Map Management dialog box, click the down arrow next to
the Open Recent button. The drop-down menu opens with your project listed.

If you share a computer with other GUPS users, multiple project files may appear in the dropdown menu, as shown below. Here three separate users in Mississippi have created projects
on the same computer.

To identify which of the entries in the list represents your project, look at its number string.
This string comprises your BAS ID. Each BAS ID is 11 digits. The first digit indicates the
Entity Type (i.e., the user type) (0 = consolidated city; 1 = incorporated place; 2 = county; 3 =
MCD; and 7 = state). The next two digits are the state FIPS code. The following three digits
are the FIPS code for the working county (these digits are ‘000’ for incorporated places). The
final five digits are the FIPS code for the specific incorporated place, consolidated city, or
MCD that created the project (for counties, these digits are ‘00000’ since the county is
already identified in the string).
The number string,
reflects a project created by a Place user (for the
City of Lena) in Mississippi, where 1 = incorporated place; 28 = Mississippi FIPS code; 000 =
placeholder number for non-county entities (if the user were a county user this number would
be the FIPS code for Chickasaw County, or 155); and 40360 = the place FIPS code for Lena.
If you do not know the BAS ID information for your particular geography, it is available within
the Map Management dialog box. Below is an example for Hanover Township, an MCD in
Jefferson County, Indiana.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 29

Step

Step 26

Action and Result

Once you have identified the correct file to reopen, select it from the list. The map for the
project automatically loads and the layers show in the Table of Contents.
Census Bureau-defined default layers and view settings are loaded each time you start a
new project in GUPS.
If you change these settings for a project, when you save the project your new settings are
also saved. Thus, when you reopen the project, the Table of Contents and Map View
display the layers and the map according to the settings you were last using rather than
returning to the Census Bureau default settings.
To restore the default settings for a layer:
•

Click on the layer in the Table of Contents. A drop-down menu opens.

•

In the drop-down menu, select ‘GUPS Layer’. A submenu opens.

•

In the submenu, select ‘Load default style’ (see illustration below).

To reset the default settings for all layers, select ‘Load all default style.’

Boundary and Annexation Survey Respondent Guide: GUPS

Step 27

Action and Result

When you reopen a project, also note that any previously selected adjacent (or other
selected) counties appear in cyan blue and remain checked. Other adjacent counties that
have not previously been selected appear in yellow and are also checked, as shown below.

You may load files for additional counties at this point if you wish.
Loading Multiple Files at Once
The limit to how many county datasets can be loaded at once is 11 (the working county plus
10 other counties). To load shapefiles for additional counties, after the first 10 are loaded:
•

Leave the same working county selected in the Working County field.

•

Uncheck the already loaded counties in the Map Management dialog box list.

•

Check the checkboxes for the additional counties (up to 10) that you wish to add.
Click the Open button and after the Select Data Folder, Directory or Location box
opens, use the drop-down menu to select the source of the files. Repeat this process
as many times as needed.

The state folders are represented using two-digital state FIPS codes.

Step 6

There are several sets of shapefiles within each state directory. You will want to download
the most recent partnership shapefiles. These shapefiles are contained within a zip file
with the prefix partnership_shapefiles_18v2. Each zip file ends with a five-digit statecounty FIPS code (e.g., 08051) which represents the county for which you are
downloading data. Make sure to choose the filename with “18v2”, because the “18v1”
files are sometimes also available in the folders.

Step 7

Select the county or counties that you intend to download and copy to your local or
network drive. You may copy the files to any location you wish. When you select your
geography in GUPS, the application asks you to specify the location (‘CD/DVD’, ‘My
Computer’, or ‘Census Web’) of your files. When you select ‘My Computer’, GUPS asks
you to select a directory. Navigate to the location where you saved the files and select
those you wish to upload. GUPS unzips and loads the files, then moves them to the preestablished folder on your home directory.

Select/Deselect Features Using the Select Features and Deselect
Features Buttons

The Select Features button gives you several ways to select features on the map. The
Deselect Features from All Layers button allows you to deselect features you previously
selected. Table 14 describes each of the feature selection methods, discusses when one might
be preferable over another, and explains how to deselect features.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 51

Table 14: Select / Deselect Features on the Map
Step

Action and Result

Step 1

To begin, click on the layer name in the Table of Contents for the layer in which you want to
select a feature. For example, if you want to select linear features, click on the ‘edges’ layer;
if you want to select faces, click on the ‘faces’ layer.

Step 2

Click once on the Select Features button on the Standard Toolbar.

Step 3

To select an edge or face on the map, click on it. In this example, we have selected ‘faces’ in
the Table of Contents and clicked on a face. The face selected turns cyan blue (color may
vary).

Step 4

To select more than one face, hold down the CTRL key while clicking on the additional faces
you wish to select. This method is suited to instances where you want to select faces that are
not contiguous, as shown below.

You can also select multiple features by simply clicking the Select Feature button, then
dragging your cursor over the features. This method is convenient when you want to select a
large number of contiguous faces or a large number of nearby linear features without having
to click each, one by one.
A Note on GUPS Tools
GUPS tools remain active until a different tool is selected. For example, if you use the Select
Features tool to choose faces for a new area landmark, then decide you would rather add a
new linear feature instead, you must click the Add Linear Feature tool before you click on
the map again. If you do not, the Select Features tool, still active, selects a face.

Boundary and Annexation Survey Respondent Guide: GUPS

Action and Result

Step 5

To open other Select Features options, click on the down arrow to the right of the Select
Features button. The Select Features drop-down menu opens.

Step 6

The first option in the menu, ‘Select Feature(s)’, duplicates the functions available when you
click on the main button on the toolbar.

Step 7

The second option, ‘Select Features by Polygon’, allows you to draw a polygon on the map
to select features. To use this feature select it in the drop-down menu, then follow the steps
below.

Step 8

Left-click on the map where you want to begin the polygon. Drag your cursor to extend the
line to the point you want, left-click, then extend the line in a new direction. Continue until you
have a closed polygon, as shown below.

Step 9

When you are done, right-click. (This tells the system you have finished drawing). All faces
with an edge appearing within the polygon are highlighted in cyan blue.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 53

Step

Step 10

Action and Result

The third option, ‘Select Features by Freehand’, allows you to use your cursor to draw a
variety of shapes to select a face or faces.

To use this option, click on the map and use your cursor to draw any shape (polygon,
triangle, circle, etc.). If the shape does not cross any edges, the single face in which the
shape is drawn is selected and turns cyan blue. If the shape crosses several faces, all faces
whose edges are crossed are selected and turn cyan blue.
Note: This method is particularly useful when attempting to select a very small face. You
may draw a tiny triangle, for example, within a face to select it.
Step 11

The final option, ‘Select Features by Radius’, allows you to use your cursor to draw a circle
to define the features you want to select.

To use this tool, left-click on the map where you want to begin, then hold down the mouse
and drag the cursor outward to expand the circle. Release the mouse when you are done.
The feature(s) selected is(are) highlighted in cyan blue.
Step 12

You can either deselect polygons selected by holding and using the same selection option to
deselect by holding CTRL and retracing over the polygons, or deselect a feature or features
automatically by clicking the Deselect Features from All Layers button (next to the Select
Features button) once.

The selected features in all layers are deselected.

Select an operator from a full list by clicking the ‘+’ sign next to “Operators’ in the Functions
pane. OR If you need a commonly used operator such as equals, plus, or minus, click its
corresponding button in the row of buttons at the top of the Expression pane.

Step 5

In this example, we need the operator for equals. Double-click the ‘=‘ operator button. The
expression in the Expression pane now reads “BBSP Flag” =.

Step 6

To select a specific value for the field “BBSP Flag”, click either the all unique or 10 samples
button in the Load values field. The Values field above the buttons populates with all allowed
values.

Step 7

Select a value. We will select ‘4’ by double-clicking on it in the Values field list. The
expression changes to “BBSP Flag” = ‘4’.

library data provider plugin, such as ESRI shapefiles, MapInfo MIF (interchange format), and
MapInfo TAB (native format). It also supports PostGIS layers in a PostgreSQL database and
SpatiaLite layers. Support for additional data types (e.g., delimited text) is provided by additional
data provider plugins.
Below are the steps to import the most commonly used data formats. To upload shapefile or
geodatabase data layers, follow the steps in the table below.
Note: You May Only Upload One User-Provided Data Layer at a Time. If you have multiple data

MAKING BAS UPDATES IN GUPS
The tables in this section provide step-by-step instructions for making BAS updates. The
examples assume you have read and understood the directions for opening GUPS and using
Map Management. If you do not yet feel comfortable with Map Management, please review the
contents of Section 5: Using GUPS (Basics and Map Management) before you begin making
updates. It is highly recommended to use a souce of imagery data when making any BAS
updates.
All examples shown here, although using real data, are purely fictitious. They are employed for
purposes of illustration only and do not indicate any actual geographic changes.

How to Update Legal Boundaries

6.1.1

Recording an Annexation

Follow the steps in Table 26 to record an annexation. The fictitious example in this table looks
at an incorporated place named Kissimmee, Florida. Kissimmee has annexed several parcels
previously outside its city limits.
Table 26: Record an Annexation
Step

Action and Result

Step 1

Open in Map View the county that contains the place (or other legal entity) that is annexing
area. Be sure that you have all layers you wish to see on the map checked in the Table of
Contents.

Step 2

Click the Modify Area Feature button on the BAS toolbar.

The Modify Area Feature dialog box opens.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 68

Step

Action and Result

Step 3

Click the drop-down area next to the Geography field, and select the entity type (here
‘Place’), from the drop-down menu. A list of all incorporated places in the county appears in
the Info list in the bottom portion of the dialog box.

Step 4

Double-click on the row in the list for the place that is making the annexation (here
‘Kissimmee city’). (Note: The list of places is short, but in some cases it can be long. Use the
scroll bar to the right of the list to move up and down the list, if needed.) Once you doubleclick on the row, the map zooms to the place selected.

Step 5

If the map does not zoom to a scale sufficient to make your changes, click on the Zoom in
button on the Standard toolbar.

Step 6

To select the faces you want to add to the place, click on the small down arrow next to the
Select Features button on the dialog box toolbar. The Select Features button drop-down
menu opens. In this example we will use the “radius” method to select the faces we want to
add to Kissimmee. Click on ‘Select Features by Radius’ in the menu.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 69

Step

Step 7

Action and Result

Next, go to the map and place your cursor where you want to add the faces.
To select a single face, simply drag the cursor outward in the center of the face. To select
multiple faces, drag the cursor across the edges that separate the faces. In this example, we
select seven faces. The faces selected turn cyan blue (color may vary).

Because all geographic areas consist of faces, you may need to “split” a face to accurately
reflect an entity’s boundary. To split a face, digitize a new line that represents the boundary’s
location (click on Table 33 for instructions to add a linear feature) and assign it the
appropriate MTFCC. This splits the original face into two faces. You can now select the face
you need to add to the new entity.
If you accidentally select a face you do not wish to include, you can use the Deselect
Features from All Layers option in the Select Feature(s) drop-down menu to clear the
selected faces from your screen and start over.

Step 5

Then click on the map to select the face or faces.
If the entity includes only a single face, you may simply click once on the face to select it. If
the entity includes several contiguous faces, after clicking on the first face, depress the
CTRL key and while holding it down, left-click on each additional face to be added. The
selected faces turn cyan blue (colors may vary).

Note: You may also select faces (after clicking the Select Features button) by simply
dragging your cursor over the edges that mark their boundaries. Additional means of
selecting faces (by polygon, by freehand, and by radius) are discussed Table 14:

assigned.
Step 15

To make additional changes to the map, simply make a new selection in the Modify Area
Feature dialog box Geography field and continue work. You may save your changes as
you go or wait until you have finished all work on the map. Saving as changes are
completed, however, is recommended to avoid losing work in the event of a power outage or
system interruption.
New Entity that Crosses a County Boundary
If the new entity crosses a county boundary, you must add the new entity in both counties
separately. After making the change in your working county, return to Map Management,
select the other county as the working county, and proceed to add the new entity in this
county as well. If the added entity crosses more than one county boundary, complete the
addition in each county affected.

Making a Boundary Update on a County Line

Users reporting on behalf of an incorporated place may make changes across county
boundaries for their place. The steps in Table 30 below provide an example for an annexation
by a place across a county boundary. The fictitious example uses Brooklyn Village, in Dane
County, Wisconsin. It has annexed land in adjacent Rock County.
Table 30: Record an Annexation in an Adjacent County
Step

Action and Result
Independent City Users: Users reporting for independent cities (cities independent of any
county and treated by the Census Bureau as county equivalents) should follow the steps
described below to show annexations / deannexations between the city and surrounding
counties. County Users: When updating a county boundary, you must switch the working
county to add / remove area located in the other county. To update a boundary, use the
instructions below, but in Step 6, select County instead of Place in the Geography drop-down
menu, and in Step 7, click in the Info list on the name of the county to which you want add or
remove the area.

Making a Legal Boundary Change for a Consolidated City

Users who represent consolidated cities (i.e., cities that share a consolidated government with a
county or minor civil division) should follow the steps described in Table 30 in Section 6.1.5:
Making a Boundary Update on a County Line to show boundary changes between the city
and any county adjacent to it. To show boundary changes between the consolidated city itself
and the entity or entities with which it shares a government, proceed as any incorporated place
user would. That is, if you wish to annex land from another entity within the consolidated
government area, treat it as you would any annexation within a county.

6.1.7

Making a Boundary Correction (Add Area/Remove Area)

To make a boundary correction that adds or removes area from an entity, follow the steps in

Boundary and Annexation Survey Respondent Guide: GUPS

Page 96

Table 31. In this fictitious example, a boundary correction is made to the city limits of Linwood,
Kansas.

Action and Result

Click the down arrow next to the Select Features button to select the face(s) to add or
remove for the boundary correction. The Select Features drop-down menu opens.

In this example, we are adding three small faces that are difficult to select, so we opt for
‘Select Features by Freehand’. This method allows us to place our cursor inside the first
face and draw a tiny line. The selected face turns cyan blue (colors may vary).

To select the other faces, press the CTRL key, and while holding it down, repeat the action
for the two remaining faces. All three faces turn color.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 99

added linear feature and the name you assigned appear on the map.

Adding a linear feature coincident with a boundary – The GUPS will not allow one linear
feature to be placed over another. For example, if you attempt to add a road overlaying a
legal boundary line, a pop-up box will warn you ‘Added Line Overlays an Existing line’. If you
are adding a linear feature coincident with a boundary, follow the instructions for updating
linear feature attributes instead (for instructions click on Table 36). Once you select the
boundary edge that you want to add a street on top of, update the MTFCC in the Update
Attributes pop-up to one of the "S" class feature codes (e.g., S1400) and add a name in the
FULLNAME field.

6.2.2

Deleting a Linear Feature

To delete a linear feature, follow the steps in Table 34.
Table 34: Deleting a Linear Feature
Step

Action and Result

Step 1

processed for deletion when the Census Bureau receives the BAS file.
Note: If you have multiple linear features to delete, you may click the Delete Linear
Feature button on the toolbar once, then press CTRL and click each of the features you
want to delete. GUPS will delete all of the linear features selected. You may also drag your
cursor over multiple linear features to select them.

You may also backspace over the name to clear the field. Then type in the new name.

Step 6

If you need to correct the MTFCC code, click on the down arrow to the right of the field to
open the drop-down menu and select the correct MTFCC from the menu.

Step 7

Change the address range for the linear feature, if necessary. Type in potential address
ranges in the LTOADD (left to address); RTOADD (right to address); LFROMADD (left from
address); RFROMADD (right from address) fields based on the directional arrows. The
directional arrows show the origin node (FROM) and the end node (TO).

Step 8

Click Save button at the bottom of the Modify Linear Feature Attributes dialog box.
The address ranges for all features are blank in the geographic partnership shapefiles
because the ranges are stored in tables separate from the shapefiles. You can provide
address ranges in these fields, but be aware that we may already have address ranges.
It is important to note which node is the FROM node and which is the TO node (based on
the red directional arrows) so that the address ranges are associated with the correct side
of the street and the correct census block.
Note: Provide potential address ranges for blocksides, such as 0-98, 100-198, etc., for
even parity and 1-99, 101-199, etc., for odd parity address ranges. Do not provide actual
address ranges.

How to Use GUPS Review and Validation Tools

GUPS provides two tools—the Geography Review tool and the Review Change Polygons
tool to help you review and validate the updates you have made in the system.

6.5.1

Geography Review Tool

The Geography Review tool filters the map layers based on various fields in the attribute table.
You can use this tool to check the changes you made to linear features, area landmarks, point
landmarks, and legal boundaries anywhere within a county (you may also view the attributes of

Step
Step 2

Action and Result
In the Layer Name: field drop-down menu, select the data layer you want to view:

In this example, we selected the file “bas18_25510500000_55105_changes_alndk.” This
is the transaction data output file for the area landmark layer (note the word “changes” in
the file name to indicate the layer has been updated).
Step 3

Once you make your selection, the attribute table for the layer opens, with the attributes
for each area landmark you changed displayed in a separate row.

To see an area landmark on the map, click its row in the attribute table, then click the
Zoom button (the row is highlighted and the map automatically zooms to the landmark
selected, which is highlighted and shows changes made in cyan blue – colors may vary).

Action and Result

Step 5

To view other area landmarks listed in the table rows, use the Previous Zoom and Next
Zoom buttons. The previous or next row highlights and the system zooms to the map for
that row.

Step 6

You may use the Search feature at the bottom of the dialog box to filter the table layers by
specific attributes (e.g., full name, MTFCC, change type, etc.).

Step 7

First, select the layer you want to view (in this example, we will select the county
subdivision layer).

For each feature changed for a county subdivision, the attributes of the changed feature
display in the table rows. Each column gives the name of the attribute.

Step 8

Action and Result

In the Column Name drop-down menu, select the attribute by which you want to filter.

In this example, we will select change type (CHNG_TYPE).
Step 9

Finally, in the Select drop-down, select the attribute value by which you want to filter, then
click the Search button. In this example, we will select ‘Boundary Correction’.

After you click Search, the attribute table is filtered to show the rows for all boundary
corrections made in the county subdivision layer.

Boundary and Annexation Survey Respondent Guide: GUPS

Step 10

To view an individual boundary correction, click on its row and click the Zoom button.

Step 11

To return to the attribute table to see the full (unfiltered) county subdivision layer, click the
Refresh

button in the upper right-hand corner of the dialog box.

Note that when filtering the table by some attributes (e.g., state and county FIPS code or
MTFCC), no drop-down list appears from which to make a selection. This is because
some attribute codes are too numerous to make scrolling through a list practicable.
Instead you will receive a blank box in which you may type the search value. For example,
if you are filtering the area landmarks layer by MTFCC and want to see hospitals in the
layer, type in the MTFCC for hospitals (K1231), as shown below, then click Search.

6.5.2

Reviewing Change Polygons Tool

Boundary and Annexation Survey Respondent Guide: GUPS

Page 134

Notes on Reviewing Change Polygons
You must run the Review Change Polygons tool before GUPS will export a file.
You must run the Review Change Polygons tool for each county in which you worked. For example,
if you made changes to your working county, but also made changes to an adjacent county when
annexing land for your county, you must run the change polygon check on both counties.

To use the Review Change Polygons tool, follow the steps in Table 45.
Table 45: Reviewing Change Polygons
Step
Step 1

Action and Result
In the Map Management dialog box, make sure the county for which you want to run the
check appears in the Working County field.

Once you click the Open button at the bottom of the dialog box and the map opens in Map
View, you are ready to run the Review Change Polygons check.
If you made changes in more than one county, you must run the check for each county in
which you worked. This means that after completing the check for one county you must
return to Map Management and select the additional county in which you worked as the
working county. Then run the check on it. Repeat this process until you have run the check
for all counties in which you made changes.
If you did not make any changes in another county, you need only run the check for your
county.
Step 2

Once you have loaded the working county, you are ready to begin the change polygons
review.
Click on the Review Change Polygons button on the BAS toolbar.

The Review Change Polygons dialog box opens just below the Table of Contents.

Boundary and Annexation Survey Respondent Guide: GUPS

Step

Action and Result

Note: This box can be dragged anywhere on your screen and docked.
Step 3

Use the Geography drop-down menu shown below to select the geography you want to
review. In this example, we have selected ‘MCD’.

Step 4

After you select an entity type, the Small Area Check and Find Holes buttons become
active and all change polygons for the entity type you selected appear in the Info list at the
bottom of the box.

Step 5

To check for small area change polygons, click the Small Area Check button. If all your
change polygons are of sufficient size, a pop-up box informs you of this.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 136

Step

Action and Result

Step 6

If you have small area polygons within an MCD in the working county, they appear in the Info
list with their acreage noted in the Area in Acres column. The Display All Changes button
also becomes active (this button allows you to toggle back to see all change polygons in the
list).

Step 7

To view a polygon on the map, click the row for the polygon in the Info list. The polygon is
highlighted and the map zooms to the location of the polygon.

Note in the illustration above, we moved the Review Change Polygons box to sit over the
map. As stated earlier, you may move the box anywhere on the page and dock it.
Step 8

To delete polygons that are too small (less than 500 square feet), click on the row for the
change polygon in the Info list. The Delete Change Polygon button appears.

Step 9

To delete the polygon, click the Delete Change Polygon button. A pop-up box asks if you
are sure you want to delete.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 137

Step

Action and Result

Step 10

Click the Yes button. The polygon is removed from the list, from the map, and from the
attribute table.

Step 11

Before the Small Area check is complete, you must repeat the steps above for each
geography type for which you created change polygons.

Step 12

Next, review your polygons for holes (that is, two or fewer small faces missed when creating
a change polygon). While still in the Review Change Polygons dialog box, select a
geography type from the Geography drop-down menu. For this example, we again selected
‘MCD’. A list of change polygons for MCDs in the county populates the Info list and the
Display All Changes button replaces the Small Area button (since you’ve already run this
check). The Find Holes buttons remains in its original location.

Step 13

Click on the row for the polygon in the Info list to see it on the map, then click the Find Holes
button. If no holes are present, a pop-up box informs you of this.

Step 14

If holes are found, a list of polygons with holes appears in the Holes Review box and the Fix
button activates at the bottom of the box.

Step

Action and Result

Step 15

To correct a change polygon, click on its row to highlight it. The map zooms to its location
and displays all holes in cyan blue (color may vary).

Step 16

Click the Fix button to repair the hole. The change polygon is corrected and the correction
displays on the map (i.e., the hole is changed to the same color as the remainder of the
polygon).

Step 17

Before the Find Holes check is complete, you must repeat the steps above for each
geography type for which you created change polygons.

Boundary and Annexation Survey Respondent Guide: GUPS

Page 139

Step

Action and Result

Step 18

After you review for small areas and holes, you may also use the Review Change Polygons
tool to check the general accuracy of your change polygons. To do so, select your entity type
in the Geography drop-down menu. A full list of change polygons for the geography type
selected displays in the Info list.

Step 19

Click on the row for each polygon to see it on the map and review your changes.
If you notice a mistake on the map (e.g., you created a new incorporated place that was
supposed to have six faces, but you selected only five), click on the Modify Area Feature
button on the BAS toolbar and make the correction.

Step 20

To review boundary changes, select the entity type you want to review in the Geography
drop-down menu at the top of the Review Change Polygons dialog box. In this example, we
select ‘Place’. All boundary change polygons for the entity type selected populate the Info
list.
To review a boundary change, click on the change polygon in the list, then click the Legal
Entity Change button at the bottom of the Review Change Polygons dialog box, shown
below.

The map zooms to where the change was made and a box opens displaying the information
that you entered when you coded the change. Here, because the change was a boundary
correction, the effective date, authority type, and documentation fields are not filled.

If this change was mistakenly coded as a boundary correction, and should have been a legal
change instead, you may correct the error here. In this example we correct a change polygon
mistakenly coded as a boundary correction rather than an annexation.

Step

Action and Result

Step 21

Click the calendar icon next to the EFF_DATE field to select an effective date for the
annexation.

Step 22

Step 23

In the DOCU field, type in the ordinance or other legal documentation number authorizing the
annexation, or upload legal documentation for the change. To upload documentation, click
the folder icon next to the DOCU field.

When the DOCU window opens, click on the icon for ‘My Computer’ (or simply ‘Computer’ in
some Windows versions) to open the directory where you have saved your documentation.

Your directories display, as shown below.

Step 24

Step 25
Step 26

Finally, in the CHNG_TYPE field drop-down menu, change ‘Boundary Correction’ to the
correct change type (‘Annexation’, ‘Corridor’, or ‘Offset’). Here we select ‘Annexation’.

Click the OK

button. The correction is made.

When you have completed all your reviews (for small areas, holes, and boundary changes)
for all entity types, and have made any corrections needed, click the Save
button on the
BAS toolbar. All corrections are saved. Your Review Change Polygons check is complete.

Step 27

If you made changes in more than one working county, return to Map Management, select
the additional county as your working county, and repeat the steps above. Repeat this
process as many times as needed until you have run the Review Change Polygons check
on all the counties in which you made changes.

How to Export ZIP Files to Share/Submit

When creating ZIP files to export, you have two options—you may export the file to share with
another user or you may export the file for submission to the Census Bureau. In either case,
GUPS automatically names the output ZIP file for you. It packages all the files required by the
Census Bureau (including any documentation you uploaded) into the ZIP file and saves it in a
preset location created on your computer by during the installation process.
Important Note
If you make changes to more than one working county, you must export a separate ZIP file for each.

TERMS
Areal Feature - is a prominent and identifying feature of a landscape significant enough to
warrant name recognition, such as a lake, park, school, military base, or cemetery, etc. This
type of feature class is only assigned to a face geometry. Any face can be assigned to multiple
features. For example, a water body can also be part of a park.
Edge - is a one-dimensional object (legacy 1-cell), bounded by two nodes: a start node and an
end node. Its geometry is distinguished by the coordinates of the start and end nodes, and
additional coordinates that are ordered and serve as vertices (or shape points) between the two
nodes. An edge is a primitive feature in the Oracle database.
Effects of having Edge features in the MAF/TIGER Database(MTDB):
•

Represents an invisible boundary line for various geometry, geographic and statistical data. and
can stand alone.

•

A linear feature always occupies the same space as an edge and there are attributes on an edge
that are only relevant when a linear feature exists.

Face - is a two-dimensional object (legacy 2-cell) bounded by two or more edges. Its boundary
includes not only the edges that separate it from other faces, but also any interior edges (twodimensional topological primitives) contained within the area of the face.
Geographic Area - is a demarcated area used for the collection and/or tabulation of Census
Bureau data.
Geographic Corridors - is an area that includes only a road (or other feature’s) right-of-way
and does not contain any structures. Figure 13. Annexed Area Corridor and Unincorporated
shows a corridor that has been created where an incorporated place annexed the road right-ofway, but not the housing units assigned to either side of the road (these belong instead to an
unincorporated area). If it is important to the incorporated place that its ownership and/or
maintenance of the road and/or its right-of-way be displayed on Census Bureau’s maps, a
geographic corridor should be created. However, the Census Bureau does not require places to
report rights-of-way: maintaining geographic corridors in a nationwide database is difficult and
impractical, and the right-of-way should only be included if it is crucial to the place, or if state or
local laws require it. The Census Bureau would actually prefer that the area simply not be
assigned to the place at all.
Figure 14. shows an example where the right-of-way belongs in an unincorporated area, while
the housing units along it are included in an incorporated place (shown in color). While depicting
this corridor may be important for local purposes, it is not relevant for Census Bureau
tabulations and is not easy to depict in the Census nationwide database. This type of corridor
should not be included in a BAS response.
Please note that the Census Bureau does not require places to display rights-of-way or road
maintenance corridors that do not contain or potentially contain housing or population. If local or
state law does not require depiction of these geographic features, the Census Bureau prefers
that they be left off BAS submissions. However, if it is necessary for the place to depict them,
then they must be submitted as a geographic corridor.

Figure 13. Annexed Area Corridor and Unincorporated Area

Figure 13 - A corridor that has been created where an incorporated place annexed the road
right-of-way, but not the housing units assigned to either side of the road.

Figure 14. Incorporated Area and Unincorporated Area

Figure 14 - The right-of-way belongs in an unincorporated area, while the housing units along it
are included in an incorporated place.
To recap, when a participant has a case where a road right-of-way is legally included in the
boundary, but the adjacent parcels/houses are not, there are two options. You should either not
include the area in the place at all (Scenario A in Figure 15. Participant Responses), or
include it in the place and flag it as a corridor (Scenario C in Figure 15. Participant
Responses). What you should never do is include such areas within the place boundary without
flagging them as corridors (Scenario B in Figure 15. Participant Responses).

Figure 15. Participant Responses

Figure 15 – (A): The respondent did not include place ownership of the road or the right-of-way,
allowing houses along the road to be geocoded correctly. (B): The respondent chose to show
Boundary and Annexation Survey Digital Respondent Guide: GUPS

Page B-2

place ownership of the road, but did not flag it as a corridor, causing houses along the road to
be incorrectly geocoded.(C): The respondent chose to show place ownership of the road, and
flagged that ownership as a corridor, allowing the houses to be geocoded correctly. Both A and
C are acceptable.

Geographic Offsets
A geographic offset is an area (either within or outside of a geographic entity) that is only on one
side of a road (unlike corridors, which involve both sides of the road) and does not include
structures addressed to that side of the road. Much of the same guidelines regarding corridors
also holds true for offsets.
The Census Bureau is aware that many governments base their legal boundaries on cadastral
(parcel-based) right-of-way mapping. Census Bureau maps are based on spatial data that is
topologically integrated which makes maintenance of geographic offsets inefficient. Using the
road centerline wherever possible will help to establish more accurate population counts. If a
boundary follows a front lot line, the Census Bureau strongly prefers that the road centerline be
used as the boundary. If a boundary is at the rear of a lot, then it should be depicted as such. If
it is unclear whether a particular line is a front lot line or something else, please contact the BAS
team for assistance. As a rule, if a house or building could not conceivably be built in the area
between the potential line and the centerline of the road, then the line can be considered a front
lot line. Figure 16. A Cadastral (Parcel-Based) Boundary Map depicts a cadastral (parcelbased) boundary map and Figure 17. How a Boundary Should be Represented When Sent
to the Census Bureau shows how the boundary should be represented when it is sent to the
Census Bureau.

Figure 18. Place Boundary – Front Lot Line
Figure 18 - Shows a situation in which the place boundary is along the front lot line. In this example, the
respondent must either use the road centerline as the boundary (preferred), or create an offset.

Figure 19. Place Boundary – Rear Lot Line
Figure 19 - The place boundary is on the rear lot line, so the respondent should of course not use the road
centerline or create an offset, but should rather digitize in a new boundary following the rear lot line.

The Census Bureau has included an “offset” shapefile in the BAS materials
(bas_2018_offset_.shp), so that your jurisdiction can be checked for any existing
corridors or offsets. While the Census Bureau prefers that new offsets are not created (see
above), this information can be helpful in determining if current boundaries are correct.
Linear Feature - is a single dimension feature (Road/Path, Hydro, Rail, or Miscellaneous) along
one or more edges.
Point Feature - is an isolated node not connected to an edge. The XY coordinate point is where
a structure resides. Point Feature structures include housing units and legacy point landmark of
public facilities such as libraries, police stations, schools, churches, malls, and some
monuments.

Boundary Review – Quality Control

1) Verify that all mandatory fields are populated.
2) Verify that all legal changes (annexations, deannexations, new incorporations, and disincorporations) have appropriate legal
documentation, authorization types, and effective dates.
3) Verify that all boundary corrections less than thirty feet are not dissolving boundary to feature relationships (with roads,
railroads, hydrography, etc.)
4) Verify that all boundary changes are greater than thirty feet, unless they include housing units.

File Naming Conventions and Submission Prep

1) Name all return files (change polygons, linear feature updates, whole entity files, etc.) using the file naming conventions
outlined in the Digital BAS Respondent Guide. The table below contains examples of the file naming conventions.
2) Include important metadata information. It is critical that all return files have *.prj files
3) Include a text file with the BAS and HEO contact information, or update the contact information using the online Annual
Response Form.
4) Zip all return files together and name the file bas18__return.zip. should be replaced with your eleven digit
BAS ID code (e.g. bas18_20100100000_return.zip)

INTRODUCTION

The Boundary and Annexation Survey

The U.S. Census Bureau (Census Bureau) conducts an annual survey called the Boundary and
Annexation Survey (BAS) to collect information about selected legally defined geographic areas,
such as counties (and equivalent areas), incorporated places, minor civil divisions (MCDs),
federally recognized American Indian Areas (AIAs) — including reservations, off-reservation
trust lands and tribal subdivisions, Hawaiian Homelands, and Alaska Native Regional
Corporations (ANRC). BAS also provides an opportunity for participants to review the names
and geographic relationships for these areas. Title 13, U.S.C., Section 6, authorizes this survey.
The Census Bureau uses the boundary information collected during the BAS to tabulate data for
the decennial and economic censuses, and to support the Population Estimates Program (PEP)
and the American Community Survey (ACS). Maintaining correct boundaries and boundary-tofeature relationships through the BAS helps ensure that the Census Bureau assigns the
appropriate population to each governmental unit (GU).
In compliance with the Office of Management and Budget Circular A-16, the BAS supports the
Census Bureau’s spatial data steward responsibilities for the Federal Geographic Data
Committee (FGDC) and the Geospatial One-Stop by updating the inventory and boundaries of
GUs.
In addition, the BAS is the source of up-to-date information on changes to the boundaries,
codes and names of incorporated places, MCDs, counties (and equivalent areas), Hawaiian
Homelands, ANRC, and federally recognized AIAs, which include reservations and offreservation trust lands used by the U.S. Geological Survey’s (USGS), the National Map, and the
Geographic Names Information System (GNIS).
Please visit the BAS program Web site at .
For more information on the BAS, please view the “Introduction to BAS” video series on the
Census Bureau’s BAS Web site at

What’s New for the 2018 BAS?
1. The Geographic Partnership Support Desk (GPSD) is now fully functional and available
to assist with any questions respondents may have regarding BAS.
2. Redistricting data contacts participating in the Voting District Project (VTD) may submit
boundary updates for reconciliation with BAS contacts.

Key Dates for BAS Respondents

January 1, 2018 — All boundary changes must be legally in effect on or before this date to be
reported in the 2018 BAS.
March 1, 2018 — BAS submission date deadline for boundary updates to be reflected in the
ACS and PEP published data. Boundary submissions received by this date are also reflected in
next year’s BAS materials.
Boundary and Annexation Survey Respondent Guide: Paper

Page vi

May 31, 2018 — BAS boundary updates submitted by this date will be reflected in next year’s
BAS materials.

BAS State Agreements

The Census Bureau has established a number of agreements with states for reporting boundary
changes. Please visit the BAS State Agreements webpage within the BAS program Web site at
or call
(800) 972-5651 for information regarding state agreements.
Note: The Census Bureau can only establish BAS state agreements for states that require local
governments to report boundary changes to a state agency.

Legal Disputes

If the Census Bureau discovers that an area of land is in dispute between two or more
jurisdictions, the Census Bureau will not make any boundary corrections until the parties come
to a written agreement, or there is a documented final court decision regarding the dispute.
If you have questions concerning this, please contact the Census Bureau Legal Office at
301-763-9844.
For disputes involving tribal areas, the Census Bureau must defer to the Office of the Solicitor at
the Department of the Interior for a legal opinion. Often complicated land issues require an
extended period of time for resolution, and in those cases, the Census Bureau will retain the
current boundary in the database until a legal opinion is issued by the Solicitor’s office.

Respondent Guide Organization

PART 1: COMPLETING THE BAS FORMS
1.1

Forms Included in the BAS Package

The forms in the BAS package should be used to verify legal names, legal status, contact
information, previous legal boundary changes submitted to the Census Bureau, and to
document any recent or missing legal boundary changes. There are four types of forms:
1. BAS-1 for Incorporated Places
2. BAS-2 for Counties and Equivalent Areas
3. BAS-3 for Minor Civil Divisions (MCD)
4. BAS-5 for American Indian Reservations and Off-Reservation Trust Land

1.2

Name or Type Changes

Please verify that the legal names and legal status of the GU or AIA are accurate. Make any
necessary corrections by crossing out the error and clearly printing the correct information.
Provide an effective date for name, type, or status changes. County participants should verify
the list of active and inactive entities within their counties.

1.3

Contact Information

Please verify that the Census Bureau has the most recent BAS, HEO, or TC contact information
for the GU or AIA. Fill in any missing or incorrect information, especially blank e-mails. If the
primary address of the BAS contact, HEO, or TC is a PO Box, provide the Census Bureau with
a physical address that can be used for the delivery of maps. Contact changes or updates may
also be provided to the Census Bureau throughout the year by e-mail to [email protected].

1.4

Legal Boundary Changes

Please record all legal boundary changes in the Documentation of Changes section of the BAS
form. Include legal boundary changes that occurred prior to January 1 of the current survey
year if they do not appear on the current BAS maps. Please include legal authorization, such as
a local ordinance or resolution number, and the effective date of the legal action. If additional
pages are needed to record legal changes, a copy of the Documentation of Changes is provided
in the appendix.

1.5

Other Changes

Please indicate if there are any boundary corrections or feature updates that need to be made
on the BAS maps. This will assist the Census Bureau in identifying and accounting for any
updates made to the maps.

Boundary and Annexation Survey Respondent Guide: Paper

Page 1

PART 2: REVIEWING AND UPDATING THE BAS MAPS
Maps Included in the BAS package
The Census Bureau mails an index map showing the entire GU or AIA, along with more detailed
individual map sheets. Index maps are provided as a reference to help locate a map sheet. GUs
and AIAs with more than 30 map sheets receive only an index map and the map sheets that
show the legal boundary. Entities that require more than 30 boundary ring map sheets receive
only the index map.

Requesting Additional Maps
If you only received an index map for a county, incorporated place, MCD, or AIA where
boundary changes or feature updates need to be made, call (800) 972-5651 or e-mail
[email protected] to request an individual map sheet or a full set of maps. Do not make
updates on the index map.

General Guidelines for Reviewing and Updating BAS Maps
1. Colored pencils are provided in the package. The red pencil should be used to indicate
legal boundary changes and non-legal boundary corrections for all counties, places,
MCDs, and AIAs. The purple pencil should be used to indicate feature changes or
corrections. The blue pencil should be used by AIAs to add or modify tribal
subdivisions.
2. Compare the BAS maps to a local source for an entity (e.g., a local plat map, or a
county assessor’s dataset). Update the map(s) if the boundaries shown do not correctly
depict the boundaries in effect as of January 1st of the survey year.
3. You may also provide annexations and deannexations from previous years in addition
to providing updates as of January 1st. However, the Census Bureau does require legal
documentation when submitting these vintage legal updates.
4. The maps show boundaries for multiple legal and statistical boundaries. If an entity’s
legal boundaries are coextensive with another boundary, the symbols on the map will
alternate. In the figure below, the county shares a boundary with an incorporated place
and Census Designated Place (CDP); therefore, the symbols on the map alternate
between county, incorporated place, and CDP.

Figure 1. Shared Boundary

The combined line represents a county, incorporated place and
CDP boundary.

Boundary and Annexation Survey Respondent Guide: Paper

Census Bureau Geocoding
Geocoding is how the Census Bureau codes population to geographic entities. There are two
primary methods of geocoding used by the Census Bureau. Both of these involve coding an
address to a spatial polygon, but one uses Global Positioning System (GPS) technology, while
the other uses address ranges.

2.4.1

GPS Physical Location Geocoding

A field worker stands in front of a house or living quarters, and records the physical location with
a GPS device (Figure 2). Usually, the GPS point should fall very close to the front door of the
house. However, since this is a field operation, real-world obstacles like locked fences, poor
satellite reception, or even aggressive dogs might sometimes prevent the worker from gaining
access to the front door. In these circumstances, the worker may have to take the GPS
coordinate from the sidewalk or side of the road.

Figure 2. MSP Method of Geocoding

Notice in Figure 2. MSP Method of Geocoding that it is
occasionally not possible for the field worker to go all the way to the
front door, due to unforeseen circumstances, like the fence or the
dog shown above. Thus, the MSP (represented here in Figure 2 by
the red pins) can sometimes fall within the road or the road right-ofway.

2.4.2

Address Range Geocoding

When no Master Address File (MAF) structure point (MSP) is available, the Census Bureau
codes houses and living quarters according to a potential range of addresses associated with
the adjacent stretch of road (Figure 3).
Boundary and Annexation Survey Respondent Guide: Paper

Page 3

Figure 3. Address Range Method of Geocoding

While the two methods of geocoding differ greatly, both rely heavily on the integrated nature of
the MAF/Topologically Integrated Geographic encoding and Referencing (TIGER) System. The
representation of streets and boundaries relative to one another impacts these geocoding
methods. This interdependence between streets, boundaries, and geocoding means that
Census Bureau representations of legal boundaries occasionally differ from other
representations (e.g., in local or state GIS). This is especially true regarding geographic
corridors and offsets that follow road right of ways (or the front lot lines of parcels). In both of the
examples above, delineating a boundary along the front lot line will tend to increase the risk of
incorrect geocoding. Using the road centerline as a boundary eliminates these potential errors,
improving accuracy.

2.4.3

Completing a BAS Submission Using the Centerline of the Road

When completing a BAS submission in which a road or road right-of-way is owned or
maintained by a place or AIA but the adjacent housing is not, the respondent should use the
centerline of the road (not the front lot-line) as the boundary whenever possible. If local or state
law requires the use of the front lot line boundary, the respondent must explicitly designate the
polygon(s) between the road centerline and the front-lot boundary as a corridor or an offset (see
Section 3.9 of this document for more details).

Boundary and Annexation Survey Respondent Guide: Paper

Page 4

Legal Boundary Changes
Legal boundary changes are the result of legal actions (e.g., annexations), and documenting
such changes is the primary goal of the BAS. AIA legal documentation (e.g., statute, federal
court decision, trust deed) must accompany all AIA legal boundary changes, while legal
boundary change submissions from incorporated places, MCDs, and counties must provide an
authorization number, such as a resolution or ordinance number 1.

2.5.1

How to Draw Legal Boundary Changes

The following figures illustrate the correct way to draw legal boundary changes on BAS maps.
•
•
•
•

Using the red pencil provided, cross out the portion of the boundary that is no longer current with
a string of “Xs”.
Draw the new boundary line(s) ensuring the boundary is closed.
Add the ordinance number or other legal identifier of the action authorizing the change, along with
the effective date of each annexation or de-annexation that is drawn on the map.
Record all legal changes in the Documentation of Changes section of the BAS form.

Figure 4. Correctly Annotating a Legal Boundary Change
With the red pencil and record the changes in the Documentation of
Changes section of the BAS form.

Legal boundary changes from the State of Georgia are the exception: a state statute requires participants to include
acreage, and the Census requests that the respondent includes an authorization number.

Figure 5. Correctly Annotating an AIA Trust Land

Correctly annotate an AIA trust land and record the change in the
Documentation of Changes section of the BAS form. The original
reservation is not deleted and therefore does not require a string of
X’s.

2.5.2

Boundary Changes Involving Coincident Features

The following figures illustrate how to adjust a boundary that is coincident with
(i.e., follows exactly) a feature, such as a river or street. In this case, the feature location is
correct, but the boundary location is incorrect.
•
•
•
•

Using the red pencil, cross out the portion of the boundary that is no longer current using a string
of “Xs” inside circles.
Draw the updated boundary.
Add the authorization number or other identifier of the action authorizing the change along with
the effective date of each addition or deletion.
Record all legal changes in the Documentation of Changes section of the BAS form.

If both the boundary and feature need to be moved, cross out the incorrect boundary with a
string of red “Xs” and then draw a red line representing the new location of the boundary and
road.
Figure 6, Figure 7, and Figure 8 below illustrate how to make a correction to the boundary
where an associated feature moves along with the boundary. If these changes are the result of
an annexation or deannexation, include the authorization number and effective date.

Boundary and Annexation Survey Respondent Guide: Paper

where the river location does not change, but the boundary does.
The legal change is also recorded in the Documentation of
Changes.

Figure 7. Annotating a Legal Change to an Incorporated Place

Annotating a legal change to an incorporated place boundary
coincident with a road feature, where only the boundary moves to
the new location. The street feature location is correct, but the
boundary location is incorrect.

2.5.3

Boundary Corrections

A boundary correction is the adjustment of a boundary to correct an error in how the Census
Bureau depicts an existing boundary. Boundary corrections should follow the general shape of
the existing boundary. Legal documentation is not required when submitting a boundary
correction to the Census Bureau. Boundary corrections also do not need to be reported on the
BAS form.
Figure 8 illustrates how to complete a boundary correction.
Boundary and Annexation Survey Respondent Guide: Paper

Page 7

•
•
•

Using the red pencil, cross out the incorrect boundary with a string of “X”s.
Add a line showing the correct boundary.
Print the letters BC inside the change to identify the update as a boundary correction rather than
a legal change.

Figure 8. Annotating a Boundary Correction to an Incorporated Place Boundary

2.5.4

Tribal Subdivisions

The Census Bureau considers any type of unit of self-government or administration in tribal
areas as a tribal subdivision. A tribe may submit only one type of subdivision, even if it has
more than one type of distinct administrative area that could qualify as a tribal subdivision
(e.g., tribal election districts, tribal water districts, or health service areas with different
boundaries). The Census Bureau recognizes two types of tribal subdivisions, active (A) or
inactive (I):
•
•

Active subdivisions are defined as having a functioning government, with elected officials, that
provides programs and services.
Inactive subdivisions have no functioning government or elected officials and receive services
solely from the tribe.
a) Some examples of areas submitted as tribal subdivisions are:
•

Areas used by a tribe for the election of tribal government officials (e.g., districts or precincts
used for the election of tribal council members).

•

Areas used by a tribal government for tax purposes.

•

Areas used by a tribal government for the provision of general services or specified services,
such as:
o

Water districts;

Health service areas;

Emergency service delivery areas (911, fire, and/or police); or

Grazing districts or range units.

Historical or traditional areas recognized by a tribal government.

o Sub-reservation tribal community governments.
b) Keep the following criteria in mind when defining tribal subdivisions:
•

Tribal subdivisions should cover all, or most, of a tribe’s land base.

•

The delineation of tribal subdivisions is restricted to the area contained within reservations
and/or associated off-reservation trust lands.

Boundary and Annexation Survey Respondent Guide: Paper

Page 8

•

There is no minimum population threshold for a tribal subdivision.

•

A tribal subdivision may be noncontiguous.

•

Tribes may designate only one type of tribal subdivision. If a tribe has more than one level of
tribal subdivision within its land base, the Census Bureau recommends delineating
subdivisions corresponding to the lowest geographic level (those geographic areas
containing the smallest area) of the tribe’s administrative hierarchy.

•

Tribal subdivisions should not be based solely on land ownership or other cadastral areas,
nor should they consist of divisions based on the U.S. public land survey system of
townships, ranges, and sections, if these areas have no governmental or administrative
function for a tribe.

•

The following descriptions can be appended to chosen subdivision names (e.g., Red Rock
Community):
o

District.

Community.

Area.

Chapter.

Segment.

Administrative Area.

Addition.

County District.

3.1

Tribal Subdivision Program Procedures

If this is the first time that tribal subdivisions are being provided to Census:
•

Using the blue pencil, please add the boundaries on the BAS map(s).

Note: If a full set of BAS maps has not been sent, please request them by calling the Census Buraus’s
BAS team at (800) 972-5651.
•
•
•

Please note: each tribal subdivision must be labeled on each map sheet with its name (e.g.,
“District 3,” “Arlee District,” “White Rock Chapter,” “Parmelee Community”).
Record the names, type, and status of each subdivision in the Tribal Names and Status
Documentation section of the BAS-5 form.
If a tribal subdivision boundary follows a visible feature such as a stream, road, or fence line,
please be sure to indicate that on the BAS map. Add the visible feature the boundary follows if it
is not already shown on the map.

the Tribal Names and Status Documentation section of the BAS
form.

3.2

Updating Existing Tribal Subdivisions

If tribal subdivisions were delineated during a prior survey, they are symbolized on the enclosed
BAS maps by a dashed pentagon-shaped gold line.

Boundary and Annexation Survey Respondent Guide: Paper

Page 10

Before adding/or revising tribal subdivision boundaries on the enclosed map(s):
•
•

Using the red pencil, please note any changes to the boundary of the land base on the map(s).
Using the blue pencil, please add and/or revise the boundaries of the tribal subdivisions on the
enclosed BAS map(s).

Note: The names and types (active or inactive) of tribal subdivisions are listed in the Tribal Names and
Status Documentation section of the BAS-5 form. This information should be reviewed and
updated.

3.3

Tribal Subdivision Documentation

New tribal subdivisions and name changes to existing tribal subdivisions require documentation,
regardless of whether they are being delineated for the first time, or being added to those
previously reported. This documentation should be in the form of a tribal resolution or a tribal
constitution. Include a copy of this documentation with your BAS maps and BAS-5 form when
returning these materials to the Census Bureau.
Corrections to the Census Bureau’s depiction of tribal subdivision boundaries or names do not
require documentation.
If there are any questions or if additional maps are needed, please contact the Census Bureau’s
BAS team at the telephone number shown on the enclosed BAS-5 form.

3.4

Feature Modifications

The primary purpose of the BAS is to collect legal boundary information. However, please also
submit feature (e.g. streets, rivers) updates and modifications occurring near or coincident with
a legal boundary through the BAS. Feature modifications that are internal to the boundary of an
incorporated place, county or MCD will be accepted, but are not required as part of the BAS.

3.5

Modifying Locations of Streets

The following figures illustrate how to correct the location of a street feature:
•
•
•

Using the purple pencil, please cross out the incorrect feature location with “Xs”.
Please draw the feature in the correct location.
Please print the name of the feature along the length of the feature (as shown in the Figure 10
and Figure 11).

Figure 10. Modifying a Street Feature No Boundary Movement

Boundary and Annexation Survey Respondent Guide: Paper

Page 11

In this example the street location moves, but the boundary does
not.

Figure 11. Modifying a Street Feature with Boundary Movement

In this example both the street location and the boundary move.

The Census Bureau recently completed a nationwide program to improve the positional
accuracy of all streets and other features that appear in the Census Bureau’s MAF/TIGER
System. It is not necessary to make small positional corrections on the BAS maps; correct only
those streets that are incorrectly located, mislabeled or distorted. Additionally, new streets may
be added, and nonexistent streets may be deleted.

3.5.1

Adding, Deleting, and Naming Streets

When adding missing streets, new streets, and alternate street names:
•
•
•
•

Please use the purple pencil to draw the feature and its name on the map.
Where possible, please provide the address range for any new streets.
Please provide the MAF/TIGER Feature Class Code (MTFCC) (Appendix B) for all new streets
(Figure 12).
Alternate street names may be written in parentheses below the primary street name.

Figure 12. Adding an MTFCC Code When Adding a New Street

Boundary and Annexation Survey Respondent Guide: Paper

Page 12

Note: Due to the difficulty of showing multiple names for the same street, only the primary street name is
shown on BAS maps. Please note that, even though alternate street names are not shown on the
maps, they do exist in our database. For example, US Hwy 30 may be locally known as Main St.,
but on the BAS map, only US Hwy 30 will be displayed; however, within our MAF/TIGER System,
both names are listed. If you have reported an alternate street name in the past, you do not have
to report it to us again.

3.5.2
•
•

When Correcting Street Names:
Using the purple pencil, please draw a line through the incorrect street name.
Please print the correct street name along the feature.

Figure 13. Correcting a Street Name.

Note: If an area of the map is too congested to add all feature names, please number each feature and
list this number and the corresponding feature name in the map margin or in an uncongested spot
close to the feature’s actual location (Figure 14). Do not repeat numbers on a map sheet.

Figure 14. Adding Street Name Features in a Congested Area When Deleting Streets

Note: Delete street features only if they are nonexistent, or impassable. Do not delete a street because
the local jurisdiction is not responsible for maintaining it.
•
•

Using the purple pencil, please mark the beginning and end of the base feature to be deleted with
hatch (//) marks perpendicular to the feature as shown below.
Cross-out what is to be removed using a string of “Xs”.

Boundary and Annexation Survey Respondent Guide: Paper

Page 13

Figure 15. Deleting a Street Feature

3.5.3
•

When Naming Streets:
Using the purple pencil, please label any unnamed streets on the maps.
o

Label any unnamed private roads with PR; and

Examples of private roads are driveways and unnamed roads in commercial or industrial
parks.

Figure 16. Adding Unnamed Road Features

3.5.4

Adding a Cul-De-Sac or Circle

When adding a cul-de-sac or circle:
•

Using the purple pencil, please draw the feature.
o

Cul-de-sacs are entirely paved, and should be drawn as a solid dot; and

Circles have an area of unpaved ground within them, and should be drawn as an unfilled
circle.
Print the name of the associated street leading to the cul-de-sac or circle.
o

•

Boundary and Annexation Survey Respondent Guide: Paper

3.6

Annotating Address Range

Addresses are stored in the Census Bureau spatial database as potential address ranges. The
BAS maps show the break in the potential address range created where a street is bisected by
a boundary. These address range breaks are shown because it is important that the Census
Bureau assign the correct addresses to each governmental unit.
Note: Some streets on the BAS maps do not display address breaks due to space considerations.

Add address ranges on both ends of the street only if one of the following circumstances exists:
1. A road where house numbers, street names and/or addresses were added or deleted;
2. A street was added that crosses a boundary; or
3. The address ranges created by a boundary are incorrect on the map.

3.6.1

When Adding Address Ranges:

Using the purple pencil, please add in the address ranges, providing the lowest and/or highest
possible addresses where the road intersects a boundary (Figure 18).

Figure 18. Adding Street Feature/Annotating with Name and Address Breaks

Boundary and Annexation Survey Respondent Guide: Paper

Page 15

3.7

Point Landmarks

BAS maps display a select number of point landmarks (e.g., mountain peaks). Point landmarks
can be updated through the BAS, but are not required.
Acceptable point landmark feature updates include mountain peaks or summits, libraries, city
halls, community centers and police stations. Airports, parks, schools, golf courses, museums,
and cemeteries may be submitted as point landmarks or area landmarks.
Features that contain residences or private business should not be added as point landmarks or
area features (e.g. hotels, campgrounds, retirement homes, farms).
The BAS maps also include select point landmarks (e.g. airports, cemeteries, summits) taken
from USGS topography maps and the USGS Geographic Names Information System. These
landmarks represent the official federally recognized name and will not be removed or updated
without USGS verification.
When adding a point landmark:
•
•

Using the purple pencil, place a solid dot at the location of the point landmark.
Print the name of the landmark next to the dot.

Figure 19. Adding a Point Landmark

3.8

Area Landmarks

The BAS maps display a select number of area landmarks (e.g., lakes). Like point landmarks,
area features can be updated through the BAS, but are not required.
Acceptable area landmark updates include water bodies, swamps, quarries, national parks or
forests. Airports, parks, schools, golf courses, museums, and cemeteries may be submitted as
area landmarks or point landmarks.
Features that contain residences or private business should not be added as point landmarks or
area features (e.g. hotels, campgrounds, retirement homes, farms).
When adding an area landmark:
•
•

Using the purple pencil, draw the area landmark boundary in the correct location.
Print the name of the landmark inside or next to the feature.

Boundary and Annexation Survey Respondent Guide: Paper

Figure 20. Adding an Area Landmark

3.9

Geographic Corridors and Offsets

A geographic corridor is an area that only includes road surface and right-of-way and does not
contain any structures addressed to either side of the street. A geographic offset is an area
claimed by a geographic entity that is only on one side of a road and does not include structures
addressed to that side of the road.

Figure 21. Geographic Offset and Geographic Corridor

The image on the left illustrates a geographic offset, designated by
red diagonal lines. The offset is part of the incorporated place
(green area). However, the dwelling units are counted outside of
the incorporated place. The image on the right illustrates a
geographic corridor (Co Rd, south of Samples Rd) and a
geographic offset (Co Rd, north of Samples Rd). The geographic
corridor and offset are both part of the incorporated place (yellow
area), but dwelling units are not.

3.9.1

Geographic Corridors

Figure 21 shows a corridor that has been created where the incorporated place or AIA owns the
right-of-way, and wishes for that ownership to be displayed on the Census Bureau’s maps, but
the housing units are not included in the incorporated place or AIA (shown in color). Without a
corridor, the housing units along this road would be incorrectly geocoded into the incorporated
place or AIA. Thus, if it is important to the place or AIA that its ownership and/or maintenance of
the road and/or its rights-of-way be displayed on Census’ maps, a geographic corridor should
be created. However, the Census does not require places and AIAs to report rights-of-way:

Boundary and Annexation Survey Respondent Guide: Paper

Page 17

maintaining geographic corridors in a nationwide database is not essential to the mission of the
Census Bureau and the right-of-way should only be included if it is crucial to the place or AIA, or
if state or local laws require it.
Figure 22 below shows a case where the right-of-way belongs in the unincorporated area, while
the housing units in Figure 23 are included in the incorporated place (shown in color). While
depicting this corridor may be important for local purposes, it is not relevant for Census Bureau
tabulations because no house can be built in a road right-of-way. This type of corridor should
not be included in a BAS response.
Please note that the Census Bureau does not require places or AIAs to display rights-of-way or
road maintenance corridors that do not contain or potentially contain housing or population. If
local or state law does not require depiction of these geographic features, the Census Bureau
prefers that they be left off BAS submissions. If it is necessary for the place or AIA to depict
them, they must be submitted as a geographic corridor.

Figure 22. Where the Right-of-way Belongs in the Unincorporated Area
Figure 23. Housing Units in the Unincorporated Area

Geographic corridors can be provided to the Census Bureau if the centerline representation
results in addresses being assigned to the wrong entity. However, geographic corridors should
only be created if the addresses along the street do not belong to your governmental unit. To
indicate a geographic corridor on your map, use the red pencil to draw a line on each side of the
road. Mark the beginning and end of each line with perpendicular hatch marks. Write the letters
“GC” beside each line (Figure 24). To remove a geographic corridor or offset, use the red pencil
to mark the beginning and end of the corridor or offset with perpendicular hatch marks and write
“remove GC.”

Boundary and Annexation Survey Respondent Guide: Paper

Page 18

Figure 24. Indicating a Geographic Corridor by Using a Red Pencil

To indicate a geographic corridor on your BAS return, use the red
pencil to draw a line on each side of the road. Mark the beginning
and end of each line with perpendicular hatch marks. Write the
letters “GC” beside each line.

3.9.2

Geographic Offsets

The Census Bureau is aware that many governments base their legal boundaries on cadastral
(parcel-based) right-of-way mapping. The Census Bureau bases their maps on spatial data that
is topologically integrated. This makes the maintenance of geographic offsets inefficient.
Delineating an entity boundary on the centerline wherever applicable will help to establish more
accurate population counts. If a boundary is on the front lot line adjacent to a road on the map,
the Census Bureau strongly prefers that the boundary be delineated on the road centerline
already shown on the map. If a boundary is on the rear or side lot line, then it should be
depicted as such. If it is unclear whether a particular line is a front lot line or something else,
please contact the BAS team for assistance. Generally, if a house or other building could not
conceivably be built in the area between the potential line and the centerline of the road, then
the line can be considered a front lot line.
Figure 25 shows a situation in which the place boundary is along the front lot line. In this
example, the respondent must either delineate the boundary on the road centerline, or create an
offset. In Figure 26, the place boundary is on the rear lot line, so the respondent should not
delineate it on the road centerline or create an offset; instead, the respondent should delineate a
new edge that actually follows the rear lot line.

Boundary and Annexation Survey Respondent Guide: Paper

Page 19

Figure 25. The Place Boundary is Along the Front Lot Line
Figure 26. The Place Boundary is on the Rear Lot Line

To indicate a geographic offset on your map, use the red pencil to draw a line parallel to the
road, along which you want the offset to be created. Mark the beginning and end of the line with
perpendicular hatch marks. Write the letters “OFF” on the side of the road where the geographic
offset exists (Figure 27).

Figure 27. Depicting a Geographic Offset on a Paper Submission

3.10

County Review and Consolidations

Counties receive boundary information from the Census Bureau for all governmental units within
their county boundary. Counties should review the names and legal status of active and inactive
incorporated places and MCDs found on page 3 of the BAS-2 form.
•
•

Active entities are defined as having a functioning government, with elected officials, that
provides programs and services.
Inactive entities have no functioning government or elected officials, receive services solely from
the county, and should be reviewed by the county during BAS.

Boundary and Annexation Survey Respondent Guide: Paper

Page 20

Although it is not required, counties may update boundaries for incorporated places and MCDs
on the county BAS maps. The Census Bureau encourages counties to establish Consolidated
BAS agreements with local governments in order to consolidate resources, reduce the burden
on local governments, and avoid duplication of work. Under a Consolidated BAS agreement, the
county is responsible for reporting boundary changes to the Census Bureau. Participating local
governments would no longer receive an annual BAS package. One hundred percent
participation is not required and governments may opt out of the agreement at any time. Contact
the Census Bureau at for more information on participating in a
Consolidated BAS (CBAS) agreement or visit the Consolidated BAS website at

3.11

Public Land Survey System

Boundaries are often based on nonvisible features, such as Public Land Survey System (PLSS)
lines (i.e. township, section, range lines, etc.). The Census Bureau is currently working on a
program through which PLSS lines can be incorporated into the MAF/TIGER System. If any of
your entity’s existing or new boundaries are known to follow PLSS lines, you should designate
that on your BAS submission by writing “PLSS” in red pencil next to (and parallel to) the
appropriate boundary segments. In areas where the Census Bureau has obtained accurate
PLSS shapefiles, we will then be able to compare these lines to those shapefiles and ensure
accurate placement of the boundary.

3.12

New Incorporations

Newly incorporated places should provide the Census Bureau with:
•
•
•

3.13

A copy of the official new incorporation papers, including date of incorporation;
A map indicating the boundaries of the new incorporation; and
Contact information for the highest elected official and a contact for the BAS.

Disincorporations

Disincorporated entities should provide the Census Bureau with a copy of the official papers of
disincorporation, including the effective date.

READING A MAP
C1

Scales

A map is a paper or digital representation of an area. Naturally, the map is always smaller than
the area it represents, so nearly all maps are equipped with a scale, which depicts the ratio of
distance on the map to the actual distance on land. The scale can be designed any number of
ways, but two of the most common scales are ratio scales (Figure C1), which describe a ratio
between the map and the real world (e.g., 1: 24,000), and bar scales, which depict that
relationship graphically by displaying how much a certain distance on the map represents in the
real world (Figure C1). In other words, if a map has a ratio scale of 1: 24,000, it means that one
inch on the map represents 24,000 inches on the ground. (This works with any unit of
measurement, so long as the unit being used on the map is the same as – or properly converted
from – the unit being depicted on the ground.) Often a map will have both types of scale.

Figure 29. Bar Scale

The map from which this scale was taken has a ratio scale of
1:15,000. The bar scale shows distances in kilometers and miles.
A bar scale will often be a set length (e.g., one inch), and/or represent a set distance (e.g., one
mile). You can use the bar scale to determine distance on your map by using a ruler. Simply
place the ruler on the map to determine the distance on the map; then place the ruler along the
bar scale, which will show how much that distance represents on the ground.
Maps that display a small area, but with a relatively large amount of detail, are considered largescale maps (see Figure C2). A map that displays a large area, but shows less detail, is called a
small-scale map (see Figure C3). This is because the representative fraction of a large-scale
map (e.g., 1/7,500 or 1:7,500) is a larger fraction than that of a small-scale map (e.g., 1/250,000
or 1:250,000).

Figure 30. Large Scale Map

A large-scale map shows a greater amount of detail; this example
displays streets, parks, churches and restaurants.
Boundary and Annexation Survey Respondent Guide: Paper

Page C-1

Compass Rose

All maps should have some sort of diagram depicting at least one – but sometimes all – of the
cardinal directions (north, south, east, and west) that the map reader can use to orient the map.
This diagram is sometimes called a compass rose (see Figure C4). A compass rose can have
any number of designs, and north can be shown in any direction on the map, but most maps are
oriented with north at the top of the map. It is important to check the compass rose when
beginning to read a map, in order to determine the direction in which the map is oriented (i.e.,
which direction is at the top of the map).

Figure 31. Compass Rose

Legend

Because a map is a graphic representation of a real-world area, naturally, it is necessary, and
convenient, to symbolize real world features with representative symbols. These symbols can
take any form, so long as they are consistent within any individual map. In order to describe
what each symbol means, most maps have a legend (see Figure C5). The legend is typically
located on the side or bottom of the map – they can be anywhere, so long as they do not
obstruct the integral parts of the map. Typically, the legend will have a small example of each
symbol (e.g. a line, or a picture of a tent), and next to the symbol, in text, a brief description of
what is being depicted (e.g. “road”, or “campground”).

Figure 32. Legend Describing What Each Symbol Means

Sometimes a map needs to depict multiple features concurrently. This is because some lines
are the boundaries of multiple geographies at the same time (i.e. a county boundary can also be
a city boundary, a voting district boundary, and even a highway or river). Such instances can be
depicted in various ways, but Census Bureau maps depict coincident lines by alternating the
symbols for each type of line as shown in Figure C6 below. In other words, if a line is both a
county boundary (symbolized by a series of squares) and a city boundary (a series of circles),
Boundary and Annexation Survey Respondent Guide: Paper

Page C-2

that boundary will be depicted as a series of alternating squares and circles for the length of the
concurrency.

Figure 33. Map Depicting Multiple Features Concurrently

In this case, the city and the county boundaries are coincident, and
run through the middle of the river.

In situations where higher-level geographies (e.g. national, state, county, or county
subdivisions) coincide, the Census Bureau’s maps display only the symbol of the highestranking of these boundaries. In other words, if a particular boundary is shared by both a state
and county, only the symbol representing the state boundary will be displayed.

Index Maps

In order to decide which map you need to use for your BAS submission, it is necessary to view
the entity as a whole, and choose the correct parent map sheet based on its location within the
entity. You can do this by referring to the index map (Figure 34), a relatively small-scale map
that shows the entire entity, and the location and number of all parent map sheets within that
entity. Each parent map sheet has a numerical locator which differentiates it from the other
parent map sheets associated with that entity. The numbering begins with the northern and
western-most parent map sheets, and continues left-to-right, in much the same pattern as words
in a book. By referring to the index map, you can then determine which parent map sheet(s) you
need to use for your BAS submission, and then access it based on its number on the index
map.

Boundary and Annexation Survey Respondent Guide: Paper

Page C-3

Figure 34. Index Map

The Index Map sheet shows the location of all parent map sheets
and inset map sheets within an entity.

The index map is not appropriate for BAS submissions. Its purpose is as a reference or index of
parent maps, and it will not be accepted as a BAS submission.

Inset Maps

In some instances, in highly congested areas, even a parent map sheet provides insufficient
detail for BAS purposes. In such cases, rather than using a parent map, the area is depicted
within an inset map (Figure 36). This refers to a map with a very large scale, so that it displays
a smaller area than the parent map sheet, but with greater detail. On the index map, an inset
map is represented by a green outline, and is assigned a number preceded by a letter (i.e. A1,
A2, B1, etc.), as shown in Figure 35 on the next page. Inset maps are only found in areas with
a large number of features, and as such are used less often than parent maps.

Boundary and Annexation Survey Respondent Guide: Paper

Page C-4

Figure 35. An Inset Map as it is Displayed on the Index Map

Figure 36. Inset Maps

Inset maps show areas of relative congestion at a large scale,
allowing a greater amount of detail.

Parent Maps

Many entities 2, such as incorporated places and counties, are too large to be shown on a single
map; that is, the scale is too small to allow the necessary details for BAS updates. Thus, it is
necessary to separate the entity into sections, each of which has its own map, called the parent
map sheet 3 (Figure 37). Thus, a single entity is often represented with numerous map sheets,
with each parent map sheet showing a small section of the entity. Each parent map is assigned

Entity refers to any local governmental unit, e.g. a county, incorporated place, or minor civil division.

3Within

the scope of BAS, the terms ‘map’ and ‘map sheet’ have the same meaning, and they are used
interchangeably throughout this document.

Boundary and Annexation Survey Respondent Guide: Paper

Page C-5

a number, beginning with the number one and increasing progressively for each additional
parent map sheet (i.e. 1, 2, 3, 4, etc.). In this way, viewing and editing map sheets becomes
more manageable, and it becomes possible to depict an area with the level of detail necessary
to make changes or challenges. In most instances, the parent map is the one that should be
used for BAS submissions.

Figure 37. The Parent Map

The parent map sheet shows a section of an entity at a relatively
large scale.
In the bottom right-hand corner of the parent map sheet, there is a key to the parent map
sheet’s location in relation to adjacent map sheets as shown in Figure 37 above. A larger
example of this key is shown in Figure 39. This way, if you need to refer to an adjacent map
sheet, you can quickly determine which one you will need.

Figure 38. The Key to Adjacent Sheets

The key to adjacent sheets shows where the parent map sheet lies
in relation to adjacent sheets.
Boundary and Annexation Survey Respondent Guide: Paper

Page C-6

Next to the key to adjacent sheets, there is a small outline of the entire entity (the inside of
which is colored yellow), and a blue outline of the parent map sheet. This key displays the
location of the map sheet in relation to the entity as a whole as is shown in Figure 39 below.

Figure 39. The Sheet Location within Entity key

The sheet location with entity key shows where the parent map
sheet is located within the entity to which it belongs.

Receiving the GUPS Application and Shapefiles

GUPS is available for installation two ways. GUPS is available for download directly from the
BAS Web site . You can also request to receive GUPS on DVD, which will be shipped to you
in a package containing the GUPS DVD, respondent guide, and a read me text file.
Once you have installed GUPS on your computer, the BAS shapefiles can be imported from the
BAS Web site directly to the GUPS application. Instructions on how to load data into GUPS

Part 2: How to Use GUPS of this guide contains directions for how to use the tools available
within the GUPS application, as well as step-by-step instructions for how to carry out specific
shapefile updates (e.g., annexations and deannexations, adding and deleting features and
landmarks, etc.).
Embedded within the GUPS application (under the Help tab menu) are other resources,
including a short training video on how to submit a ZIP file through SWIM. Additional videos will
be provided on the BAS Web site as they become available. In addition, a Section 508compliant version of this guide is available there. The Help menu provides a link to both.
For supplemental information on functions within GUPS that are specific to QGIS, a QGIS
user’s manual can be found at . The
QGIS manual offers particularly helpful information on several activities that are touched on in
this guide, but not described in detail, including working with user-provided data layers, creating
search expressions for attribute tables, and creating customized coordinate systems. For
questions concerning technical problems with the GUPS application, user support is available

REVIEWING BAS DATA
The Census Bureau requests that you review and update all legal entities and boundaries within
your reservation/trust lands/tribal subdivisions, including the additions and deletions of land area
and boundary corrections. You may also update linear features and landmarks, including area
landmarks, hydrographic areas, and point landmarks, although review of these is optional.
To help conduct your review, the GUPS application will allow you to import and overlay your
own geospatial data layers with the Census Bureau shapefiles. You can import image files from
web mapping services, geodatabases, and also other file types. Steps to import the most
common types of user-provided data are provided in Section 5.7: How to Import UserProvided Data into GUPS.

2.3

Reviewing Legal Boundaries

The following can be updated through Tribal BAS:
•

Federal American Indian Reservations are areas that have been set aside by the United States
for the use of tribes, the exterior boundaries of which are more particularly defined in the final
tribal treaties, agreements, executive orders, federal statutes, secretarial orders, or judicial
determinations.

Trust lands may be located on or off a reservation; however, the Census Bureau tabulates data
only for off-reservation trust lands. Please do not submit on-reservation trust land because the
Census Bureau can only show the exterior reservation boundary.
•

Federal Off-Reservation Trust Lands are areas for which the United States holds title in trust
for the benefit of a tribe (tribal trust land) or for an individual American Indian (individual trust
land).

The Census Bureau does not identify fee land (or land in fee simple status) or restricted fee
lands as specific geographic areas.
•

Tribal Subdivisions are legal administrative subdivisions of federally recognized American
Indian reservations and off-reservation trust lands and are described as additions, administrative
areas, areas, chapters, county districts, communities, districts, or segments. These entities are
internal units of self-government or administration that serve social, cultural, and/or economic
purposes for the American Indians on the reservations and off-reservation trust lands.

•

Hawaiian Homelands are areas held in trust for Native Hawaiians by the state of Hawaii,
pursuant to the Hawaiian Homes Commission Act of 1920, as amended.

•

Alaska Native Regional Corporation (ANRCs) were created pursuant to the Alaska Native
Claims Settlement Act (ANCSA) enacted in 1971 as a "Regional Corporation" and organized
under the laws of the state of Alaska to conduct both the for-profit and non-profit affairs of Alaska
Natives within a defined region of Alaska.

Page 4

The following changes require documentation:
•

New off-reservation trust land;

•

New reservation land;

•

Changes from off-reservation trust land to reservation land and changes from reservation land to
off-reservation trust land;

•

Large changes to existing off-reservation trust land;

•

Large changes to existing reservation land; and

•

Boundary corrections to off-reservation trust land or reservation land that do not follow the
general shape of the boundary.

For off-reservation trust land, the most common documentation is a trust deed or a letter from
the BIA. Documents should state that the land is “in trust” for your tribe.
For reservation land, documentation examples include (but are not limited to) federal register
notice, Act of Congress, Executive Order, or a new legal opinion issued by the BIA. When
submitting large boundary corrections to an existing reservation, please submit your reservation
document.
If you cannot locate your documentation, you can contact your regional BIA office to obtain
documentation. The Census Bureau will treat legal opinions issued in writing from the BIA as
documentation since the BIA is the authority on reservation and off-reservation trust land
boundaries. If the Census Bureau cannot interpret a document, such as a treaty, the Census
Bureau will contact the BIA for assistance.
If you have questions about documentation, please call the Census Bureau at
1-800-972-5651 or e-mail [email protected]. If you need to contact the BIA, please see
for contact information for your
regional office.

2.5

Legal Disputes

If the Census Bureau discovers that an area of tribal land is in dispute between two or more
jurisdictions, the Census Bureau will not make either annexations or boundary corrections until
the parties come to a written agreement, or there is a documented final court decision regarding
the matter/dispute. If you have questions concerning this, please contact the Census Bureau
Legal Office at 301-763-9844.
For disputes involving tribal areas, the Census Bureau must defer to the Office of the Solicitor at
the Department of the Interior for a legal opinion. Often complicated land issues require an
extended period of time for resolution, and in those cases, the Census Bureau will retain the
current boundary in the database until a legal opinion is issued by the Solicitor’s office.

2.6

Reviewing Linear Features

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 5

likely to possess new or altered linear features (e.g., new subdivisions, traffic circles converted
to straight ways, or privately maintained roads that serve as public streets, but exclude private
driveways).
You may also add attribute updates (e.g., name, class code, and address ranges) for selected
features. For a complete list of MAF/TIGER Feature Class Codes (MTFCCs), review
Appendix C: MTFCC Descriptions.
To aid in the review of linear features, GUPS allows you to import local street centerline files,
hydrography layers, imagery, and other user-provided geospatial data for reference and
comparison against the Census Bureau data.
In your review, please note:
•

S1100 and S1200 – If you add road features with an MTFCC of S1100 (Primary Road) or S1200
(Secondary Road), you must supply a feature name. As is the case for all road features, the
feature name should be a proper name or route number.

•

Spatial Inaccuracies – The Census Bureau will not process the wholesale spatial realignment of
features to enhance spatial accuracy. If a feature is in the incorrect location, delete the feature
and add it in the correct location. Take this action only if the feature is exceedingly spatially
inaccurate and/or the current location (with respect to other features and boundaries) affects the
tabulation of housing units to the correct geography, such as legal entities, census tracts, and
census blocks.

•

Address Range Changes – The Census Bureau accepts address range data as part of the
linear feature update layer. As with other linear feature updates, you must supply the required
attributes and corresponding change type for the update. In addition, because existing address
ranges are not shown in our outgoing shapefiles, we recommend that participants only add
address ranges to new features.

2.7

Reviewing Area Landmarks and Hydrographic Areas

Add new area landmark or hydrographic area;

•

Remove area landmark or hydrographic area;

•

Change or add landmark name; and

•

Boundary corrections (add and remove area).

If you add a new area landmark or hydrographic area, please add only:
•

Water bodies;

•

Glaciers;

•

Airports;

•

Cemeteries;

QUALITY CONTROL AND FILE SUBMISSION
3.1

Validating Updates

Once you have completed your BAS updates, you must complete a review of your change
polygons to ensure that:
1. The polygons have no unintended holes (e.g., you annexed several faces but missed a traffic
circle or small pond).
2. All boundary corrections meet a minimum size threshold (very small corrections cannot be
processed).
Validate Often
Validation tools in GUPS can be accessed at any time while you are working in the application. We
suggest you utilize them as you work to identify errors early and avoid extensive rework. Steps to
use the Geographic Review tool and the Review Change Polygons tool are included in Section
6.5: How to Use GUPS Review and Validation Tools.

USING GUPS (BASICS AND MAP
MANAGEMENT)
After successfully installing GUPS, you are ready to start your BAS updates. There are three
ways to retrieve shapefiles when starting a new project:
•

From the Census Web site (loads directly into GUPS);

•

From DVD (If one was requested); and

•

From My Computer (if you downloaded them to your hardrive)

Table 6 shows the steps to open GUPS and start a new project using the Census Web site.
Table 7 shows the same steps to open GUPS, but starts a new project using the Census
provided DVD or My Computer (downloaded Census shapefiles saved to your hard drive).

5.1

How to Access BAS Shapefiles

BAS shapefiles from the BAS Web site can be pulled directly into the application when working
in GUPS. Users can load the shapefiles as needed or load multiple county files at once. This is
the preferred method for loading the Census Bureau’s BAS Shapefiles into GUPS as it ensures
that required files are placed in the correct location for the application to access.
Another option for loading files is to download the shapefiles to your hard drive from the BAS
Web site (or from the Census Bureau ftp2 site), then import them into GUPS. BAS shapefiles
are also available for download from the BAS Web site here:
.
Instructions for how to download Census Bureau shapefiles to your hard drive appear in Table 6
and Table 7. Downloading files to your hard drive is not the preferred method when working in
GUPS, and should be used only when necessary (e.g., you need additional data layers that
GUPS does not automatically load and want to pull them in as user-provided data).
If you have requested to receive the shapefiles on DVD, you can also load the files directly into
GUPS from the DVD. Instructions for how to load shapefiles are contained in Table 6: Start a
New Project Using Shapefiles from the BAS Web site.
Whether the files are pulled from the BAS Web site or from the DVD, the GUPS application
unzips them and places them into a pre-established folder created on your computer’s home
directory during the installation process (C:\GUPSGIS\gupsdata\BAS2018\shape). It then
displays them in the application. GUPS then manages the files for you. You do not need to take
any further action.
CAUTION!
Regardless of the source of the shapefiles, it is important that you DO NOT CHANGE any shapefile or
folder name. The files and folders must have the exact names given for the GUPS application to
recognize and load them.

This example uses Reservation/Trust Land.
Step 8

Next select the Entity Name field drop-down. Since you selected the entity type
‘Reservation/Trust Land’ GUPS automatically provides a list of the Reservations and OffReservation Trust Lands. The scroll bar to the right allows you to move up and down the list
of reservations/trust lands.

Step 9

Once you have selected your entity from the drop-down menu, the Map Management screen
will provide you with a list of counties. The counties in which the selected entity already exists
will be at the top of the list and their corresponding check boxes will be ‘checked’. Adjacent
counties (counties whose borders touch the automatically selected county or counties) are
highlighted in YELLOW. Any previously selected counties will be highlighted in CYAN.
All checked counties will display in the Map View. Uncheck the box for any county you do not
wish to see.

Page 27

Step

Action and Result

If you share a computer with other GUPS users, multiple project files may appear in the dropdown menu, as shown below. Here three separate users in Karuk Reservation have created
projects on the same computer.

To identify which of the entries in the list represents your project, look at its number string.
This string comprises your BAS ID. Each BAS ID is 11 digits. The first digit indicates the Entity
Type (i.e., the user type) (4 = American Indian Area). The next two digits are the state FIPS
code and 99 is what BAS uses for all AIAs since they can cross state lines. The following four
digits are the TR code (the tribe code). The final four digits are the AIANNHCE/TA Code (the
tribal area code).
The number string,
reflects a project created by the Karuk Tribal
participant , where 4 = American Indian Area; 99 = state FIPS code used for tribal areas; 0117
= code for Karuk Tribe ; and 1760 = Karuk Reservation/Trust Land.
If you do not know the BAS ID information for your particular geography, it is available within
the Map Management dialog box. Below is an example for Karuk Tribe Karuk Reservation.

Step 20

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

The limit to how many county datasets can be loaded at once is 11 (the working county plus
10 other counties). To load shapefiles for additional counties, after the first 10 are loaded:
•

Leave the same working county selected in the Working County field.

•

Uncheck the already loaded counties in the Map Management dialog box list.

How to Update Legal Boundaries

6.1.1

Adding Land Area as Reservation or Trust Lands for the First Time

Follow the steps in Table 25 to add land as reservation or off-reservation trust land(s). In this
example, we will add a parcel of land as a fictitious newly acquired ‘off-reservation’ trust land for
the Spirit Lake Reservation (3935).
Table 25: Add Land Area as Reservation or Off-reservation Trust Land
Step

Action and Result

Step 1

Open in Map View the entity where you want to add the new trust land(s). Be sure that you
have all layers you wish to see checked in the Table of Contents. It is recommended that you
check (turn on) all Tribal Layers.

Step 2

Click the Modify Area Feature button on the BAS toolbar.

The Modify Area Feature dialog box opens.

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 63

Step
Step 3

Action and Result
Click the drop-down arrow next to the Geography field, and select the entity type you want to
add from the drop-down menu. In this example we are adding a Off-Reservation trust land, so
we select ‘Reservation/Trust Land’.

Reservation/Trust Land appears in the Geography field and prior to any changes, Spirit Lake
Reservation will be the only file that becomes available.

Step 4

Step 5

Then click on the map to select the face or faces.
If the entity includes only a single face, you may simply click once on the face to select it. If the
entity includes several contiguous faces, after clicking on the first face, depress the CTRL key
and while holding it down, left-click on each additional face to be added. The selected faces
turn cyan (colors may vary).

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 64

Step

Action and Result

Note: You may also select faces (after clicking the Select Features button) by simply
dragging your cursor over the edges that mark their boundaries. Additional means of selecting
faces (by polygon and by radius) are discussed in Table 14 in Section 5.
Because all geographic areas consist of faces, you may need to “split” a face to accurately
reflect an entity’s boundary.
To split a face, digitize a new line that represents the boundary’s location (see Table 29 for
instructions to add a linear feature) and assign it the appropriate MTFCC. This splits the
original face into two faces. You can now select the face you need to add to the new entity.
Step 6

To record a new entity, click the Add Entity button on the dialog box toolbar.

The Modify Area Feature new entity dialog box opens.

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 65

Step

Action and Result

If you click the Add Entity button before selecting the faces, you will see a pop-up box
warning. Simply click OK and add the faces.

Since we have already selected faces, we do not see the pop-up warning.
Step 7

In the new entity dialog box, select the LSAD (Legal/Statistical Area Description) from the
drop-down list available. In this example, we will indicate that it is an ‘Off-Reservation Trust
Land (suffix)’ since a reservation already exists. If a reservation didn’t already exist, then the
LSAD should be ‘Trust Land (suffix)’. The term ‘Off-Reservation Trust Land’ or ‘Trust Land’ will
be added to the Entity Name, in this example, will be added to Spirit Lake Reservation.

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 66

Step
Step 8

Action and Result
Next add the effective date for the legal change. Click on the calendar icon next to the
EFF_DATE field and, when the calendar opens, click on the effective date.

The date selected populates the EFF_DATE field.

Step 9

Next, add the authority type using the AUTHTYPE drop-down menu. In this example we have
indicated the AUTHTYPE as a D-Deed.

Step 10

Finally, upload documentation for the change. For all changes that are more than cartographic
boundary corrections, documentation will need to be provided. To upload documentation, click
the folder icon next to the DOCU field.

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 67

Action and Result

The DOCU window opens.

Step 11

Click on the icon for ‘My Computer’ (or simply ‘Computer’ in some Windows versions) to open

Click the OK button.
Note: Red asterisks indicate required fields. You must complete required fields to move
forward. If you click OK and have not completed one or more required fields, GUPS will
prompt you to do so. Any required field not completed will highlight in red
If your reservation and/or trust lands contain more than 1 census tract, or more than 1
block group or more than one Tribal Subdivision – there are a few additional steps –
continue on to Step 15 below.

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 69

Step

Action and Result
If not, and you have completed all required fields, when you click OK, the faces for the new
entity turn green on the map (colors may vary) and the name of the new entity appears on the
list in the Modify Area Feature dialog box. Skip to Step 16.

Once the Census Bureau verifies the new Trust Lands, it will assign it the same FIPS code as
the Reservation.
Step 15

If you have more than 1 census tract, block group or tribal subdivision, there are additional
steps to follow when adding area either as ‘reservation’ or ‘trust land’.
After clicking OK (in Step 14) if there is currently more than 1 tribal subdivision defined for the
Entity, a pop-up window will appear with a drop down menu to select which Tribal subdivision
(AITSL) the new area should be assigned too. In this example, the new Off-Reservation Trust
Land is being assigned to Wood Lake District (80).

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 70

Step

Action and Result
Once a selection is made, if there is more than 1 Tribal Block Group (TBG), a new pop-up
window will appear with a drop-down menu to select which Tribal Census Tract/Tribal Block
Group to which the new area should be assigned. In this example, it is being assigned to the
adjacent area labled 3935T00100B.

Once the selection is made, you are returned to the Modify Area Feature menu and can
continue with additional changes to the boundaries. (Step 16)

Step 16

To make additional changes to the map, simply make a new selection in the Modify Area
Feature dialog box Geography field and continue work (refer back to Step 3 above). You
may save your changes as you go or wait until you have finished all work on the map. Saving
as changes are completed, however, is recommended to avoid losing work in the event of a
power outage or system interruption. Changes can be made to the reservation boundary, trust
land boundaries and tribal subdivision boundaries.

Click on the Zoom in button on the Standard toolbar to zoom into the area where the
addition is to be made.

Step 6

To select the faces you want to add to the off-reservation trust lands, click on the small down
arrow next to the Select Features button on the dialog box toolbar. The Select Features
button drop-down menu opens.
In this example we will use the “polygon” method to select the faces we want to add to
Kootenai Off-Reservation Trust Lands. Click on ‘Select Features by Polygon’ in the menu.

Step 7

Next, go to the map and place your cursor where you want to add the faces.

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 73

Step

Action and Result
To select a single face, simply drag the cursor outward in the center of the face. To select
multiple faces, drag the cursor across the edges that separate the faces. In this example, we
select seven faces. The faces selected turn cyan (color may vary).

Because all geographic areas consist of faces, you may need to “split” a face to accurately
reflect an entity’s boundary. To split a face, digitize a new line that represents the boundary’s
location (see Table 29 for instructions to add a linear feature) and assign it the appropriate
MTFCC. This splits the original face into two faces. You can now select the face you need to
add to the new entity.
If you accidentally select a face you do not wish to include, you can use the Deselect
Features from All Layers option in the Select Feature(s) drop-down menu to clear the
selected faces from your screen and start over.

Step 8

Click the Add Area button on the dialog box toolbar.

How to Use GUPS Review and Validation Tools

GUPS provides two tools—the Geography Review tool and the Review Change Polygons
tool to help you review and validate the updates you have made in the system.

6.5.1

Geography Review Tool

The Geography Review tool filters the map layers based on various fields in the attribute table.
You can use this tool to check the changes you made to linear features, area landmarks, point
landmarks, and legal boundaries anywhere within your project area (you may also view the
attributes of entities, features, landmarks, and boundaries you did not change). Note: Although
this tool allows you to review your changes, you cannot use it to edit them.
Instructions for how to use the Geography Review tool information appear in Table 40 below.
Table 40: Use the Geography Review Tool
Step
Step 1

Action and Result
Click on the Geography Review button on the BAS toolbar.

The Geography Review Tool dialog box opens.

Step 2

In the Layer Name: field drop-down menu, select the data layer you want to view:

In this example, we selected the file “bas17_49901171750_99_changes_aial.” This is the
transaction data output file for the tribal areas layer (note the word “changes” in the file
name to indicate the layer has been updated).

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 106

Step
Step 3

Action and Result
Once you make your selection, the attribute table for the layer opens, with the attributes for
each tribal area you changed displayed in a separate row.

If you cannot see all the columns in the attribute data table, drag the edge of the dialog box
outward to widen the view. You may also move the dialog box to another location by
clicking inside the box and dragging it. For example, this particular table consists of 24
fields (columns). You can expand the table or use the scroll bar at the bottom of the screen
to scroll right and left.
Step 4

To see a tribal area on the map, click its row in the attribute table, then click the Zoom
button (the row is highlighted and the map automatically zooms to the area selected, which
is highlighted and shows changes made in cyan – colors may vary).

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 107

Step

Action and Result

Step 5

To view other Tribal Areas listed in the table rows, use the Previous Zoom and Next
Zoom buttons. The previous or next row highlights and the system zooms to the map for
that row.

Step 6

You may use the Search feature at the bottom of the dialog box to filter the table layers by
specific attributes (e.g., full name, MTFCC, change type, etc.).

Step 7

First, select the layer you want to view (in this example, we will select the AIAL (Tribal
Area) layer).

For each feature changed for a Tribal area, the attributes of the changed feature display in
the table rows. Each column gives the name of the attribute.

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 108

Step
Step 8

Action and Result
In the Column Name drop-down menu, select the attribute by which you want to filter.

In this example, we will select change type (CHNG_TYPE).
Step 9

Finally, in the Select drop-down, select the attribute value by which you want to filter, then
click the Search button. In this example, we will select ‘Boundary Correction’.

After you click Search, the attribute table is filtered to show the rows for all boundary
corrections made in the AIAL (Tribal Area) layer.

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 109

Step

Action and Result
To view an individual boundary correction, click on its row and click the Zoom button. To
return to the attribute table to see the full (unfiltered) county subdivision layer, click the
Refresh button

in the upper right-hand corner of the dialog box.

Note that when filtering the table by some attributes (e.g., state and county FIPS code or
MTFCC), no drop-down list appears from which to make a selection. This is because some
attribute codes are too numerous to make scrolling through a list practicable. Instead you
will receive a blank box in which you may type the search value. For example, if you are
filtering the area landmarks layer by MTFCC and want to see hospitals in the layer, type in
the MTFCC for hospitals (K1231), as shown below, then click Search.

6.5.2

Review Change Polygons Tool

The Review Change Polygons tool allows you to view the transactions created from the edits
you made to legal entities, as well as to area landmarks and hydrographic areas. You can
review the transaction polygons that represent boundary changes, as well as new
incorporations and disincorporations. The tool also allows you to make corrections to change
polygons.
Notes on Reviewing Change Polygons
You must run the Review Change Polygons tool before GUPS will export a file.
You must run the Review Change Polygons tool for each county in which you worked. For
example, if you made changes to your working county, but also made changes to an adjacent county
when annexing land for your county, you must run the change polygon check on both counties.

To use the Review Change Polygons tool, follow the steps in Table 41.

Step
Step 1

Action and Result
In the Map Management dialog box, make sure the Tribal Area for which you want to run
the check appears in the Entity field.

Once you click the Open button at the bottom of the dialog box and the map opens in
Map View, you are ready to run the Review Change Polygons check.

Step
Step 2

Action and Result
Once you have loaded the entity, you are ready to begin the change polygons review.
Click on the Review Change Polygons button on the BAS toolbar.

The Review Change Polygons dialog box opens just below the Table of Contents.

Note: This box can be dragged anywhere on your screen and docked.
Step 3

Use the Geography drop-down menu shown below to select the geography you want to
review.

Step 4

After you select an entity type, the Small Area Check and Find Holes buttons become
active and all change polygons for the entity type you selected appear in the Info list at
the bottom of the box.

Step 5

To check for small area change polygons, click the Small Area Check button. If all your
change polygons are of sufficient size, a pop-up box informs you of this.

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Step

Action and Result

Step 6

If you have small area polygons within the Reservation/Trust Land, they appear in the
Info list with their acreage noted in the Area in Acres column. The Display All Changes
button also becomes active (this button allows you to toggle back to see all change
polygons in the list).

Step 7

To view a polygon on the map, click the row for the polygon in the Info list. The polygon is
highlighted and the map zooms to the location of the polygon.

Note in the illustration above, we moved the Review Change Polygons box to sit over
the map. As stated earlier, you may move the box anywhere on the page and dock it.
Step 8

To delete polygons that are too small (less than 500 square feet), click on the row for the
change polygon in the Info list. The Delete Change Polygon button appears.

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 112

Step

Action and Result

Step 9

To delete the polygon, click the Delete Change Polygon button. A pop-up box asks if
you are sure you want to delete.

Step 10

Click the Yes button. The polygon is removed from the list, from the map, and from the
attribute table.

Step 11

Before the Small Area check is complete, you must repeat the steps above for each
geography type for which you created change polygons.

Step 12

Next, review your polygons for holes (that is, two or fewer small faces missed when
creating a change polygon). While still in the Review Change Polygons dialog box,
select a geography type from the Geography drop-down menu. For this example, we
again selected ‘Reservation/Trust Lands’. A list of change polygons for
Reservations/Trust Lands populates the Info list and the Display All Changes button
replaces the Small Area button (since you’ve already run this check). The Find Holes
buttons remains in its original location.

Step 13

Click on the row for the polygon in the Info list to see it on the map, then click the Find
Holes button. If no holes are present, a pop-up box informs you of this.

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 113

Step

Action and Result

Step 14

If holes are found, a list of polygons with holes appears in the Holes Review box and the
Fix button activates at the bottom of the box.

Step 15

To correct a change polygon, click on its row to highlight it. The map zooms to its location
and displays all holes in cyan (color may vary).

Step 16

Click the Fix button to repair the hole. The change polygon is corrected and the correction
displays on the map (i.e., the hole is changed to the same color as the remainder of the
polygon).

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page 114

Step

Action and Result

Step 17

Before the Find Holes check is complete, you must repeat the steps above for each
geography type for which you created change polygons.

Step 18

After you review for small areas and holes, you may also use the Review Change
Polygons tool to check the general accuracy of your change polygons. To do so, select
your entity type in the Geography drop-down menu. A full list of change polygons for the
geography type selected displays in the Info list.

Step 19

Step 20

To review a boundary change, click on the change polygon in the list, then click the Legal
Entity Change button at the bottom of the Review Change Polygons dialog box, shown
below.

The map zooms to where the change was made and a box opens displaying the
information that you entered when you coded the change. Here, because the change was

Step

Action and Result
a boundary correction, the effective date, authority type, and documentation fields are not
filled.

If this change was mistakenly coded as a boundary correction, and should have been a
legal change instead, you may correct the error here. In this example we correct a change
polygon mistakenly coded as a boundary correction rather than an addition.
Step 21

Click the calendar icon next to the EFF_DATE field to select an effective date for the
addition.

Step 22

Use the drop-down menu for the AUTHTYPE field to select the authority type for the
change.

Step 23

In the DOCU field, type in the ordinance or other legal documentation number authorizing
the Addition, or upload legal documentation for the change. To upload documentation,
click the folder icon next to the DOCU field.

Then, to upload it, click the Open button at the bottom of the DOCU window.

GUPS uploads the file and the file name appears in the DOCU field.
Step 24

Step 25
Step 26

Finally, in the CHNG_TYPE field drop-down menu, change ‘Boundary Correction’ to the
correct change type (‘Annexation’, ‘Corridor’, or ‘Offset’). Here we select ‘Annexation’.

Click the OK button.

The correction is made.

When you have completed all your reviews (for small areas, holes, and boundary
changes) for all entity types, and have made any corrections needed, click the Save
button
on the BAS toolbar. All corrections are saved. Your Review Change
Polygons check is complete.

APPENDIX B. GEOGRAPHIC OFFSETS
Geographic Offsets
A geographic offset is an area (either within or outside of a geographic entity) that is only on one
side of a road (unlike corridors, which involve both sides of the road) and does not include
structures addressed to that side of the road. Much of the same guidelines regarding corridors
also holds true for offsets.
The Census Bureau is aware that many governments base their legal boundaries on cadastral
(parcel-based) right-of-way mapping. Census Bureau maps are based on spatial data that is
topologically integrated which makes maintenance of geographic offsets inefficient. Using the
road centerline wherever possible will help to establish more accurate population counts. If a
boundary follows a front lot line, the Census Bureau strongly prefers that the road centerline be
used as the boundary. If a boundary is at the rear of a lot, then it should be depicted as such. If
it is unclear whether a particular line is a front lot line or something else, please contact the BAS
team for assistance. As a rule, if a house or building could not conceivably be built in the area
between the potential line and the centerline of the road, then the line can be considered a front
lot line Figure 13. A Cadastral (Parcel-Based) Boundary Map depicts a cadastral (parcelbased) boundary map and Figure 14. How a Boundary Should be Represented When Sent
to the Census Bureau shows how the boundary should be represented when it is sent to the
Census Bureau.

Figure 13. A Cadastral (Parcel-Based) Boundary Map

Figure 14. How a Boundary Should be Represented When Sent to the Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

Page B-1

Figure 15. Place Boundary – Front Lot Line

Figure 15 - Shows a situation in which the place boundary is along the front lot line. In this
example, the respondent must either use the road centerline as the boundary (preferred), or
create an offset.

Figure 16. Place Boundary – Rear Lot Line

Figure 16 - The place boundary is on the rear lot line, so the respondent should of course not use
the road centerline or create an offset, but should rather digitize in a new boundary following the
rear lot line.
The Census Bureau has included an “offset” shapefile in the BAS materials
(bas_2018_offset_.shp), so that your jurisdiction can be checked for any existing
corridors or offsets. While the Census Bureau prefers that new offsets are not created (see
above), this information can be helpful in determining if current boundaries are correct..

or more lanes of traffic in each direction, may or may not be
divided, and usually have at-grade intersections with many other
roads and driveways. They often have both a local name and a
route number.
Generally a paved non-arterial street, road, or byway that usually

PAPERWORK REDUCTION ACT STATEMENT
A federal agency may not conduct or sponsor, nor shall a person be subject to a penalty for failure to
comply with a collection of information subject to the requirements of the Paperwork Reduction Act
(PRA) unless that collection of information displays a current valid Office of Management and Budget
(OMB) Control Number. This collection is voluntary. The authority for conducting this collection comes
from Title 13 Unites States Code (U.S.C.), Section 6.
The OMB Control Number for this information collection is 0607-0151. Public reporting for this
collection of information is estimated to be approximately 2 hours per response, including the time for
reviewing instructions, completing and reviewing the collection of information.
Comments concerning the accuracy of this burden and suggestions for reducing the burden should be
directed to:

INTRODUCTION
A.

The Boundary and Annexation Survey

The U.S. Census Bureau (Census Bureau) conducts an annual survey called the Boundary and
Annexation Survey (BAS) to collect information about selected legally defined geographic areas,
such as counties (and equivalent areas), incorporated places, minor civil divisions (MCDs),
federally recognized American Indian Areas (AIAs), including reservations, off-reservation trust
lands and tribal subdivisions, Hawaiian Homelands, and Alaska Native Regional Corporations
(ANRC). BAS also provides an opportunity for participants to review the names and geographic
relationships for these areas. Title 13, U.S.C., Section 6, authorizes this survey.
The Census Bureau uses the boundary information collected during the BAS to tabulate data for the
decennial and economic censuses, and to support the the American Community Survey (ACS).
Maintaining correct boundaries and boundary-to-feature relationships through the BAS helps ensure
that the Census Bureau assigns the appropriate population to each governmental unit (GU).
In compliance with the Office of Management and Budget Circular A-16, the BAS supports the Census
Bureau’s spatial data steward responsibilities for the Federal Geographic Data Committee (FGDC) and
the Geospatial One-Stop by updating the inventory and boundaries of GUs.
In addition, the BAS is the source of up-to-date information on changes to the boundaries, codes and
names of incorporated places, MCDs, counties (and equivalent areas), Hawaiian Homelands, ANRC, and
federally recognized AIAs, which include reservations and off-reservation trust lands used by the U.S.
Geological Survey’s (USGS), the National Map, and the Geographic Names Information System (GNIS).
Please visit the BAS program Web site at . For
more information on the BAS, please view the “Introduction to BAS” video series on the Census Bureau’s
BAS Web site at .

What’s New for the 2018 BAS?
1. The Geographic Partnership Support Desk (GPSD) is now fully functional and available to assist

with any questions respondents may have regarding BAS.
2. Redistricting data contacts participating in the Voting District Project (VTD) may submit

boundary updates for reconciliation with BAS contacts.

Key Dates for BAS Respondents

January 1, 2018 — All boundary changes must be legally in effect on or before this date to be
reported in the 2018 BAS.
March 1, 2018 — BAS submission date deadline for boundary updates to be reflected in the ACS and
PEP published data. Boundary submissions received by this date are also reflected in next year’s BAS
materials.

Boundary and Annexation Survey Tribal Respondent Guide: Digital

Page viii

May 31, 2018 — BAS boundary updates submitted by this date will be reflected in next year’s BAS
materials.

BAS State Agreements

The Census Bureau has established a number of arrangements with states for reporting boundary
changes. Please visit the BAS State Agreements webpage within the BAS program Web site at
or call (800) 9725651 for information regarding state agreements.
Note: The Census Bureau can only establish BAS state agreements for states that require local governments to
report boundary changes to a state agency.

Legal Disputes

If the Census Bureau discovers that an area of land is in dispute between two or more jurisdictions, the
Census Bureau will not make any boundary corrections until the parties come to a written agreement, or
there is a documented final court decision regarding the dispute. If you have questions concerning this,
please contact the Census Bureau Legal Office at 301-763-9844.
For disputes involving tribal areas, the Census Bureau must defer to the Office of the Solicitor at the
Department of the Interior for a legal opinion. Often complicated land issues require an extended period
of time for resolution, and in those cases, the Census Bureau will retain the current boundary in the
database until a legal opinion is issued by the Solicitor’s office.

PART 1: DIGITAL BAS REQUIREMENTS
1.1

Digital BAS Participation Requirements

All participants must have the ability to edit a Census Bureau shapefile. The Census Bureau requires that
entities update Census Bureau shapefiles with boundary and feature changes, rather than submitting a
shapefile from a local Geographic Information System (GIS);

All participants must provide current contact information for the tribal BAS point of contact, the person
updating the shapefiles, and the tribal chair;

All participants must provide legal documentation (such as trust deeds and Federal Register Notice) and
effective dates for all legal boundary changes (new reservation land and/or off-reservation trust lands);

Each non-legal boundary correction must contain proper update documentation; and

All participants must use the SWIM to submit their changes to the Census Bureau. Due to security
requirements, we cannot accept submissions via FTP, email or any protocol other than the SWIM site
(). If you indicated on your Annual Response Form that you wished

Tribal Areas that can be Submitted through BAS

The following can be updated through Tribal BAS:

•

Federal American Indian Reservations are areas that have been set aside by the United States for the use
of tribes, the exterior boundaries of which are more particularly defined in the final tribal treaties,
agreements, executive orders, federal statutes, secretarial orders, or judicial determinations.

Trust lands may be located on or off a reservation; however, the Census Bureau tabulates data only for
off-reservation trust lands. Please do not submit on-reservation trust land because the Census Bureau
can only show the exterior reservation boundary.

•

Federal Off-Reservation Trust Lands are areas for which the United States holds title in trust for the
benefit of a tribe (tribal trust land) or for an individual American Indian (individual trust land).

The Census Bureau does not identify fee land (or land in fee simple status) or restricted fee lands as
specific geographic areas.

•

Tribal Subdivisions are legal administrative subdivisions of federally recognized American Indian
reservations and off-reservation trust lands and are described as additions, administrative areas, areas,
chapters, county districts, communities, districts, or segments. These entities are internal units of selfgovernment or administration that serve social, cultural, and/or economic purposes for the American
Indians on the reservations and off-reservation trust lands.

•

Hawaiian Homelands are areas held in trust for Native Hawaiians by the state of Hawaii, pursuant to the
Hawaiian Homes Commission Act of 1920, as amended.

Alaska Native Regional Corporation (ANRCs) were created pursuant to the Alaska Native Claims
Settlement Act (ANCSA) enacted in 1971 as a "Regional Corporation" and organized under the laws of the
state of Alaska to conduct both the for-profit and non-profit affairs of Alaska Natives within a defined
region of Alaska.

BAS Informational and Tutorial Videos

The Census Bureau created training videos to give BAS participants detailed instructions and information
on how to report and submit BAS changes. These videos are available on the BAS Web site at:

PART 2: TOPOLOGICAL RELATIONSHIPS AND SPATIAL
ACCURACY
The Geography Division of the Census Bureau is responsible for developing geographic applications and
executing related activities needed to support the Census Bureau in collecting and disseminating census
data. For more than twenty years, the Census Bureau’s Master Address File/Topologically Integrated
Geographic Encoding and Referencing (MAF/TIGER) System has become critical resources for supporting
the Census Bureau in its geographic activities.
The following section will describe how the Census Bureau uses a topologically integrated system and
how this differs from traditional GIS systems, which use separate layers of data.

2.1.

Topological Relationships in MAF/TIGER

At the Census Bureau, we describe topology as the relationship between different levels of geography.
MAF/TIGER is a geographic database in which the topological structures define the location, connection,
and relationships of streets, rivers, railroads, and other features. These topological structures help
define the geographic entities for which the Census Bureau tabulates data.
Instead of having a separate layer for each feature class (roads, boundaries, etc.) all MAF/TIGER
information is stored in one layer or file. See Figure 1 and Figure 2 for samples of topologically
integrated files in MAF/TIGER.

Figure 1. Road Representing 3 Types of Boundaries

Boundary and Annexation Survey Tribal Respondent Guide: Digital

Page 4

This example shows how a road in MAF/TIGER can also represent a block
boundary, American Indian Areas (AIAs) boundary and a school district
boundary.

Figure 2. Typological Integration of Four Classes

This example shows how four different feature classes are topologically
integrated into one layer. One road feature represents not only a road, but also
a block boundary, AIA boundary, and a school district boundary.

2.2.

GIS and Spatial Accuracy

In a GIS, feature classes are usually not topologically integrated: they are separated into layers. When
you overlay these layers in a GIS, there may be boundary misalignments due to the nature of the data.
These non-topologically integrated layers could cause issues in MAF/TIGER. Figure 3 and Figure 4 show
how files that are not topologically integrated might appear in a GIS when overlaid.
Boundary and Annexation Survey Tribal Respondent Guide: Digital

Page 5

Figure 3. Overlay of Four Feature Classes

This example shows an overlay of four different feature classes. Notice how the
topological relationship is compromised. The block, AIA, and school district
boundaries, which are supposed to follow the road feature, no longer align
with the road in several locations.

Figure 4. GIS Place Boundary Does Not Follow Road Feature

This example shows a situation where a local GIS AIA boundary does not follow
a road feature. Assuming that the boundary follows the road feature, changing
the AIA boundary to match the local file exactly, and become misaligned (see
arrows) would dissolve the topological relationship in MAF/TIGER.
The spatial differences between local GIS data and the Census Bureau’s topologically integrated file are
often very small (less than ten feet) and can create boundary-to-feature relationship issues for the
Census Bureau. Part 5: Updating the Census Bureau Shapefiles, Section 5.6 provides instructions on
how to review digital submissions for small spatial boundary corrections. It also lists some of the
potential consequences of making spatial boundary corrections that dissolve the topological
relationships present in MAF/TIGER. You may find examples of suggested methods for correctly making
boundary changes in
Appendix B and Appendix C.

PART 3: CENSUS BUREAU PROVIDED SHAPEFILES
Please download shapefiles from the Web site in order to review your boundaries and submit changes.
Please review and edit all applicable shapefiles. For example, if your tribe has new off-reservation trust
land to report, you would use the “aial” shapefile. If your tribe also had tribal subdivision updates, you
would use the “aial” shapefile and the “aitsl” shapefile. See Table 1 for the names of the shapefiles. The
Census Bureau provides entity layers in ESRI shapefile format for download via the Web site.
Note: Shapefiles are ‘county’ based so you will need to download all the counties in which the tribe has
reservation and/or ORLTs.

PART 4: CENSUS BUREAU GEOCODING
Geocoding is how the Census Bureau codes population to geographic entities. There are two primary
methods of geocoding used by the Census Bureau. Both of these involve coding an address to a spatial
polygon, but one uses Global Positioning System (GPS) technology, while the other uses address ranges.

4.1

MAF Structure Point Geocoding

A field worker stands in front of a house or living quarters, and records the physical location with a GPS
device (Figure 5). Usually, the GPS point should fall very close to the front door of the house. However,
since this is a field operation, real-world obstacles like locked fences, poor satellite reception, or even
aggressive dogs might sometimes prevent the worker from gaining access to the front door. In these
circumstances, the worker may have to take the GPS coordinate from the sidewalk or side of the road.

Figure 5. MSP Method of Geocoding

MAF Structure Point (MSP) method of geocoding. Notice that it is occasionally
not possible for the field worker to go all the way to the front door, due to
unforeseen circumstances, like the fence or the dog shown above. Thus, the
MSP (represented here by the red pins) can sometimes fall within the road or
the road right-of-way.

Boundary and Annexation Survey Tribal Respondent Guide: Digital

Page 10

4.2

Address Range Geocoding

When no MSP Geocoding is available, the Census Bureau codes houses and living
quarters according to a potential range of addresses associated with the adjacent stretch
of road (Figure 6).

Figure 6. Address Range Method of Geocoding

When it is not possible to collect an MSP, houses are geocoded according to
their placement along a range of potential addresses along that road. Since the
address is being related to the road, boundaries placed on front lot lines will
lead to mis-geocoding unless an offset flag is used.
While the two methods of geocoding differ greatly, both rely heavily on the integrated nature of
MAF/TIGER. These geocoding methods are affected by the way streets and boundaries are represented
in relation to one another. This interdependence between streets, boundaries, and geocoding means
that Census Bureau representations of legal boundaries may sometimes differ from other
representations (e.g., in local or state GIS). This is especially true regarding geographic corridors and
offsets that follow road right of ways (or the front lot lines of parcels). In both of the examples above,
delineating a boundary along the front lot line will tend to increase the risk of incorrect geocoding. As a
result, using the road centerline as a boundary is the safer method.

PART 5: UPDATING THE CENSUS BUREAU SHAPEFILES
Census Bureau shapefiles can be updated to reflect boundary and/or linear feature changes that have
occurred since the last Tribal BAS survey. Examples of these procedures can be found in Appendices B
and C and in the Digital BAS demonstration video series at
Note: If there are problems with the processing of returned files, the Census Bureau will email a feedback
document requesting clarification of any issues. If the problem cannot be resolved before the project
deadline, the changes in question will not be made during the current BAS.

5.1

General File Setup Guidelines

After downloading the shapefiles from the PVS download page, follow these procedures before
beginning actual updates:

•
•
•

5.2

Open the downloaded .ZIP file to verify its contents.
Copy the shapefiles into a directory on a server/hard drive.
Open the shapefiles with GIS software.

Changing the Map Projection

Census Bureau files are in GCS NAD83 format and can be projected into any local coordinate
system/projection. Most GIS software packages will allow users to transform file coordinate systems and
projections. For example, if using ArcView to update files, activate and utilize ArcView’s Projection
Utility Wizard extension. If using ArcGIS, use its Project tool in ArcToolbox. MAF/TIGER shapefile
extracts contain defined projection information in the *.prj file. ArcView and ArcGIS access the *.prj file
for projection information so there is no need to define these parameters before changing the file
coordinate systems.
When updates are complete, participants may submit the boundary shapefile using any local coordinate
system/projection if the shapefile contains a .prj file or spatial reference materials such as metadata.

5.3

Boundary Changes

In order to update MAF/TIGER, participants must create a separate change polygon layer for each
updated entity type (AIA, ANRC, tribal subdivision, or Hawaiian Homeland). Please create change
polygons in relation to the current MAF/TIGER boundary.
Appendix B and Appendix C provide two examples for creating annexation, deannexation, boundary
correction, new incorporation, geographic corridor, and geographic offset change polygons. Review any
boundary change polygons before submitting them (Section 5.7).
If you need additional shapefiles, please contact the Census Bureau at 1-800-972-5651 or
[email protected].

5.3.1

Additions and Deletions

The Census Bureau will accept additions and deletions from AIAs, ANRCs, and Hawaiian Homelands,
such as new reservation lands and off-reservation trust lands. Each addition or deletion change polygon
must have the required attributes and corresponding change type populated, as seen in Table 2. The
Census Bureau will snap any addition or deletion to a MAF/TIGER feature when it exists within thirty
feet of that feature.
Note: Enter the name of the jurisdiction (AIA, ANRC or Hawaiian Homeland) adding or deleting the area in the
NAME field.

Boundary Corrections

The Census Bureau will also accept specific boundary corrections from AIAs, ANRCs, and Hawaiian
Homelands. As with new reservation lands and off-reservation trust lands, the participant must create
individual change polygons for each boundary correction. Each boundary correction must also have the
required attributes and corresponding change type populated, as seen in Table 3, or the Census Bureau
will reject them.
Note: Enter the name of the jurisdiction that the boundary correction is for in the NAME field.

Boundary and Annexation Survey Tribal Respondent Guide: Digital

Page 15

boundary corrections that the Census Bureau will accept, process, and update or reject during the
current BAS.
The Census Bureau will accept and process properly documented boundary corrections during the
current BAS that spatially interact with (abut) other BAS legal changes (annexation, deannexation,
corridor, offset) and meet both of the following two conditions:

•

In situations where the existing boundary has been digitized incorrectly or appears in the incorrect
location due to Census Bureau activities; and

•

Where the overall shape of the geographic entity is maintained and no feature-to-boundary relationships
are dissolved.

The Census Bureau will reject boundary corrections:

•

That dissolve boundary-to-feature relationships (roads, rivers, railroads, etc.) if the difference is less than
thirty feet;

•

Which are greater than one square mile, or not contiguous with the rest of the entity boundary. These
boundary corrections may be part of additions which were never reported to the Census Bureau. If so,
legal documentation should be provided; and

•

That have a width of less than thirty feet over the entire polygon.

Note: Remember that the Census Bureau will snap any entity boundary correction to a MAF/TIGER feature when
it exists within thirty feet of that feature.

5.3.3

New Tribal Subdivisions

AIA participants may submit new entities (tribal subdivisions) through Tribal Digital BAS. As with other
change types, an individual change polygon must be created for each new entity and possess the
required attributes and the corresponding change type field must be populated (see Table 4). Please see
Section 5.4 for more information about tribal subdivisions.
Note: Enter the name of the new jurisdiction in the NAME field.

5.3.4

Geographic Corridors

The Census Bureau geocodes addresses based on the street centerline. If the geocoding of these
addresses would result in the assignment of population to the incorrect geographic entity, participants
should create a geographic corridor.
A geographic corridor is an area that includes only the road right-of-way and does not contain any
structures addressed to either side of the street. Figure 7 shows a corridor created where the AIA owns
the right-of-way but the housing units are not included within the AIA (shown in color). Without a
corridor, the housing units along this road would be included in the AIA.
Figure 8 shows that the right-of-way belongs in the unincorporated area, while the housing units are
included in the AIA (shown in color). This is important for some entities because they are portraying that
the entity is not responsible for road maintenance. This is not relevant for Census Bureau tabulations
and is not easy to depict in the Census Bureau’s nationwide database. This type of corridor should not
be included in a BAS response.

Figure 7. Geographic Corridor Created
Figure 8. Geographic Corridor Not Created

The image on the left (Figure 7) shows that a geographic corridor should be
created to allow for proper geocoding of homes. The image on the right (Figure
8) shows that the geographic corridor should not be created and features
should be snapped to the street centerline.
The Census Bureau will accept new geographic corridors. Please create individual change polygons for
each new geographic corridor. Each change polygon must have the required attributes and
corresponding change type populated, as seen in Table 5. In the NAME field, enter the name of the
jurisdiction. In the RELATE field, indicate whether the change is adding IN or taking OUT (removing) the
corridor.

5.3.5

Geographic Offsets

A geographic offset is an area claimed by a geographic entity that is only on one side of a road and does
not include structures addressed to that side of the road.
The Census Bureau is aware that many governments base their legal boundaries on cadastral (parcelbased) right-of-way mapping. The Census Bureau bases their maps on spatial data that is topologically
integrated. This makes the maintenance of geographic offsets inefficient. Snapping an entity boundary
to the centerline wherever applicable will help to establish more accurate population counts. If a
boundary is the front lot line, Census Bureau strongly prefers
that the boundary be snapped to the road. If a boundary is at the rear of a lot, then please depict it as
such. Figure 9 depicts a cadastral (parcel-based) boundary map and Figure 10 shows how the boundary
should be reported when sent to the Census Bureau.

Figure 9. Cadastral Data
Figure 10. Same Data Edited to Census Requirements

On the left in Figure 9 is an example of cadastral data. Figure 10 on the right, is
the same area shown edited to conform to census requirements.
The Census Bureau will accept new geographic offsets. Please create individual change polygons for
each new geographic offset. Each change polygon must have the required attributes and corresponding
change type populated, as seen in Table 6. In the NAME field, enter the name of the jurisdiction. In the
RELATE field, indicate whether the change is adding IN or taking OUT (removing) the area represented
as an offset.

Census Bureau has included an “offset” shapefile in the BAS materials (PVS_18_v2_offset_.shp),
so that your jurisdiction can be checked for any existing corridors or offsets. While the Census Bureau
prefers that you do not create new offsets, (see above), this information can be helpful in determining if
current boundaries are correct.

5.4

Tribal Subdivisions

Tribes may submit the boundaries for one type of administrative area within their reservation(s) and/or
off-reservation trust lands (land base) for inclusion in MAF/TIGER. The Census Bureau will consider any
type of unit of self-government or administration as a “tribal subdivision.” Tribal subdivisions should
cover all, or most, of the tribe’s land base. If a tribe has more than one type of distinct administrative
area that could qualify as a tribal subdivision (such as tribal election districts, tribal water districts, or
health service areas with different boundaries), the tribe may submit only one type of subdivision. Tribal
subdivisions can be considered either active (A) or inactive (I). Active subdivisions are defined as having
a functioning government with elected officials that provide programs and services. Inactive subdivisions
have no functioning government or elected officials and receive services solely from the tribe. Some
examples of areas submitted as tribal subdivisions are:

•

Areas used by a tribe for the election of tribal government officials (such as districts or precincts used for
the election of tribal council members).

•
•

Areas used by a tribal government for tax purposes.

•
•

5.4.1

Areas used by a tribal government for the provision of general services or specified services, such as:
o

Water districts;

Health service areas;

Emergency service delivery areas (such as 911, fire, and/or police); or

Grazing districts or range units.

Historical or traditional areas recognized by a tribal government.
Local tribal community governments.

Criteria for Defining Tribal Subdivisions

•

The delineation of tribal subdivisions is restricted to the area contained within reservation(s) and/or
associated off-reservation trust lands (land base).

•
•
•
•

There is no minimum population threshold for a tribal subdivision.
Tribal subdivisions should cover all, or most, of the tribe’s land base.
A tribal subdivision may be discontinuous.
A tribe may designate only ONE type of tribal subdivision. If a tribe has more than one level of tribal
subdivisions within its land base, the Census Bureau recommends delineating subdivisions corresponding

Boundary and Annexation Survey Tribal Respondent Guide: Digital

Page 19

to the lowest geographic level (those geographic areas containing the smallest area) of the tribe’s
administrative hierarchy.

•

Tribal subdivisions should not be based solely on land ownership or other cadastral areas, nor should they
consist of divisions based on the U.S. Public Land Survey System (PLSS) of townships, ranges, and sections,
if these areas have no governmental or administrative function for your tribe.

•

Some examples of descriptors for tribal subdivisions are:

5.4.2

District;

Community;

Area;

Chapter;

Segment;

Administrative Area;

Addition; and

County District.

Updating Tribal Subdivisions

Tribal Subdivisions are updated in a similar manner to boundary changes (such as additions or
deletions). In order to submit tribal subdivision updates, please create a separate tribal subdivision
change polygon layer. Updates that can be made to tribal subdivisions include additions, deletions,
boundary corrections (adding and removing area), and creating new tribal subdivisions. Please note that
all tribal subdivision updates (additions, deletions, name changes, and new entities), with the exception
of boundary corrections, require a tribal resolution. Table 7, Table 8, and Table 9 displays the required
attributes for each of the change types. Review the example processes in Appendix B and Appendix C
for information on how to create change polygons. Change polygons for tribal subdivisions may be
created in the same manner as for reservations and off-reservation trust lands.

5.5

Linear Feature Updates

5.5.1

Adding, Deleting, Renaming, and Recoding Linear Features

The Census Bureau will accept linear feature modifications when needed. Please submit linear feature
updates in a separate linear feature update layer. Each linear feature update must have the required
attributes and corresponding change type populated, as seen in Table 7. In the TLID field, preserve the
existing TLID for the feature.

provide the name and MTFCC.

•
•

If a feature does not exist and is in the Census Bureau’s feature network, delete the feature.

5.5.3

If a feature is in the incorrect location in the Census Bureau’s feature network, delete the feature and readd it in the correct location. Only do this if the feature is very far off or in the wrong position relative to
boundaries or other features.

Address Range Updates

The Census Bureau accepts address range data as part of the linear feature update layer. As with other
linear feature updates, address ranges must have the required attributes and corresponding change
type populated. As existing address ranges cannot be shown in our outgoing shapefiles, we recommend
that participants generally only add address ranges to new features.

The Census Bureau also cannot delete or modify any point landmarks imported from the USGS GNIS
database. Changes submitted for the following types of landmarks may be left unchanged:

•
•
•
•
•

K2451 (Airport);
K2582 (Cemetery);
C3022 (Summit or Pillar);
C3081 (Locale or Populated Place); and
C3061 (Cul-de-sacs).

Due to heavy workloads for boundary changes to legal areas, changes to point landmarks may not be
added to the database until after the next year’s BAS materials are created. It may take two BAS cycles
in order to see these changes reflected in local materials.

5.7

Reviewing Changes to the Census Bureau Shapefiles

Please review all changes to ensure that they are intentional and correct. The Census Bureau has
created videos with information on many of the topics below. The video series, “Introduction to the
Digital BAS” can be found on the web at: .

5.7.1

Boundary-to-Feature Relationships

Please review all changes to ensure that the correct boundary-to-feature relationships are being created
or maintained. The Census Bureau is aware that many governments base their legal boundaries on
cadastral (parcel-based) right-of-way mapping; however, the Census Bureau bases maps on spatial data
that is topologically integrated. Therefore, snap boundaries to street centerlines (or rivers, railroads,
etc.) wherever applicable. This will help establish a more accurate population count for tribal entities.
The following examples show situations where boundary changes should be snapped to existing linear
features. The Census Bureau will snap boundary changes to any linear feature within thirty feet.

Boundary and Annexation Survey Tribal Respondent Guide: Digital

Page 27

Figure 12. Boundary Correction Not Snapped to Existion Linear Features

These boundary corrections are not snapped to existing linear features in
MAF/TIGER. Both boundary corrections should be snapped to centerlines or
population may be assigned to incorrect entities.

Boundary and Annexation Survey Tribal Respondent Guide: Digital

Page 28

Figure 13. Annexation Created without Snapping to Centerlines

This is an example of an addition that has been created without snapping to
existing centerlines in MAF/TIGER. Unless the boundary is snapped to
centerlines, some of the population may be assigned to an incorrect entity.
The Census Bureau will not accept boundary corrections that dissolve the current relationship between
an existing boundary and linear feature. Any boundary corrections that create thirty feet or less of gap
or overlap between the existing linear feature and boundary will not be incorporated into MAF/TIGER.
See below for examples of changes that will not be accepted.

Figure 14. Small Saptial Correction Not Incorported

Small spatial boundary corrections would dissolve the relationship with the
river. These boundary corrections will not be incorporated into MAF/TIGER.

Boundary and Annexation Survey Tribal Respondent Guide: Digital

Page 29

Figure 15. Small Spatial Corretion Not Acepted

Small spatial boundary corrections that dissolve the boundary-to-feature
relationship with multiple streets have been created. Incorporating these
changes would affect the population counts for the area. Therefore, the Census
Bureau will not accept these small boundary corrections.

5.7.2

Large Boundary Corrections

The Census Bureau will not accept large boundary corrections to an AIA without the appropriate legal
documentation (such as Trust Deed, Executive Order, new legal opinion, Act of Congress, or Federal
Register Notice). These large boundary corrections may be legal boundary changes that occurred in the
past and were never reported to the Census Bureau. Please submit the appropriate legal documentation
and effective date so that changes may be incorporated into MAF/TIGER.

Boundary and Annexation Survey Tribal Respondent Guide: Digital

Page 30

Figure 16. Large Boundary Corrections

Without the appropriate documentation, Census Bureau will not accept large
boundary corrections.

Note: There may be a few instances when large boundary corrections need to be made because of incorrect
digitizing or where the boundary appears in the incorrect location due to other Census Bureau activities.

5.7.1

Including Required Attribute Information

It is important to review each change polygon and confirm that the correct attribute information is
included. Without the correct attribute information, the Census Bureau will be unable to process and
incorporate the changes into MAF/TIGER. See Section 5.3 for the required attribute information and
corresponding change type codes.

5.7.2

Including Appropriate Metadata (Projection Information)

It is important that the appropriate projection information is included. Each update layer submitted
should contain a *.prj file so that the Census Bureau can convert the projection back to GCS_NAD83. If
the GIS being used cannot create a *.prj file, include the projection information in metadata. This is
critical for the Census Bureau to be able to process the file and incorporate the updates into
MAF/TIGER.

5.7.3

Linear Feature Update

Please review linear feature changes to ensure that they align with the features currently in MAF/TIGER.
If linear feature changes do not align with current MAF/TIGER linear features, the Census Bureau may
not incorporate the submitted updates.

image on the right (Figure 19) shows the correction; connecting the new roads
to the existing road features.

Boundary and Annexation Survey Tribal Respondent Guide: Digital

Page 32

5.8

Additional Review Information

The Census Bureau will not make any boundary change that affects adjacent legal entities without the
appropriate documentation. Review any change polygons that affect adjacent entities to determine if
they are intentional, legal changes.
Note: The Census Bureau will snap any addition, deletion, or boundary correction to a MAF/TIGER feature when it
exists within thirty feet of that feature. This helps maintain the boundary-to-feature relationships in
MAF/TIGER and will ensure correct housing tabulation counts for entities.

5.8.1

Submitting Acceptable Documentation

The Census Bureau is responsible for depicting reservation and off-reservation trust land boundaries but
because the Census Bureau is not the authority on the boundaries, we require documentation to update
reservation and off-reservation trust land boundaries.
The following changes require documentation:

•
•
•

New off-reservation trust land;

•
•
•

Large changes to existing off-reservation trust land;

New reservation land;
Changes from off-reservation trust land to reservation land and changes from reservation land to offreservation trust land;
Large changes to existing reservation land; and
Boundary corrections to off-reservation trust land or reservation land that do not follow the general
shape of the boundary.

For off-reservation trust land, the most common documentation is a trust deed or a letter from the BIA.
Documents should state that the land is “in trust” for your tribe.
For reservation land, documentation examples include (but are not limited to) federal register notice,
Act of Congress, Executive Order, or a new legal opinion issued by the BIA. When submitting large
boundary corrections to an existing reservation, please submit your reservation document.
If you cannot locate your documentation, you can contact your regional BIA office to obtain
documentation. The Census Bureau will treat legal opinions issued in writing from the BIA as
documentation since the BIA is the authority on reservation and off-reservation trust land boundaries. If
the Census Bureau cannot interpret a document, such as a treaty, the Census Bureau will contact the
BIA for assistance.
If you have questions about documentation, please call the Census Bureau at
1-800-972-5651 or email [email protected]. If you need to contact the BIA, please see
for contact information for your regional
office.

Submitting Digital Data

5.8.2

If a participant is reporting changes to the BAS, the Census Bureau requires that each participant submit
at least one shapefile (change polygons). The total number of layers submitted depends on what types
of changes are reported. The following is a list of change layers that may need to be submitted:
1.

Change Polygon Layers (ANRC, AIA, Tribal Subdivisions, Hawaiian Homelands)
•
•

Whole Modified Entity Layer (ANRC, AIA, Tribal Subdivisions, and Hawaiian Homelands)
•
•

Only if there are area and/or hydro landmark updates.

Point Landmark Layer
•

Include a linear feature update layer with only feature segments that need to be corrected.

Area/Hydro Landmark Layer
•

These layers will help the Census Bureau resolve any questionable change polygons and establish the
correct boundary-to-feature relationships.

Feature Update Layer (only if there are feature (road, river, railroad, etc.) additions, deletions, name
changes, recodes, or address range updates)
•

These layers should only contain the complete and current boundary for the entity being updated;
and
A whole entity layer should be created for each level of geography that change polygons are being
created for.

Local Government Feature Network and Boundary Layers (optional)
•

These layers consist of the changes that the Census Bureau needs to make to entities; and
A layer of change polygons should be created for each level of geography (ANRC, AIA, Tribal
Subdivisions, etc.) that changes are being submitted for.

Only if there are point landmark updates.

Compressing the Digital Files

The SWIM requires all BAS returns to be zipped prior to submission. Please compress ALL update
materials (including change polygon shapefiles, whole entity shapefiles, linear feature updates,
landmark updates, local government feature network and boundary layers, any necessary supporting
documentation (e.g., trust deeds), and the text or other file with your updated BAS contact information).
1. Navigate to the directory with the shapefiles.
Note: Centerline files or any additional information that may be helpful for the Census Bureau to process your file
is optional. One example where this would be helpful is if a particular polygon was not snapped to a river or
road because the boundary does not follow the river or road.
2.

Select all files and right click on the selection.

Select WinZip, and then Add to Zip file.

Figure 19. Selecting and Zipping Return Files
Note: Versions of WinZip may vary so the interface may be slightly different. Software other than WinZip may be
used to zip the return files.

Additional Information

The Census Bureau recommends using Federal Information Processing Standards (FIPS) codes to identify
entities such as counties, AIAs, etc. Using a standard coding scheme facilitates the digital exchange of
data.
The Census Bureau includes these codes in the BAS shapefiles. Online, you can find the codes at
. If there are any questions or problems,
contact the Census Bureau at 1-800-972-5651 or [email protected].
Due to limited staff, the Census Bureau may not be able to make all updates this year. The Census
Bureau will prioritize updates in the following order: legal changes, boundary corrections, linear feature
changes, and landmark changes. The earlier the Census Bureau receives a submission, the greater the
chance that the Census Bureau will be able to make all of the updates. Only submit changes that
occurred on or before January 1, 2018. The Census Bureau will not be able to make any updates
effective after this date until next year’s BAS.

APPENDIX B 2018 Digital BAS – Example Process 1
B.1

Required Census Bureau Shapefiles

When downloading shapefiles for the 2018 BAS, shapefiles will begin with the prefix PVS
(e.g., PVS_18_v2_edges_.shp). Throughout this guide, Census Bureau uses the prefix of
bas_2018, but the PVS files are exactly the same.
Note: Contact the Census Bureau at 1-800-972-5651 or [email protected] with any questions.

Copy the data to a hard drive/server, and unzip the data to ensure that the correct data was
downloaded. For an AIA, these layers are critical:
•

PVS_18_v2_aial_.shp

•

PVS_18_v2_edges_.shp

Note: represents the two-digit state code and three-digit county code.

The shapefiles should include the home county/counties for all reservations and off-reservation trust
lands as well as all adjacent counties.

Note: Census Bureau suggests that participants make an extra copy of the data as an emergency backup.

B.2

Symbolizing Layers in ArcGIS

The following are suggestions for symbolizing Census Bureau data in ArcGIS. For the Edges layer,
symbolize the linear features by grouping like MTFCC codes (codes sharing the same first character). See
Table 24.

Reviewing and Attributing Change Polygons

After the individual change polygons have been created, each must be reviewed and appropriately
coded. When reviewing the polygons, please refer to Section 5.3 in the main part of this guide to look
for polygons that should be deleted from your submission as well as those that should be snapped to
nearby visible features to maintain boundary-to-feature relationships.

B.7.1

Examples

These examples show very small sliver polygons that should be deleted during review as they eliminate
boundary-to-feature relationships with a river (left) and a road (right). Furthermore, these boundary
corrections also are not located near legal changes or corridor/offset changes (type ‘A’, ‘D’, ‘C’, ‘F’), so
they should be removed from consideration.

Required Census Bureau Shapefiles

•

When downloading shapefiles for the 2018 BAS, shapefiles will begin with the prefix PVS
(e.g., PVS_18_v2_edges_.shp).

•

Throughout this guide, Census Bureau uses the prefix of bas_2018, but the PVS files are exactly the same.

Note: Contact the Census Bureau at 1-800-972-5651 or [email protected] with any questions.

Copy the data to a hard drive/server, and unzip the data to ensure that the correct data was
downloaded. For an AIA, these layers are critical:

•
•

PVS_18_v2_aial_.shp
PVS_18_v2_edges_.shp

Note: represents the two-digit state code and three-digit county code.

The shapefiles should include the home county/counties for all of your reservation and off-reservation
trust lands as well as all adjacent counties.

Note: The Census Bureau suggests that participants make an extra copy of the data as an emergency backup.
