Request for Non-Substantive Change to the
Boundary and Annexation Survey
OMB Control No. 0607-0151
U.S. Department of Commerce
U.S. Census Bureau
Purpose
The U.S. Census Bureau offers the Boundary and Annexation Survey (BAS) as an annual
opportunity for tribal, state, and local governments to submit updates for federally recognized
American Indian areas, tribal subdivisions, incorporated place boundaries, minor civil divisions,
and counties.
This non-substantive change request is to update the BAS respondent guides to reflect software
updates and new tools available for respondents, as well as cosmetic and formatting changes.
The updated respondent guides include:
• BAS Digital
• BAS Digital Geographic Update Partnership Software (GUPS)
• BAS Digital Quick Start
• BAS GUPS Quick Start
• BAS Paper
• BAS Tribal GUPS
• BAS Digital Tribal
Background
The current BAS OMB collection was approved on 11/7/2018 for three years with an expiration
date of 11/30/2021. This non-substantive change is a request to submit revised copies of seven
respondent guides that will be used in the 2019 BAS materials. The Census Bureau has made
some changes to the respondent guides to include a new partnership toolbox that automates a
part of the digital response process. The respondent guides also have updated instructions on
using the Secure Web Incoming Module (SWIM), which is a secure file transport protocol
through which they can submit digital responses.
There are no substantive changes to the program resulting from this change.
Burden
The burden of the BAS is unchanged by this update.

INTRODUCTION
A.

The Boundary and Annexation Survey

The U.S. Census Bureau (Census Bureau) conducts the Boundary and Annexation Survey (BAS)
annually 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, and Hawaiian Homelands. 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 BAS to tabulate data for the
decennial and economic censuses, and to support the yearly delivery of the Population
Estimates Program (PEP) and the American Community Survey (ACS) data. Maintaining correct
boundaries and boundary-to-feature relationships through BAS helps ensure that the Census
Bureau assigns the appropriate housing and population counts to each governmental unit (GU).
In compliance with the Office of Management and Budget Circular A-16, 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, 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, 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 website at .
For more information on BAS, please view the “Introduction to BAS” video series on the Census
Bureau’s BAS website at .

What's New for the 2019 BAS?
1. The Census Bureau developed a BAS Partner Toolbox for ArcGIS users. This toolbox is designed
to simplify and standardize the BAS update process. See Appendix Afor a step-by-step guide to
using this new tool.
2. The GUPS help videos previously embedded in the software are relocated to the BAS website.
3. Redistricting data contacts participating in the Voting District Project verification phase may
submit boundary updates for reconciliation with BAS contacts.
4. Website revisions.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital viii

Key Dates for BAS Respondents

January 1—Boundary changes must be legally in effect on or before this date to be reported in
the current survey year.
March 1—Boundary updates returned by this date will be reflected in the ACS and PEP data
estimates, and in next year’s BAS materials.
May 31—Boundary updates returned by this date will be reflected in next year’s BAS materials.

BAS State Agreements

The Census Bureau established a number of agreements with states for reporting boundary
changes. Please visit the BAS State Agreements webpage within the BAS program website 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 until there is a documented final court decision regarding the
dispute.
To learn more, 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
1. 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).
2. 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.
3. All participants must provide legal documentation numbers and effective dates for all legal
boundary changes (annexations and deannexations).
4. 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.

1.2

Using SWIM to Submit Changes to the Census Bureau

All participants must use SWIM to submit their changes to the Census Bureau. Due to security
requirements, the Census Bureau cannot accept submissions via FTP, email or any protocol
other than the SWIM site. For details on registering and using SWIM, please see Section 5.7.6
Submitting Digital Files via SWIM. To access SWIM, enter the following URL in a new browser
window: .To access SWIM, enter the following URL in a
new browser window: .

1.3

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
website at: .
If there are any questions or concerns about the participation requirements, contact the Census
Bureau at 1-800-972-5651 or [email protected].
For participants already familiar with GIS and BAS updating procedures, Appendix Aand
Appendix Cprovide step-by-step guidelines for making updates.

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.

2.1

Topological Relationships in MAF/TIGER

At the Census Bureau, topology is described 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 Three 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.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital 2

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.

2.2

GIS and Spatial Accuracy

In a GIS, feature classes are often not topologically integrated; they are separated into individual
layers. When these layers are overlaid 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. Overlay of Four Feature Classes and Figure 4. GIS Place Boundary Does Not Follow
Road Feature show how files that are not topologically integrated might appear in a GIS when
overlaid.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital 3

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 in
MAF/TIGER, 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.

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. Instructions on how to review digital submissions for small spatial
boundary corrections can be found in Part 5 Updating the Census Bureau Shapefiles, Section
5.6. It also lists some of the potential consequences of making spatial boundary corrections that
dissolve the topological relationships present in MAF/TIGER.
To find examples of suggested methods for correctly making boundary changes, please see
Appendix Aand Appendix C.

PART 3 CENSUS BUREAU PROVIDED SHAPEFILES
Please download shapefiles from the BAS website at:

in order to review the boundaries and submit changes.
The Census Bureau provides entity layers in ESRI shapefile format for download via the BAS
website. 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 (MSP) 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
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.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital 7

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 frontlot-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 5.8 Geographic Corridors and Section 5.9 Geographic Offsets of this document for
more details).

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 Aand Appendix Cand
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 (partnership verification shapefiles) 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 ArcGIS, use its Project tool in ArcToolbox.
MAF/TIGER shapefile extracts contain defined projection information in the *.prj file. ArcGIS
accesses 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 Aand Appendix Cprovide 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 5.13
Additional Review Information).
If additional shapefiles are needed, please contact the Census Bureau at 1-800-972-5651 or
[email protected].

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital 9

5.3.1 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 30 feet of
that feature.
Note: Enter the name of the jurisdiction annexing or deannexing the area in the NAME field.

5.3.2 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.
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:
U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital 10




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 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 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; or
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 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].

types, an individual change polygon must be created each disincorporation and must possess
the required attributes. The corresponding change type must be populated as in (see Table 5).

5.3.5 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 (shown in color)
created where the incorporated place owns the right-of-way but the housing units are not
included in the incorporated place.
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.

5.3.6 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.

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.

5.4

Linear Feature Updates

5.4.1 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 8. In the
TLID (TIGER/Line ID) field, preserve the existing TLID for the feature.





If a road, subdivision, etc. is missing from the Census Bureau’s feature network, add the
feature(s) and provide the name and MTFCC.
If a feature that does not exist is in the Census Bureau’s feature network, delete the feature.
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.

5.4.3 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 the
Census Bureau outgoing shapefiles, it is recommended that participants generally only add
address ranges to new features (see Table 9).

Area Landmarks, Hydro Areas, and Point Landmarks

5.5.1 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.

5.6

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:
.

5.6.1 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.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital 18

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.

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.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital 19

Figure 14. Small Spatial Correction Not Incorporated
Small spatial boundary corrections would dissolve the relationship with the
river. These boundary corrections will not be incorporated into
MAF/TIGER.

Figure 15. Small Spatial Correction Not Accepted
Small spatial boundary corrections would dissolve the boundary-to-feature
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.

5.6.2 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.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital 20

Figure 16. Large Boundary Corrections
Without the appropriate documentation, the 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.

5.6.3 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 5.4 Annexations
and Deannexations for the required attribute information and corresponding change type
codes.

5.6.4 Including Appropriate 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.

5.6.5 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.

roads to the existing road features.

5.7

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.

5.7.1 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:
1. 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.
2. 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.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital 22

3. Local Government Feature Network, Parcel, and Boundary Layers (optional)
 These layers will help the Census Bureau resolve any questionable change polygons and
establish the correct boundary-to-feature relationships.
4. 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.
5. Area/Hydro Landmark Update Layer
 An area/hydro landmark update layer should be submitted only if there are area and/or
hydro landmark updates.
6. Point Landmark Update Layer
 A point area landmark update layer should be submitted only if there are point landmark
updates.
7. BAS Contact Text File (if the BAS point of contact (the person that receives the BAS Annual
Response Email) has changed);
 This can be updated online at:
; and
 This update should include this information:
o First Name;
o Last Name;
o Department;
o Position;
o Shipping Address;
o City;
o State;
o ZIP Code;
o Phone: xxx-xxx-xxxx;
o FAX: xxx-xxx-xxxx;
o Email;
o HEO Term Expires: mm/yyyy; and
o HEO Term Length: x years.

5.7.5 Compressing the Digital Files
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 the participant’s updated BAS contact information).
Note: Centerline files or any additional information that may be helpful for Census to process the
participant’s 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.
1. Navigate to the directory with the shapefiles.
2. Select all files and right click on the selection.
3. Select WinZip, and then Add to ZIP file.

5.7.6 Submitting Digital Files via SWIM
The Secure Web Incoming Module (SWIM) is a one-stop location for submitting 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 submissions as an email attachment, as the Census Bureau cannot accept them
due to security policy.
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.
This token is good for one personal account within the SWIM. Once participants have registered
for an account in SWIM, they will no longer need the token to login into the system. If
participants require additional individual SWIM accounts within their organization, please
contact the Census Bureau at 1-800-972-5651 or email [email protected].
Current SWIM Users
If participants are participating in other Census Bureau partnership programs, or have participated in
previous BAS years and already have SWIM accounts, they may use their current account to submit files
for BAS. They do not need to set up a new account.
Participants will not be able to upload a file larger than 250 MB.
SWIM blocks participants from uploading a ZIP file that contains another ZIP file.

At this time, SWIM only accepts ZIP files. Please zip all update materials (e.g., spatial updates
and other relevant update documents) into one ZIP file for the entity’s submission, and follow
the instructions listed below:
1. In a web browser, navigate to .
2. Login:
a) New Users: Participants must have a registration token to create a new account. (Please see
above). Once participants have their token, they should sign-up by clicking the ‘Register
Account’ button. Registration is self-serve, but does require the new user to enter a
registration token to validate their rights to the system.
b) Existing Users: If participants already have a registered account from a previous BAS year,
they should login with their user credentials.

APPENDIX B 2019 DIGITAL BAS EXAMPLE PROCESS 1
B.1

HOW-TO USE THE PARTNERSHIP TOOLBOX

In an effort to ease the burden of BAS updating for the Census Bureau’s partners, the Census
GEO BAS team developed a Toolbox for ArcGIS. This plug-in facilitates the updating process by
automating the downloading of data, creating changes, removing slivers, formatting and
checking attribution, and preparing/exporting files for submission.

B.2

TOOLS SETUP

These tools were designed primarily for use in ArcCatalog though they could be run from
ArcMap as well. The instructions for most steps are assuming use from ArcCatalog.
1. Unzip the Digital BAS Partnership Tools.ZIP to the C: drive or other preferred working
folder. It does not matter where the older is stored as long as it can be located. Inside
there will be a folder called DBAS, containing all the files to work with. Open ArcCatalog
and connect to a folder if need be. When expanded, the following should be visible:

Note: To connect to a folder in ArcCatalog, click on the Connect to Folder button on the Standard
Toolbar, find the DBAS folder, and then click OK.

B.3

RUN DATA DOWNLOAD

The Census Data Download tool will gather all the partnership shapefile data needed to create
changes from the Census website. If the data is on a Census provided disc, this tool will also
work but only if the disc is loaded into the computer before running the tool.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital

B-1

1. Expand the DBAS folder and the setup subfolder. In the setup folder, find the
Partnership toolbox. Expand the toolbox and double click on 1) Census Data Download.

2. In the User’s BASID field, enter the BASID for the entity to be processed.

3. When this tool is complete, there should now be a folder for the BASID in the projects
folder. Inside that folder, there will be a geodatabase with reference data in it and an

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital

B-2

archive folder.

Note: The archive folder contains other Census data that may be useful as well.

B.4

CREATE CHANGES

Once the necessary Census data is obtained, run the 2) Create Changes tool to make the change
polygons.
1. Double click on 2) Create Changes.

2. In the Create Changes window:
 In the Local Boundary File field, enter the path to full boundary polygon
 Enter the 11 digit BAS ID in the BAS ID field
 Under Changes Being Processed, chose the type of changes to create from the
dropdown options:
a. Incplace
b. County
c. Cousub (county subdivisions)
d. Aiaanh (Tribal areas)
 For the Name Field in local data, the boundary file may need to be modified to
match a field in the Census Bureau’s data. Type the name of the field (as it
U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital

B-3

appears in ArcCatalog) containing the information matching the Census Bureau’s
NAME field. If processing a cousub or aiaanh file where the Census Bureau NAME
field contains duplicates, match the Census Bureau’s NAMELSAD for the entities
where they have unique names

3. Once the tool is complete, the output will be placed in the geodatabase under the
submission feature dataset.

B.5

SLIVER BLASTER (OPTIONAL)

Boundary and Annexation Survey Respondent Guide: Digital

B-4

than that threshold. Participants can also change the tolerance for the sliver blaster if they
know there are small changes that need to be included.
1. Double click on 3) Sliver Blaster.

2. In the Sliver Blaster window:
 The Changes File refers to the changes file created in the previous step, found in the
submission feature dataset
 The Census Edges feature class is found in the benchmark feature dataset and is
called bas_edges

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital

B-5



B.6

The Buffer Distance field is set to 30 feet by default, but this can be adjusted to
accommodate smaller changes

FORMAT WORKING MXD (OPTIONAL)

The intent of this tool is to create a map document (.mxd) for users containing their change file
and all of the reference layers they will need to finalize a submission. If they would prefer to
use their own .mxd, this step is not required.
1. Double click on 4) Format Working MXD.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital

B-6

2. The only input for this tool is the Working Folder, which is the folder with the
participant’s BAS ID as its name.

3. Open the new .mxd and begin working with the change polygons.

B.7

ATTRIBUTE CHECK

This tool is used to verify that there are no inconsistencies with the data included in the
submission. This tool can be run during or after change polygons have been reviewed for spatial
accuracy to produce a report of attribution errors. It may also be run for all levels of geography
that have changes since it is run on each individual change file.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital

B-7

1. Double click on 5) Attribute Check.

2. In the Attribute Check window:
 The Change File should be the change file created in tool 2) Create Changes for
which to generate a report
 In Geography Type, chose the type of geography being worked on from the
dropdown. The same options as the Create Changes tool are available here
 The last input is the optional check box for Includes Changes in Georgia. This box
only needs to be checked if responding in the state of Georgia

3. There should now be a text file in the working folder called
attribute_check_ containing all discrepancies identified in the change file
that still need to be fixed

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital

B-8

B.8

EXPORT SUBMISSION

Upon review of the changes file and the attribute error report, the finalized changes can be
exported for submission to the Census Bureau. This tool can also be used to provide updated
contact information with the submission.
1. Double click on 6) Export Submission Files.

2. In the Export Submission Files window:
 Under Files to submit, add as many changes files as needed to update the
boundaries
 For BAS Contact, Entity Name, Contact Title or Department Name, Address,
Email, and Phone Number, please include any or all contact information updates
that are to be sent to the U.S. Census Bureau. These fields can be left blank if
there are no updates, though if someone other than the BAS Contact prepared
the submission, they may want to include their information

SUBMITTING TO SWIM

The Census Bureau requires participants submit BAS return ZIP files using the Census Bureau’s
SWIM site. Please submit only the ZIP file. SWIM is located at
. For instructions on how to use SWIM, see Section 5.7.6 of
the respondent guide.

APPENDIX C 2019 DIGITAL BAS EXAMPLE PROCESS 2
C.1

REQUIRED CENSUS BUREAU SHAPEFILES

When downloading shapefiles for the 2019 BAS, shapefiles will begin with the prefix PVS
(partnership verification shapefiles) (e.g., PVS_18_v2_edges_.shp). Throughout this
guide, Census Bureau uses the prefix of bas_2019, 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.

C.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
multi-part 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.

C.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.

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.

C.8

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 Boundary
Changes in the main part of this guide to look for polygons that should be deleted from the
submission, as well as those that should be snapped to nearby visible features to maintain
boundary-to-feature relationships.

C.9

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.

The examples in Figure 38 show small slivers along rivers (left) or roads (right) that should be
deleted.

a waterbody in a boat.
A legal/statistical boundary line that does not correspond to a
shoreline or other visible feature on the ground.
The more-or-less permanent boundary between land and water for a
water feature that exists year-round.
The boundary between land and water (when water is present) for a
water feature that does not exist year-round.
A bounding Edge that does not represent a legal/statistical boundary,
and does not correspond to a shoreline or other visible feature on the
ground. Many such Edges bound area landmarks, while many others
separate water features from each other (e.g., where a bay meets the
ocean).
A line of fixed rails or tracks that carries mainstream railroad traffic.
Such a rail line can be a main line or spur line, or part of a rail yard.
Mass transit rail lines (including lines for rapid transit, monorails,
streetcars, light rail, etc.) that are typically inaccessible to mainstream
railroad traffic and whose tracks are not part of a road right-of-way.
A special purpose rail line for climbing steep grades that is typically
inaccessible to mainstream railroad traffic. Note that aerial tramways
and streetcars (which may also be called “trams”) are accounted for by
other MTFCCs and do not belong in R1052.
Primary roads are generally divided, limited-access highways within the
interstate highway system or under state management, and are
distinguished by the presence of interchanges. These highways are
accessible by ramps and may include some toll highways.
Secondary roads are main arteries, usually in the U.S. Highway, State
Highway or County Highway system. These roads have one 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 has a
single lane of traffic in each direction. Roads in this feature class may
be privately or publicly maintained. Scenic park roads would be
included in this feature class, as would (depending on the region of the
country) some unpaved roads.
An unpaved dirt trail where a four-wheel drive vehicle is required.
These vehicular trails are found almost exclusively in very rural areas.
Minor, unpaved roads usable by ordinary cars and trucks belong in the
S1400 category.
A road that allows controlled access from adjacent roads onto a limited
access highway, often in the form of a cloverleaf interchange. These
roads are unaddressable and do not carry a name in the MAF/TIGER
System.
A road, usually paralleling a limited access highway, that provides
access to structures along the highway. These roads can be named and
may intersect with other roads.
A path that is used for walking, being either too narrow for or legally
restricted from vehicular traffic.
A pedestrian passageway from one level to another by a series of
steps.
A service road that does not generally have associated addressed

PART 2: HOW TO USE GUPS
INTRODUCTION
A.

The Boundary and Annexation Survey

The U.S. Census Bureau conducts the Boundary and Annexation Survey (BAS) annually 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, and
Hawaiian Homelands. BAS also provides an opportunity for participants to review the names
and geographic relationships for these areas. Title 13, United States Code (U.S.C.), Section 6,
authorizes this survey.
The Census Bureau uses the boundary information collected during BAS to tabulate data for the
decennial and economic censuses, and to support the yearly delivery of the Population
Estimates Program (PEP) and the American Community Survey (ACS) data. Maintaining correct
boundaries and boundary-to-feature relationships through the BAS helps ensure that the
Census Bureau assigns the appropriate housing and population counts to each governmental
unit (GU).
In compliance with the Office of Management and Budget Circular A-16, 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, 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, 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 website at .
For more information on BAS, please view the “Introduction to BAS” video series on the Census
Bureau’s BAS website at .

What's New for the 2019 BAS?
1. The Census Bureau developed a BAS Partner Toolbox for ArcGIS users.
2. The GUPS help videos previously embedded in the software are relocated to the BAS website.
3. Redistricting data contacts participating in the Voting District Project verification phase may
submit boundary updates for reconciliation with BAS contacts.
4. Website revisions.

Key Dates for BAS Respondents

January 1—Boundary updates must be legally in effect on or before this date to be reported in
the current survey year.
March 1—Boundary updates returned by this date will be reflected in the ACS and PEP data
estimates, and in next year’s BAS materials.
May 31—Boundary updates returned 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 website 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.
To learn more, 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 website: . 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

PART 1: BAS OVERVIEW
SECTION 1: PROCESS AND WORKFLOW
Figure 1 below illustrates the three phases of the work to be completed for the BAS. The first
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

The sections 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

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital GUPS

PART 1: BAS OVERVIEW
Once GUPS is installed, the BAS shapefiles can be imported from the BAS website directly to the
GUPS application. Instructions on how to load data into GUPS appears in Section 5.2. If a
participant does not have Internet access, they may request shapefiles on DVD. To request a
data DVD, call (800) 972-5651 or email [email protected].

1.2

Getting 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.).

1.2.1 GUPS Help
Training videos for help with using GUPS are available on the BAS website
. In addition, a Section
508-compliant version of this guide is available there.
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 via telephone at (800) 972-5651 and by email [email protected].

1.2.2 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 Bureau 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,

PART 1: BAS OVERVIEW
SECTION 2: REVIEWING BAS DATA
The Census Bureau requests that participants review and update all legal entities and
boundaries within their jurisdiction, including the new incorporation or disincorporation of legal
entities, legal boundary changes, and boundary corrections. They may also update linear
features and landmarks, including area landmarks, hydrographic areas, and point landmarks,
although review of these is optional.
To help conduct their review, the GUPS application allows participants to import and overlay
their own geospatial data layers with the Census Bureau shapefiles. Image files may be
imported from web mapping services, geodatabases, and 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.

2.1

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 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, participants should examine the Census Bureau shapefiles
for all legal entities within their jurisdiction. These include:





Incorporated places;
Minor Civil Divisions (MCDs) such as towns, boroughs, and townships;
Counties (and county equivalents); and
Consolidated cities.

Table 1 shows the specific changes allowed for each legal entity type.

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, participants must provide the legal
documentation number (e.g., law or ordinance number), effective date, and authorization type.
They are not required to submit paperwork documenting the change.
Note: Although additional documentation is not required, the Census Bureau strongly encourages
attaching supporting paperwork to submissions (this may be done directly in GUPS). The
paperwork will expedite the Census Bureau’s ability to reconcile and process any legal updates.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital GUPS

PART 1: BAS OVERVIEW
2.4.2 Boundary Changes to Legal Entities in Georgia and Indiana
For questions about required documentation for a particular jurisdiction, contact the
Geography Division by phone at (800) 972-5651 or by email at [email protected].
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, 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: .
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
.

Legal Disputes

2.6

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).
Attribute updates (e.g., name, class code, and address ranges) may also be added 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 users to import local street centerline files,
hydrography layers, imagery, and other user-provided geospatial data for reference and
comparison against the Census Bureau data.

PART 1: BAS OVERVIEW
In the review, please note:





2.7

S1100 and S1200—If adding road features with an MTFCC of S1100 (Primary Road) or S1200
(Secondary Road), users 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, the required attributes and
corresponding change type for the update must be supplied. In addition, because existing
address ranges are not shown in the Census Bureau’s outgoing shapefiles, it is recommended
that participants only add address ranges to new features.

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;
Change or add landmark name; and
Boundary corrections (add and remove area).

If adding 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.

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.
The Census Bureau is working on incorporating those changes, and they will be reflected in the next
year’s BAS materials.

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 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.

SECTION 3: QUALITY CONTROL AND FILE SUBMISSION
3.1

Validating Updates

Validate Often
Validation tools in GUPS can be accessed at any time while working in the application. For best results,
utilize the tools often while working 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 the BAS
team to review the files early, provide feedback, and avoid backups in file processing—and the
participant—guaranteeing their 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, the Census Bureau cannot accept files sent via email
or through its alternate ftp sites.
If participants indicated on their “Annual Response Form” that they wished to receive the GUPS
application, they 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).
The registration token allows users to establish personal SWIM accounts. If a SWIM token does
not arrive after the amount of time specified, email [email protected] or call (800) 972-5651.
Once registered, the token will no longer be necessary to log into the system.

the alternate name, if one is present, in the Alt. Name field.

To see any additional alternate names, click the drop-down arrow to the right of the Alt. Name
field. If no alternate name exists, ‘NULL’ appears in the Alt. name field.
Step 2

If providing an address range for a linear feature, check the checkbox next to > direction in the
Edges field in the Table of Contents. This activates the arrows that indicate the FROM and TO nodes
for line segments.

Step 3

Click on the Modify Linear Feature Attributes button on the BAS toolbar.

Step 4

Click the linear feature on the map with attributes to be edited. The Modify Linear Feature
Attributes dialog box opens with the TIGER Line Feature ID (TLID) of the feature selected. The

FULLNAME field populates if the feature is named. If the feature is not named, the field is blank. The
MTFCC, LTOADD, RTOADD, LFROMADD, and RFROMADD fields show the assigned values for each.

Step 5

Update the FULLNAME field. If the field is blank, type in the new name. If the field is already
populated, highlight the existing name and hit the Delete key on the keyboard. It is also possible to
backspace over the name to clear the field. Then type in the new name.

Step 6

If correcting the MTFCC, 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. Address ranges can be provided in these
fields, but be aware that the Census Bureau 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.

SECTION 5: USING GUPS (BASICS AND MAP MANAGEMENT)
After successfully installing GUPS, participants are ready to start their BAS updates. There are
three ways to retrieve shapefiles when starting a new project:




From the Census Bureau website (loads directly into GUPS);
From DVD (if one was requested); and
From My Computer (if the files have been downloaded to the hard drive).

Table 7 shows the steps to open GUPS and start a new project using the Census Bureau
website. Table 8 shows the same steps to open GUPS, but starts a new project using the Census
Bureau provided DVD or My Computer (downloaded Census Bureau shapefiles saved to the
hard drive).

5.1

How to Access BAS Shapefiles

BAS shapefiles from the BAS website can be pulled directly into the application when working in
GUPS by choosing the Census Web option during project setup. 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 from the BAS website (or from
the Census Bureau ftp2 site), then import them into GUPS. BAS shapefiles are available for
download from the BAS website here: . Instructions for how to download Census
Bureau shapefiles appear in Table 7 and Table 8. Downloading files to the hard drive is not the
preferred method when working in GUPS, and should be used only when necessary (e.g., if
additional data layers that GUPS does not automatically load need to be pulled in as userprovided data).
If the shapefiles were requested to be received on a DVD, the files can be loaded directly into
GUPS from the DVD. Instructions for how to load shapefiles are contained in Table 7: Start a
New Project Using Shapefiles from the BAS website.
Whether the files are pulled from the BAS website or from the DVD, the GUPS application
unzips them and places them into a pre-established folder created on the computer’s home
directory during the installation process (C:\GUPSGIS\gupsdata\BAS2019\shape). It then
displays them in the application and manages the files. There is no need to take any further
action.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital GUPS

PART 2: HOW TO USE GUPS
CAUTION!
Regardless of the source of the shapefiles, it is important NOT TO 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.

5.2

Import Data from the Census Bureau’s BAS Website

To open the GUPS application and begin BAS updates, follow the steps in Table 7 below. Before
beginning, note that:
1. To practice using GUPS without committing the changes, simply exit the system without saving.
Before the system closes, it will give the option to discard the changes.
2. If comfortable with the system, but not all changes are completed in one session, simply save
the changes, then close the system. When opening GUPS later, reopen the project and continue
working.
Note: In all the Action/Result tables, the action is usually a command or action to be performed and the
Result(s) of the action will be shown in italics. For example: click the QGIS icon on the desktop,
the software should begin to run automatically.

After selecting the working county, GUPS will prompt the participant for a location from which to
import the county’s (or county equivalent’s) shapefiles. The Select Data Folder, Directory or Location
box opens.

GUPS only asks to specify a data download location once per project. When a project has been closed
and reopened, the shapefiles automatically load, even if no changes were made during the first
session.
Step 9

Step 10

When Census Web is chosen, 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

As GUPS loads the data, it unzips and copies the files to a folder in the home directory created during
the installation process. The data is then loaded into the GUPS application.

Step 12

After the files load, GUPS returns to the Map Management screen. In the Entity Type field drop-down
menu, select the type of entity to be updated. The options are ‘Consolidated City’, County’, ‘Minor
Civil Division (MCD)’, ‘Place’, and ‘State’.
Note: The options may vary, depending on the entity types the state contains. Independent city
users should select ‘Place’.
This example assumes a ‘County’ user.

Step 13

U.S. Census Bureau

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

the Entity Name field with ‘Jefferson County.’

If ‘Consolidated City’ was selected as the Entity Type, the name of the consolidated city-county
government automatically fills the Entity Name field.
If ‘Place’ was selected as the Entity Type, the Entity Name field is blank. A drop-down menu, which
lists all incorporated places within the working county, allows selection of the correct entity.
If ‘State’ was selected as the entity type, the state 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
may be checked if necessary.

Step 15

All checked counties will display in the Map View. Uncheck the box for any county in order to not
display it.
To select additional counties to display (up to a total of 10 may be chosen 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 25

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 a list of current projects.

If sharing a computer with other GUPS users, multiple project files may appear in the drop-down
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 a particular project, look at its number string.
This string comprises a 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.

After identifying 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 a new project is started
in GUPS. If these default settings have been changed and then are saved during a project, reopening
the project will load these saved changes rather than the Census Bureau-defined default layers and
view setting.

5.6.2.2 Select/Deselect Features Using the Select Features and Deselect Features Buttons
The Select Features button provides several ways to select features on the map. The Deselect
Features from All Layers button allows users to deselect previously selected features.
Table 15 describes each of the feature selection methods, discusses when one might be
preferable over another, and explains how to deselect features.

Step
Step 1

Action and Result
To begin, click on a layer name in the Table of Contents. For example, to select a linear feature, click
on the ‘edges’ layer. 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, select ‘faces’ in the Table of
Contents and click 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 face(s). This
method is useful when selecting noncontiguous faces, as shown below.

To select multiple features, click the Select Feature button, then drag the cursor over the features on
the map. This method is useful when selecting a large number of contiguous faces or a large number
of nearby linear features without having to click each feature one by one.
A Note on GUPS Tools
GUPS tools remain active until a different tool is selected. For example, if the Select Features tool is
used to choose faces for a new area landmark, then in order to add a new linear feature instead, the
Add Linear Feature tool must be clicked before clicking on the map again. If not, the Select Features
tool, still active, selects a face.

Step 10

Action and Result

The third option, ‘Select Features by Freehand’, selects features based on user-defined shapes drawn
on the map.

To use this option, click on the map and use the 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. For example,
draw a tiny triangle within a face to select it.
Step 11

The final option, ‘Select Features by Radius,’ selects features by defining a circle around the features
to select.

Polygons can be deselected by holding and using the same selection option to select 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.

Next, go to the map and place the cursor where the faces are to be added.
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, seven faces were
selected. The faces selected turn cyan blue (color may vary).

Because all geographic areas consist of faces, one 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 34 for
instructions to add a linear feature) and assign it the appropriate MTFCC. This splits the original face
into two faces. The new face can now be added to the new entity.
If a face is accidentally selected, it can be deselected with the Deselect Features from All Layers
option in the Select Feature(s) drop-down menu.

6.1.6 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 31 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, to annex land from another entity within the consolidated government
area, treat it as one would any annexation within a county.

How to Use GUPS Review and Validation Tools

GUPS provides two tools—the Geography Review tool and the Review Change Polygons tool to
help users review and validate the updates 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.
This tool can check the changes made to linear features, area landmarks, point landmarks, and
legal boundaries anywhere within a county. It can also be used to view the attributes of
entities, features, landmarks, and boundaries not changed. Note: Although this tool allows
users to review changes, it cannot be used to edit them. Instructions for how to use the
Geography Review tool information appear in Table 45.

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 one will receive a blank box
in which they may type the search value. For example, if filtering the area landmarks layer by
MTFCC and one wants to see hospitals in the layer, type in the MTFCC for hospitals (K1231), as

6.5.2 Review Change Polygons Tool
The Review Change Polygons tool allows users to view the transactions created from the edits
made to legal entities, as well as to area landmarks and hydrographic areas. Users can review
the transaction polygons that represent boundary changes, as well as new incorporations and
disincorporations. The tool also allows users to make corrections to change polygons.

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

To use the Review Change Polygons tool, follow the steps in Table 46.
Table 46: Reviewing Change Polygons
Step

Action and Result

Step 1

In the Map Management dialog box, make sure the county for which the check is to be run
appears in the Working County field.

Once the Open button at the bottom of the dialog box is clicked and the map opens in Map
View, the Review Change Polygons check is ready to run.
If changes in more than one county were made, the check must be run for each county worked.
This means that after completing the check for one county one must return to Map
Management and select the additional county which was worked as the working county. Then
run the check on it. Repeat this process until the check is run for all counties in which changes
were made.
If no changes were made in another county, only run the check for the one county worked.
Step 2

Once the working county is loaded, begin the change polygons review.

APPENDIX B 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 lone 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 (two-dimensional
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-of-way,
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
U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital GUPS

B-1

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. One 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 one 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 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
U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital GUPS

B-2

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 16. A Cadastral (Parcel-Based) Boundary Map

Figure 17. How a Boundary Should be Represented When Sent to the Census Bureau

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Digital GUPS

B-3

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 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_2019_offset_.shp), so that a 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 Correction
1) Compare the Census Bureau’s representation of the participating government’s
Geographic Corridor
boundary with the local representation of the boundary, and extract the
differences (change polygons). The differences can be extracted using one of the
Deannexation
sample methods in the BAS Respondent Guide: Digital, or using other GIS
methods.
New Incorporation
2) Populate the applicable mandatory fields for each change polygon. The Census
Geographic Offset
Bureau may not be able to accept changes without the appropriate attribution
or documentation.
Disincorporation
 NAME: Entity name (all changes)
Authorization Types
 CHNG_TYPE: Type of area update; see tables (all changes)
 AUTHTYPE: Authorization type; see tables (all legal changes – annexations,
Ordinance
deannexations, new incorporations, disincorporations)
Resolution
 DOCU: Supporting documentation (all legal changes)
 EFF_DATE: Effective date; if after Jan 1, changes will not be included in this

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 BAS Respondent Guide: Digital. 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 bas19__return.zip. should be replaced with the eleven-digit BAS
ID code (e.g. bas19_20100100000_return.zip).

The Boundary and Annexation Survey

What’s New for the 2019 BAS?
1. The Census Bureau developed a BAS Partner Toolbox for ArcGIS users. This toolbox is designed
to standardize and simplify the BAS updating process by making many updating actions easy
with the click of a button. See the BAS Respondent Guide: Digital or BAS Tribal Respondent
Guide: Digital for more information.
2. The GUPS help videos previously embedded in the software are relocated to the BAS website.
3. Redistricting data contacts participating in the Voting District Project verification phase may
submit boundary updates for reconciliation with BAS contacts.
4. Website revisions.

Key Dates for BAS Respondents

January 1—Boundary changes must be legally in effect on or before this date to be reported in
the current survey year.
March 1— Boundary updates returned by this date will be reflected in the ACS and PEP data
estimates, and in next year’s BAS materials.
May 31—Boundary updates returned by this date will be reflected in next year’s BAS materials.

BAS State Agreements

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.
To learn more, 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: 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.
2.
3.
4.

1.2

BAS-1 for Incorporated Places
BAS-2 for Counties and Equivalent Areas
BAS-3 for Minor Civil Divisions (MCD)
BAS-5 for American Indian Reservations and Off-Reservation Trust Land

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, Highest Elected Official (HEO), or
Tribal Chair (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.

PART 2: 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, and both of these involve coding an
address to a spatial polygon. One uses Global Positioning System (GPS) technology to create a
Master Address File (MAF) structure point (MSP) and the other uses address ranges for
geocoding.

2.1

Getting Started with TIGERweb

A field worker stands in front of a house or living quarters, and records the physical location
with a GPS device (Figure 1). 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 1. GPS 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 by the red
pins) can sometimes fall within the road or the road right-of-way.

2.2

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 2).

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Paper

Page 2

Figure 2. 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 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.

2.3

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 3.5.4 of this document for more details).

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Paper

PART 3: REVIEWING AND UPDATING BAS MAPS
3.1

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 boundary ring. Entities that require more than 30 boundary ring map sheets receive
only the index map. Please review Appendix C. for a further description of the map types.

3.2

Requesting Additional Maps

If an individual map sheet or full set of maps was not provided for a county, incorporated place,
minor civil division (MCD), or AIA where boundary changes or feature updates need to be
made, please call (800) 972-5651 or e-mail [email protected] to request the additional
materials. Do not make updates on the index map.

3.3

Reviewing Boundaries with Imagery in TIGERweb

Governments that have requested paper maps can use the TIGERweb
for a more detailed
version of their boundaries with imagery before annotating the paper maps. Instructions for
using BAS TIGERweb can be found on the BAS TIGERweb website at
.

3.4

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 1 of the current survey year.
3. Annexations and deannexations from previous years may be provided in addition to updates as
of January 1. 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 3. Shared Boundary
The combined line represents a county, incorporated place, and CDP
boundary.

Boundary and Annexation Survey Respondent Guide: Paper

3.5

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 number1.Level Change
A level change occurs when a school district changes classification; for example, changing from
elementary to unified. Contact the Census Bureau for assistance in documenting this change.

3.5.1

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 deannexation 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
Draw “Xs” 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
“Xs”.

3.5.2

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 shows a change to the boundary where only the boundary moves as well as the
accompanying Documentation of Changes. Similarly, the left image of Figure 7 illustrates a
change where only the boundary moves, but the right image shows a boundary change where
the 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.

Figure 6. Annotating a Legal Boundary Change
Annotating a legal boundary change coincident with a river feature,
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. The legal change is recorded in the
Documentation of Changes. Left: Only the boundary moves to the new
location. The street feature location is correct, but the boundary
location is incorrect. Right: Both the boundary and the street feature
move to a new location. Both the boundary and the street feature
location are incorrect.

3.5.3

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.


Using the red pencil, cross out the incorrect boundary with a string of “Xs”.



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.

Incorporated Place Boundary

3.5.4

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 9. Geographic Corridor and Geographic Offset
The image on the left 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. The
image on the right 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.

3.5.4.1 Geographic Corridors
Figure 9 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:
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 10 below shows a case where the right-of-way belongs in the unincorporated area, while
the housing units in Figure 11 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
U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Paper

Page 8

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 10. Where the Right-of-way Belongs in the Unincorporated Area
Figure 11. 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 the participant’s
governmental unit. To indicate a geographic corridor on the 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 12). 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.”

Figure 12. Indicating a Geographic Corridor by Using a Red Pencil
To indicate a geographic corridor on the 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.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Paper

Page 9

3.5.4.2 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 its 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 13 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 14, 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.

Figure 13. The Place Boundary is Along the Front Lot Line
Figure 14. The Place Boundary is on the Rear Lot Line

To indicate a geographic offset on the map, use the red pencil to draw a line parallel to the
road, along which the offset will 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 15).

Figure 15. Depicting a Geographic Offset on a Paper Submission

3.5.5

New Incorporations

Newly incorporated places should provide the Census Bureau with:


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.

3.5.6

Disincorporations

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

3.5.7

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;
U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Paper

Page 11




o Health service areas;
o Emergency service delivery areas (911, fire, and/or police); or
o Grazing districts or range units.
Historical or traditional areas recognized by a tribal government.
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.
 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;
o Community;
o Area;
o Chapter;
o Segment;
o Administrative Area;
o Addition; or
o County District.

3.5.7.1 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 Bureaus’
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.

3.5.7.2 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.
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.

3.5.7.3 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 the 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.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Paper

3.5.8

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.

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 [email protected] for more information on participating in a
Consolidated BAS (CBAS) agreement or visit the Consolidated BAS website at
.

3.5.9

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
the entity’s existing or new boundaries are known to follow PLSS lines, this should be
designated on the 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, the Census Bureau will then be able to compare these lines to those shapefiles and
ensure accurate placement of the boundary.

PART 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.

4.1

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
17 and Figure 18).

Figure 17. Modifying a Street Feature, No Boundary Movement
In this example the street location moves, but the boundary does not.

Figure 18. 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.

4.1.1 Adding Streets


Using the purple pencil, please 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) (See Error! Reference source n
ot found..) for all new streets (Figure 19).



Alternate street names may be written in parentheses below the primary street name.

Figure 19. Adding an MTFCC Code When Adding a New Street

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 an alternate street name has been reported in the past, it does
not have to be reported to the Census Bureau again.

4.1.2 Adding Street Names in a Congested Area


If an area of the map is too congested to add all feature names, using the purple
pencil, 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 20).



Do not repeat numbers on a map sheet.

Figure 20. Adding Street Name Features in a Congested Area When Adding Streets

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Paper

Page 16

4.1.3 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 21. Correcting a Street Name

4.1.4 Deleting Streets


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”.

Figure 22. Deleting a Street Feature

4.1.5 Labeling Unnamed Streets


Using the purple pencil, please label any unnamed streets on the maps.



Label any unnamed private roads with “PR”. Examples of private roads are driveways and
unnamed roads in commercial or industrial parks.

Boundary and Annexation Survey Respondent Guide: Paper

Page 17

4.1.6 Adding Cul-De-Sacs or Circles


Using the purple pencil, please draw the feature as follows:
o Cul-de-sacs are entirely paved, and should be drawn as a solid dot; and
o 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.

Figure 24. Adding Cul-de-sac and Circle Features

4.2

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.

4.2.1 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 25).

4.3

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 26. Adding a Point Landmark

4.4

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.

This feature class may denote a nonvisible boundary of either public or
private lands (e.g., a park boundary) or it may denote a Public Land
Survey System or equivalent survey line.
The line that separates either land or Inland water from Coastal,
Territorial or Great Lakes water. Where land directly borders Coastal,

Feature Class Description
Mass transit rail lines (including lines for rapid transit, monorails,
streetcars, light rail, etc.) that are typically inaccessible to mainstream
railroad traffic and whose tracks are not part of a road right-of-way.
A special purpose rail line for climbing steep grades that is typically
inaccessible to mainstream railroad traffic. Note that aerial tramways
and streetcars (which may also be called “trams”) are accounted for by
other MTFCCs and do not belong in R1052.
Primary roads are generally divided, limited-access highways within the
interstate highway system or under state management, and are
distinguished by the presence of interchanges. These highways are
accessible by ramps and may include some toll highways.
Secondary roads are main arteries, usually in the U.S. Highway, State
Highway or County Highway system. These roads have one 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 has a
single lane of traffic in each direction. Roads in this feature class may
be privately or publicly maintained. Scenic park roads would be
included in this feature class, as would (depending on the region of the
country) some unpaved roads.
An unpaved dirt trail where a four-wheel drive vehicle is required.
These vehicular trails are found almost exclusively in very rural areas.
Minor, unpaved roads usable by ordinary cars and trucks belong in the
S1400 category.
A road that allows controlled access from adjacent roads onto a limited
access highway, often in the form of a cloverleaf interchange. These
roads are unaddressable and do not carry a name in the MAF/TIGER
System.
A road, usually paralleling a limited access highway, that provides
access to structures along the highway. These roads can be named and
may intersect with other roads.
A path that is used for walking, being either too narrow for or legally
restricted from vehicular traffic.
A pedestrian passageway from one level to another by a series of
steps.
A service road that does not generally have associated addressed
structures and is usually unnamed. It is located at the rear of buildings
and properties and is used for deliveries.
A road within private property that is privately maintained for service,
extractive, or other purposes. These roads are often unnamed.

APPENDIX C. READING A MAP
C.1

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 29), 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 29). 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 1:12,500.
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). The bar scale is used to determine distance on the 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
large-scale maps (see Figure 30). A map that displays a large area, but shows less detail, is
called a small-scale map. 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.

U.S. Census Bureau

Boundary and Annexation Survey Respondent Guide: Paper

C.2

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 31). 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

C.3

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 32). 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 33 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),
U.S. Census Bureau

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 highest-ranking
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.

C.4

Index Maps

In order to decide what map to use for the 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. 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, determine which parent map sheet(s) to use for the 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.

C.5

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.

Figure 36. Inset Maps
Inset maps show areas of relative congestion at a large scale, allowing a
greater amount of detail.

C.6

Parent Maps

Many entities2, 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 sheet3 (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
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
2

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

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

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 38. This key helps the user quickly determine which adjacent map sheet to use.

The key to adjacent sheets shows where the parent map sheet lies in
relation to adjacent sheets.

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.

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

INTRODUCTION
A.

The Boundary and Annexation Survey

The U.S. Census Bureau conducts the Boundary and Annexation Survey (BAS) annually 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, and
Hawaiian Homelands. BAS also provides an opportunity for participants to review the names
and geographic relationships for these areas. Title 13, United States Code (U.S.C.), Section 6,
authorizes this survey.
The Census Bureau uses the boundary information collected during BAS to tabulate data for the
decennial and economic censuses, and to support the yearly deliver of the Population Estimates
Program (PEP) and the American Community Survey (ACS) data. Maintaining correct boundaries
and boundary-to-feature relationships through BAS helps ensure that the Census Bureau
assigns the appropriate housing and population counts to each governmental unit (GU).
In compliance with the Office of Management and Budget Circular A-16, 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, 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, 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 website at .
For more information on BAS, please view the “Introduction to BAS” video series on the Census
Bureau’s BAS website at .

What's New for the 2019 BAS?
1. The Census Bureau developed a BAS Partner Toolbox for ArcGIS users. This toolbox is designed
to simplify and standardize the BAS update process.
2. The GUPS help videos previously embedded in the software are relocated to the BAS website.
3. Redistricting data contacts participating in the Voting District Project verification phase may
submit boundary updates for reconciliation with BAS contacts.
4. Website revisions.

Key Dates for BAS Respondents

January 1—Boundary updates must be legally in effect on or before this date to be reported in
the current survey year.
March 1—Boundary updates returned by this date will be reflected in the ACS data estimates
and in next year’s BAS materials.
May 31—Boundary updates returned by this date will be reflected in next year’s BAS materials.

BAS State Agreements

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.
To learn more, 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 Tribal
Respondent Guide: Digital available on the BAS website: . 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

PART 1: BAS OVERVIEW
SECTION 1. PROCESS AND WORKFLOW
Figure 1 below illustrates the three phases of the work to be completed for Tribal BAS. The first
section in the diagram includes initial steps. The second section indicates the types of
geographic data that should be reviewed and updated. The last section lists the final steps to
validate and submit changes.

Figure 1. Tribal BAS Workflow

The sections 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 website . Participants can also request to receive GUPS software
on DVD, which will be shipped in a package containing the GUPS DVD, respondent guide, and a
read me text file.
Once GUPS is installed, the BAS shapefiles can be imported from the BAS website directly to the
GUPS application. Instructions on how to load data into GUPS appears in Section 5.2.
U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

PART 1: BAS OVERVIEW
If a participant does not have Internet access, they may request shapefiles on DVD. To request a
data DVD, call (800) 972-5651 or email [email protected].

1.2

Getting 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., additions and deletions of tribal areas, adding and deleting features and
landmarks, etc.).

1.2.2 BAS Help
BAS participants may find the Boundary and Annexation Survey Tribal Respondent Guide: Digital
helpful. Although designed for experienced GIS users, it provides important information on
geocoding, topological relationships, and spatial accuracy relevant to Census Bureau 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 BAS. To view these videos, go
to: .

PART 1: BAS OVERVIEW
SECTION 2. REVIEWING BAS DATA
The Census Bureau requests that participants review and update all legal entities and
boundaries within their reservation/trust lands/tribal subdivisions, including the additions and
deletions of land area and boundary corrections. They may also update linear features and
landmarks, including area landmarks, hydrographic areas, and point landmarks, although
review of these is optional.
To help conduct the review, the GUPS application allows participants to import and overlay
their own geospatial data layers with the Census Bureau shapefiles. Image files may be
imported from web mapping services, geodatabases, and 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.

2.1

Boundary Corrections

2.2

Legal Boundary Changes

Legal boundary changes are the result of legal actions (e.g., additions), and documenting such
changes is the primary goal of 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

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.

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

PART 1: BAS OVERVIEW




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.

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,
documentation is required to update reservation and off-reservation trust land boundaries.

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

PART 1: BAS OVERVIEW
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 the 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 the reservation
document.
If no documentation is available, please contact the tribe’s 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.
For questions about documentation, please call the Census Bureau at (800) 972-5651 or email
[email protected]. To contact the BIA, please see
for regional office contact
information.

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 any boundary corrections until the parties come
to a written agreement, or there is a documented final court decision regarding the
matter/dispute. For further information, 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

PART 1: BAS OVERVIEW
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).
Attribute updates (e.g., name, class code, and address ranges) may also be added 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 users 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 the review, please note:


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 adding a new area landmark or hydrographic area, please add only:

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.
The Census Bureau are working on incorporating those changes, and they will be reflected in the next
year’s BAS materials.

3.1

Validating Updates

Once BAS updates are complete, please conduct a review of the change polygons to ensure
that:
1. The polygons have no unintended holes (e.g., several faces were annexed but missing 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 working in the application. For best results,
utilize the tools while working 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.

Step 6

To select the faces to be added 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 the “polygon” method is used to select the faces to be added to Kootenai OffReservation Trust Lands. Click on ‘Select Features by Polygon’ in the menu.

Step 7

Next, go to the map and place the cursor where the faces should be added.
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, select seven faces.
The faces selected turn cyan (color may vary).

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

PART 2: HOW TO USE GUPS
Step

Action and Result

Because all geographic areas consist of faces, it may be necessary 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 on how to add a linear feature) and assign it the appropriate MTFCC. This splits the
original face into two faces. The new face can now be added to the new entity.
If a face is selected by accident, use the Deselect Features from All Layers option in the Select
Feature(s) drop-down menu to clear the selected faces from the screen and start over.

Step 8

Click the Add Area button on the dialog box toolbar.

PART 2: HOW TO USE GUPS
SECTION 5. USING GUPS (BASICS AND MAP MANAGEMENT)
After successfully installing GUPS, participants are ready to start their Tribal BAS updates. There
are three ways to retrieve shapefiles when starting a new project:




From the Census website (loads directly into GUPS);
From DVD (if one was requested); and
From My Computer (if the files have been downloaded to the hard drive).

5.1

How to Access BAS Shapefiles

BAS shapefiles from the BAS website can be pulled directly into the application when working in
GUPS by choosing the Census Web option during project setup. 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 from the BAS website (or from
the Census Bureau ftp2 site), then import them into GUPS. BAS shapefiles are available for
download from the BAS website here: . Instructions for how to download Census
Bureau shapefiles appear in Table 7 and Table 8. Downloading files to the hard drive is not the
preferred method when working in GUPS, and should be used only when necessary (e.g., if
additional data layers that GUPS does not automatically load need to be pulled in as userprovided data).
If the shapefiles were requested to be received on a DVD, the files can be loaded directly into
GUPS from the DVD. Instructions for how to load shapefiles are contained in Table 7: Start a
New Project Using Shapefiles from the BAS Website.
Whether the files are pulled from the BAS website or from the DVD, the GUPS application
unzips them and places them into a pre-established folder created on the computer’s home
directory during the installation process (C:\GUPSGIS\gupsdata\BAS2019\shape). It then
displays them in the application and manages the files. There is no need to take any further
action.
CAUTION!
Regardless of the source of the shapefiles, it is important NOT TO 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.

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

PART 2: HOW TO USE GUPS
5.2

Import Data from the Census Bureau’s BAS Website

To open the GUPS application and begin Tribal BAS updates, follow the steps in Table 7 below.
Before beginning, note that:
1. To practice using GUPS without committing the changes made, simply exit the system without
saving. Before the system closes, it will give the option to discard the changes.
If comfortable with the system, but not all changes are completed in one session, simply save
the changes, then close the system. When opening GUPS later, reopen the project and continue
working.
Note: In all the Action/Result tables, the action is usually a command or action to be performed and the
Result(s) of the action will be shown in italics. For example: click the QGIS icon on the desktop,
the software should begin to run automatically.

If sharing a computer with other GUPS users, multiple project files may appear in the drop-down
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 the project, look at its number string. This
string comprises the 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).

U.S. Census Bureau

Action and Result
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 1750 = Karuk Reservation/Trust Land.
The BAS ID information for a particular geography is available within the Map Management
dialog box. Below is an example for Karuk Tribe Karuk Reservation.

Step 21

After identifying 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 a new project is
started in GUPS. If these default settings have been changed and then are saved during a project,
reopening the project will load these saved changes rather than the Census Bureau-defined
default layers and view setting.
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).

SECTION 6. MAKING BAS UPDATES IN GUPS
The tables in this section provide step-by-step instructions for making BAS updates. The
examples assume participants have read and understood the directions for opening GUPS and
using Map Management. If not yet comfortable with Map Management, please review the
contents of Section 5 Using GUPS (Basics and Map Management) before making updates. It is
highly recommended to use a source of imagery data when making any BAS updates.

6.1

How to Update Legal Boundaries

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.

6.1.1 Adding Land Area as Reservation or Trust Lands for the First Time
Follow the steps in the Table 26 to add land as reservation or off-reservation trust land(s). In
this example, a parcel of land is added as a fictitious newly acquired ‘off-reservation’ trust land
for the Spirit Lake Reservation (3935).
Table 26: Add Land Area as Reservation or Off-reservation Trust Land
Step
Step 1

Action and Result
Open in Map View the entity where the new trust land(s) will be added. Be sure that all layers
desired to be seen are checked in the Table of Contents. It is recommended to 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.

Step 3

U.S. Census Bureau

Click the drop-down area next to the Geography field, and select the entity type to be added from
the drop-down menu. In this example Off-Reservation trust land is being added, so
‘Reservation/Trust Land’ is selected.

Step

Action and Result

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

Double-click on the row in the list for the place that is making the annexation. (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.) The map zooms to the place selected upon double-clicking a row.

If the map does not zoom to a scale sufficient to make the changes, click on the Zoom in button on
the Standard toolbar.
Step 5

Then click on the map to select the face or faces.
If the entity includes only a single face, 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).

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

PART 2: HOW TO USE GUPS
Step

Action and Result

Note: Faces may also be selected (after clicking the Select Features button) by simply dragging the
cursor over the edges that mark their boundaries. Additional means of selecting faces (by polygon
and by radius) are discussed in Section 1.
Because all geographic areas consist of faces, it may be necessary 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 30 for
instructions on how to add a linear feature) and assign it the appropriate MTFCC. This splits the
original face into two faces. The new face can now be added to the new entity.
If a face is accidentally selected, it can be deselected with the Deselect Features from All Layers
option in the Select Feature(s) drop-down menu.

Step 6

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

In the new entity dialog box, select the LSAD (Legal/Statistical Area Description) from the drop-down
list available. This example indicates 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.

required field not completed will highlight in red.
If the reservation and/or trust lands contain more than one census tract, or more than one block
group or more than one Tribal Subdivision – there are a few additional steps – continue on to Step
15 below.
If not, and all required fields have been completed, when OK is clicked, 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 there is more than one 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 one 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 to. In this example, the new Off-Reservation Trust Land is being
assigned to Wood Lake District (800).

How to Use GUPS Review and Validation Tools

GUPS provides two tools—the Geography Review tool and the Review Change Polygons tool to
help users review and validate the updates 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.
This tool can check the changes made to linear features, area landmarks, point landmarks, and
legal boundaries anywhere within a county. It can also be used to view the attributes of
entities, features, landmarks, and boundaries that were not changed. Note: Although this tool
allows users to review the changes, they cannot use it to edit them. Instructions for how to use
the Geography Review tool information appear below.

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 a blank box will appear in
which search values may be entered. For example, if filtering the area landmarks layer by MTFCC
to see hospitals, 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 users to view the transactions created from the edits
made to legal entities, as well as to area landmarks and hydrographic areas. Users can review
the transaction polygons that represent boundary changes, as well as new incorporations and
disincorporations. The tool also allows users to make corrections to change polygons.
Notes on Reviewing Change Polygons
The Review Change Polygons tool must be run before GUPS will export a file.
The Review Change Polygons tool must be run for each county in which changes were made. For
example, if changes were made to the working county, but also to an adjacent county when annexing
land for the tribal area, the change polygon check must be run on both counties.

To use the Review Change Polygons tool, follow the steps in Table 42.

A-1

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 lone 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 (two-dimensional
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-of-way, 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. Either do not include
the area in the place at all (Scenario A in Figure 15), or include it in the place and flag it as a
corridor (Scenario C in Figure 15). Nevers include such areas within the place boundary without
flagging them as corridors (Scenario B in Figure 15).

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
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
U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

B-2

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 are
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 depicts a cadastral (parcel-based) boundary map and Figure 17 shows
how the boundary should be represented when it is sent to the Census Bureau.

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: GUPS

B-3

Figure 18. Place Boundary – Front-Lot-Line
Figure 18 - Shows a situation in which the place boundary is along the frontlot-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_2019_offset_.shp), so that the 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.

INTRODUCTION
A.

The Boundary and Annexation Survey

The U.S. Census Bureau (Census Bureau) conducts the Boundary and Annexation Survey (BAS)
annually 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, and Hawaiian Homelands. 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 BAS to tabulate data
for the decennial and economic censuses, and to support the yearly deliver of the American
Community Survey (ACS) data. Maintaining correct boundaries and boundary-to-feature
relationships through BAS helps ensure that the Census Bureau assigns the appropriate housing
and population counts to each governmental unit (GU).
In compliance with the Office of Management and Budget Circular A-16, 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, 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, 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 website at .
For more information on BAS, please view the “Introduction to BAS” video series on the Census
Bureau’s BAS website at .

What's New for the 2019 BAS?
1. The Census Bureau developed a BAS Partner Toolbox for ArcGIS users. This toolbox is designed
to simplify and standardize the BAS update process. See Appendix B for a step-by-step guide to
using this new tool.
2. The GUPS help videos previously embedded in the software are relocated to the BAS website.
3. Redistricting data contacts participating in the Voting District Project verification phase may
submit boundary updates for reconciliation with BAS contacts.
4. Website revisions.

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital viii

Key Dates for BAS Respondents

January 1—Boundary updates must be legally in effect on or before this date to be reported in
the current survey year.
March 1—Boundary updates returned by this date will be reflected in the ACS data estimates
and in next year’s BAS materials.
May 31—Boundary updates returned by this date will be reflected in next year’s BAS materials.

BAS State Agreements

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 until there is a documented final court decision regarding the
dispute. To learn more, 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.

Boundary and Annexation Survey Tribal Respondent Guide: Digital ix

SECTION 1: DIGITAL BAS REQUIREMENTS
1.1

Digital BAS Participation Requirements
1. 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).
2. All participants must provide current information for the tribal BAS point of contact, the person
updating the shapefiles, and the tribal chair.
3. 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 offreservation trust lands).
4. Each non-legal boundary correction must contain proper update documentation according to
boundary correction guidelines listed below in Section 1.3 Tribal Areas that can be
Submitted through BAS, or the Census Bureau will not make the correction for this BAS cycle.

1.2

All Participants Must Use SWIM to Submit Their Changes to the Census
Bureau

Due to security requirements, the Census Bureau cannot accept submissions via FTP, email or
any protocol other than the SWIM site. For details on registering and using SWIM, please see
Section 5.12.7 Submitting Digital Files via SWIM. To access SWIM, enter the following URL in a
new browser window: .

1.3

Tribal Areas that can be Submitted through BAS

The following can be updated through Tribal BAS:


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

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital 1



1.4

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.

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
website at: .
If there are any questions or concerns about the participation requirements, contact the Census
Bureau at 1-800-972-5651 or [email protected].
For participants already familiar with GIS and BAS updating procedures, Appendix B and
Appendix C provide step-by-step guidelines for making updates.

SECTION 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.

2.1

Topological Relationships in MAF/TIGER

At the Census Bureau, topology is described 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 Three Types of Boundaries
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.

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital 3

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, AIA boundary, and a school district boundary.

2.2

GIS and Spatial Accuracy

In a GIS, feature classes are often not topologically integrated; they are separated into
individual layers. When these layers are overlaid 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.

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital 4

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. Instructions are given in Section 5.6 Reviewing Changes to the
Census Bureau Shapefiles 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.
To find examples of suggested methods for correctly making boundary changes, please see
Appendix B.

2.3

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
to watch the video.

SECTION 3: CENSUS BUREAU PROVIDED SHAPEFILES
Please download shapefiles from the BAS website at:

in order to review the boundaries and submit changes.
The Census Bureau provides entity layers in ESRI shapefile format for download via the BAS
website. 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.
Note: Shapefiles are ‘county’ based so it is necessary to download all the counties in which the tribe has
reservation and/or ORLTs.

SECTION 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 (MSP)

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital 7

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 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.
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.

SECTION 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 Appendix B and Error! Reference source not found. 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.

Boundary Changes

In order to update MAF/TIGER, participants must create a separate change polygon layer for
each updated entity type (AIA, 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 addition, deletion, boundary
correction, new incorporation, geographic corridor, and geographic offset change polygons.
Review any boundary change polygons before submitting them (Section 5.12 Additional
Review Information).
If additional shapefiles are needed, please contact the Census Bureau at 1-800-972-5651 or
[email protected].

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital 9

5.3.1 Additions and Deletions
The Census Bureau will accept additions and deletions from AIAs 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 or Hawaiian Homeland) adding or deleting the area in the
NAME field.

5.3.2 Boundary Corrections
The Census Bureau will also accept specific boundary corrections from AIAs 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 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.
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 (addition,
deletion, corridor, offset) and meet both of the following two conditions:

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital 10




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

5.3.3.1 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).

5.3.3.2 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 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 the tribe.
Some examples of descriptors for tribal subdivisions are:
 District;
 Community;
 Area;
 Chapter;
 Segment;
 Administrative Area;
 Addition; and
 County District.

5.3.3.3 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 Error! Reference source not found. 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.
U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital 12

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 (shown in color)
created where the AIA owns the right-of-way but the housing units are not included within the
AIA. 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.

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
(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, 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.

The Census Bureau has included an “offset” shapefile in the BAS materials
(PVS_18_v2_offset_.shp), so that the 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 Update Guidelines
If a road, subdivision, etc. is missing from the Census Bureau’s feature network, add the
feature(s) and provide the name and MTFCC.
If a feature does not exist and is in the Census Bureau’s feature network, delete the feature.
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.

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 the
Census Bureau’s outgoing shapefiles, it is recommend that participants generally only add
address ranges to new features (see Table 8).

5.5.1

Area Landmark/Hydro Area Updates

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.
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.

Reviewing Changes to the Census Bureau Shapefiles

5.6.1

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.

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital 19

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.

Figure 13. Addition Created without Snapping to
Centerlines
This is an example of an addition 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 instructions 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 Spatial Correction Not
Incorporated
Small spatial boundary corrections would
dissolve the relationship with the river. These
boundary corrections will not be incorporated
into MAF/TIGER.

5.6.2

Figure 15. Small Spatial Correction Not Accepted
Small spatial boundary corrections would
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.

Large Boundary Corrections

The Census Bureau will not accept large boundary corrections to an entity without the
appropriate legal documentation (such as Trust Deed, Executive Order, new legal opinion, Act
of Congress or Federal Register Notice) and effective dates. These large boundary corrections
U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital 20

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.

5.6.3

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 Boundary
Changes for the required attribute information and corresponding change type codes.

5.6.4

Including Appropriate 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.

5.6.5

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.

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital 21

5.7

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 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.

5.7.1

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, it requires
documentation to update reservation and off-reservation trust land boundaries.
The following changes require documentation:







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 the tribe.

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital 22

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 the reservation
document.
If no documentation is available, please can contact the tribe’s 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.
For questions about documentation, please call the Census Bureau at
1-800-972-5651 or email [email protected]. To contact the BIA, please reach out to the
nearest regional office, see .

5.7.2

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:
1. Change Polygon Layers (AIA, Tribal Subdivisions, Hawaiian Homelands)
 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 (AIA, Tribal
Subdivisions, etc.) for which polygons are created.
2. Whole Modified Entity Layer (AIA, Tribal Subdivisions, and Hawaiian Homelands)
 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 for which polygons are
created.
3. Tribal Feature Network, Parcel and Boundary Layers (optional)
 These layers will help the Census Bureau resolve any questionable change polygons and
establish the correct boundary-to-feature relationships.
4. 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.
5. Area/Hydro Landmark Update Layer
 Only if there are area and/or hydro landmark updates.
6. Point Landmark Update Layer
 Only if there are point landmark updates.
7. BAS Contact Text File (if the BAS point of contact (the person that receives the BAS Annual
Response Email) has changed);
 This can be updated online at:

Compressing the Digital Files

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 the participant’s
updated BAS contact information).
Note: Centerline files or any additional information that may be helpful for Census to process the
participant’s 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.
1. Navigate to the directory with the shapefiles.
2. Select all files and right click on the selection.
3. 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 (e.g., 7zip) may be used to zip the return files.

Submitting Digital Files via SWIM

The Secure Web Incoming Module (SWIM) is a one-stop location for submitting 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 submissions as an email attachment, as the Census Bureau cannot accept them
due to security policy.
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.
This token is good for one personal account within the SWIM. Once participants have registered
for an account in SWIM, they will no longer need the token to login into the system. If
participants require additional individual SWIM accounts within their organization, please
contact the Census Bureau at 1-800-972-5651 or email [email protected].

2019 DIGITAL BAS EXAMPLE PROCESS 1

PARTNERSHIP TOOLBOX QUICK START

In an effort to ease the burden of BAS updating for the Census Bureau’s partners, the Census
GEO BAS team developed a Toolbox for ArcMap and ArcGIS. This plug-in facilitates the updating
process by automating the process of downloading data, creating changes, removing slivers,
formatting, attribute checking, and preparing/exporting files for submission.

B.2

TOOLS SETUP

B.3

RUN DATA DOWNLOAD

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital B-1

1. Expand the DBAS folder and the setup subfolder. In the setup folder find the
Partnership toolbox. Expand the toolbox and double click on 1) Census Data Download.

2. In the User’s BASID field, enter the BASID for the entity to be processed.

3. When this tool is complete, there should now be a folder for the BASID in the projects
folder. Inside that folder, there will be a geodatabase with reference data in it and an

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital B-2

archive folder.

Note: The archive folder contains other Census data that may be useful as well.

B.4

CREATE CHANGES

Once the necessary Census data is obtained, run the 2) Create Changes tool to make the change
polygons.
1. Double click on 2) Create Changes.

2. In the Create Changes window:
 In the Local Boundary File field, enter the path to full boundary polygon
 Enter the 11 digit BAS ID in the BAS ID field
 Under Changes Being Processed, choose the type of changes to create from the
dropdown options:
a) Incplace
b) County
c) Cousub (county subdivisions)
d) Aiaanh (Tribal areas)
 For the Name Field in local data, the boundary file may need to be modified to
match a field in the Census Bureau’s data. Type the name of the field (as it
U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital B-3

3. Once the tool is complete, the output will be placed in the geodatabase under the
submission feature dataset.

B.5

SLIVER BLASTER (OPTIONAL)

The Sliver Blaster is a useful tool for entities that have many very small change polygons that
are time consuming to manually parse through for deletion. Since the Census Bureau cannot
guarantee inclusion of changes under 30ft, use this tool to get rid of changes that are lower
than that threshold. Participants can also change the tolerance for the sliver blaster if they
know there are small changes that need to be included.

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital B-4

1. Double click on 3) Sliver Blaster.

2. In the Sliver Blaster window:
 The Changes File refers to the changes file created in the previous step, found in
the submission feature dataset.
 The Census Edges feature class is found in the benchmark feature dataset and is
called bas_edges
 The Buffer Distance is set to 30 feet by default, but this can be adjusted to
accommodate smaller changes

B.6

FORMAT WORKING MXD (OPTIONAL)

The intent of this tool is to create a map document (.mxd) for users containing their change file
and all of the other reference layers they will need to finalize a submission. If they would prefer
to use their own .mxd, this step is not required.

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital B-5

1. Double click on 4) Format Working MXD.

2. The only input for this tool is the Working Folder, which is the folder with the
participants’ BAS ID as its name.

3. Open the new .mxd and begin working with the change polygons.

B.7

ATTRIBUTE CHECK

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital B-6

1. Double click on 5) Attribute Check.

2. In the Attribute Check window:
 The Change File should be the change file created in tool 2) Create Changes for
which to generate a report
 In Geography Type choose the type of geography being worked on from the
dropdown. The same options as the Create Changes tool are available here
 The last input is the optional check box for Includes Changes in Georgia. This box
only needs to be checked if responding in the state of Georgia

3. There should now be a text file in the working folder called
attribute_check_ containing all discrepancies identified in the change file
that still need to be fixed.

U.S. Census Bureau

Boundary and Annexation Survey Tribal Respondent Guide: Digital B-7

B.8

EXPORT SUBMISSION

Upon review of the changes file and the attribute error report, the finalized changes can be
exported for submission to the Census Bureau. This tool can also be used to provided updated
contact information with the submission.
1. Double click on 6) Export Submission Files.

2. In the Export Submission Files window:
 Under Files to submit, add as many changes files as needed to update the
boundaries
 For BAS Contact, Entity Name, Contact Title or Department Name, Address,
Email, and Phone Number, please include any or all contact information updates
that are to be sent to the U.S. Census Bureau. These fields can be left blank if
there are no updates, though if someone other than the BAS contact prepared
the submission, they may want to include their information

2019 DIGITAL BAS EXAMPLE PROCESS 2

REQUIRED CENSUS BUREAU SHAPEFILES

When downloading shapefiles for the 2019 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_2019, 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 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 for all reservations and off-reservation trust
lands 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.

C.11 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. This process must be completed for each level of
geography (AIA, tribal subdivision) that has changes.

Note: See Section 5.7.6 Compressing the Digital Files 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
. For instructions on how to use SWIM, see Section 5.7.7
