I.
USING THE MTPS TO VERIFY AND CORRECT THE
VTD/BBSP SUBMISSIONS
This Attachment provides specific instructions on the installation and use of the MTPS
for verifying and submitting corrections to Voting Districts (VTDs), State Legislative
Districts (SLDs), Congressional Districts (CDs) and Block Boundary Suggestions
(BBSP) to the Census Bureau.
Note: If not experienced with using the MTPS, it is critical to read this document in its
entirety, as the sections build upon each other and each step is important.
In February 2010, the Census Bureau delivers verification products to the state
participants for the VTD/BBSP. The verification products comprise the MTPS (Version
5.5) 1 and the Census Bureau provided shapefiles that reflect the processed and completed
updates inserted into the MTDB. In some cases they reflect changes already discussed
with the state and RCC staff. The Census Bureau delivers the VTD/BBSP verification
products on Digital Versatile Disk (DVD) to the participating states.
Depending on the computer and equipment, and the size of the state, installation of the
MTPS and the data can take up to 45 minutes.
The state data may be loaded into more than one computer or a local network server.
However, make sure that only one person is working on a county (or county equivalent)
at a time. Multiple data sets cannot be merged for the same county.
Also, since the MTPS is built on Maptitude it prevents more than one Maptitude session
from running at the same time. If a Maptitude session is open, close it before opening the
MTPS.
A. MTPS Installation
If the MTPS has not been previously installed, follow these steps:
1.
Start .
2.
Insert the Program DVD, the MAF/TIGER Partnership Software 2009, Version
5.5 into the DVD drive.
3.
If the Installation Wizard does not automatically start up, choose the Run
command from the Start menu.
4.
Type the location of the DVD drive plus the word “setup” (for example, type
d:\setup), or use the Browse button to locate the setup.exe file on the DVD.

VTD/BBSP Help
Review the on-line help for the VTD/BBSP program by choosing from the top menu,
Help Contents MTPS Census Programs Help VTD/BBSP. The Help menu
also provides instructions for various other topics. For instance, under Basic Skills learn
how to create layouts to use in documents or reports. This also provides information on
how to preview and make changes to a layout, edit and replace maps and dataviews, and
print a layout. The Help menu also includes an Index tab at the top to search a topic.
Note: To learn more about a command, dialog box, or toolbox, open or highlight the
item and press F1 to get the appropriate topic in the on-line help. To review the
function of an icon on any toolbox, hover the cursor over the icon and a text box
will appear describing the function.
C. Starting the MTPS and Selecting a County to Verify
Before opening the RDP.map window, a county (or county equivalent) must be picked to
verify. The MTPS then imports the data for that county. The MTPS is designed to work
on one county at a time. Each time the RDP.map map window is opened, it displays the
last county that was edited. To verify a different county, close the RDP.map window,
pick another county, and open the VTD/BBSP map window again.
To pick a County (or county equivalent) to verify, follow these steps:
1.
Choose from the menu bar at the top, VTD/BBSP Pick a County. The MTPS
displays the MTPS Counties dialog box.
2.
Highlight a county in the scroll list.
3.
Click OK.

to see the map layers and their settings, as follows:
Turn map layers on or off depending on what to display on the map. For example, if
VTDs have nothing in common with school districts, there is no need to display them and
thus turn that layer off (Hide Layer). If reviewing SLDs or CDs to ensure that any
relationships with other governmental entities are intact, turn those respective layers on
(Show Layer).
Note: The first item listed in the Layers in Order of Display column, VTD, is the first
layer drawn on the map. The remaining layers are drawn sequentially, with each
added layer being drawn on top of the previous one.

district) the label is attached to the edge nearest to the center point. The labels are
static when zooming in or out and panning.
The labeling engine makes a determination of which labels to draw and which to
suppress when the drawing of all the labels would cause them to overlap. If it is
zoomed into where the individual blocks are being labeled, this suppresses the
VTD labels in some areas where drawing them forces an overlapping label. To
see the VTD labels only, turn off the block labels. As long as no other area or
feature labels overlap, the VTD labels should then appear.
G. Reviewing the VTD/BBSP Submission
For reviewing VTDs, select Voting District as the Edit Layer. For reviewing other
RDP entities, select SLD Lower, SLD Upper, or Congressional District in the Edit
Layer for reviewing these RDP districts.
This section focuses on the review of the VTDs. Review and verify the VTD Code,
Name, and the boundaries.
Note: Turn off or hide the water layer in the Map layers dialog box when viewing VTD
coverage because that layer appears on top of the VTD layer, making it difficult
to view the VTD coverage.
Note: Hover cursor over any area to identify the VTD. A text box appears with the
VTD Name.

appears.
and click an area. The Dataview1 –VTD Info
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission
14
Verify that the following elements are correct:
Verify that the VTD codes (ranging from 1-6 alphanumeric characters) are
correct. The Code may include dashes, dots, or forward slashes.
Verify that the VTD names are correct. If a Name is not provided in the
submission, the Census Bureau uses the VTD Code as the Name.
Note: Names can be up to 100 characters, including alphanumeric, spaces
(consecutive spaces not allowed) and all special characters. If a VTD
Name uses all 100 characters, the Census Bureau does not add the words
“Voting District” after the name. Adding the “Voting District” character
string is too long in these cases. This is accomplished by assigning a
Legal Statistical Area Description (LSAD) code of “00”. (See a full
description of the LSADS on an upcoming page.) Codes and names
should be consistent and should be reviewed for spelling accuracy,
keeping in mind that these names will appear in public products.
Note: If any area was submitted with unassigned areas (uncoded faces 4 ), the
Census Bureau assigns the code of ZZZZZZ to these unassigned areas.
These are identified as Voting Districts not defined which appear in the
American FactFinder and the P.L. summary files. This ensures that the
Census Bureau has accounted for all faces in the county.
4
Faces is the MTPS term for polygon.
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission
15
Verify that the VTD boundary is correct and where relevant, is following the
correct visible or non-visible feature. These features may be geographic entity
boundaries such as township and incorporated place boundaries, or visible
features such as roads or water features.
Note: If a VTD follows a township or incorporated place limit that has moved,
adjust the VTD to the new township or corporate limit. The Census
Bureau only maintains whole entity relationships as described in the
Relationship Information Review document.
Note: At any time during the review and verification, a list can be reviewed of
all submitted VTDs. With the VTD Editing toolbox open, generate this
VTD inventory file for all current VTD codes and associated names by
selecting VTD from the dropdown menu on the Standard toolbar.
Then click the New Dataview icon
. The Dataview2 – VTD table appears.
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission
16
Note the VTDI and LSAD fields in the Dataview table:
VTD1: This stands for Voting District Indicator. A = Actual; P =
Pseudo.
An A = Actual VTD is one that exactly matches the VTD (election
precinct, ward or other election area) boundary in the state. If the VTD
does not reflect the actual election VTD boundaries, the state may
designate P = Pseudo.
Note: If the state does not designate the VTD1, the Census Bureau
designates P = Pseudo for the requisite VTD.
LSAD: This stands for Legal Statistical Area Description. These codes
determine the way the names of some entities appear in products.
V1 = “Voting District” is the prefix to the VTD Name. For example,
if VTD Name is “5”, the NAMELSAD = Voting District 5.
V2 = "Voting District" is the suffix to the VTD Name. For example,
if VTD Name = “Albemarle”, the NAMELSAD = Albemarle
Voting District.
00 = no prefix or suffix to the VTD Name. For example, if VTD
Name is “Queen Anne’s Precinct 01-001”, the NAMELSAD =
Queen Anne’s Precinct 01-001.

H. The VTD Editing Toolbox
All VTD editing and corrections required for boundaries and line work are performed
using the VTD Editing toolbox. The dropdown selections in the VTD Editing toolbox
are:
Edit Layer: The layer to edit (the layer to correct or update; Voting District,
SLD Lower, SLD Upper, or Congressional District)
Target Area: The area to edit, either editing a New District, a submitted
district, or Unassigned area. For verification, typically an
district is corrected. Selecting New District is for adding a new VTD.
Source Area: The areas from which to select, either editing All areas, an
district, or Unassigned area. Typically All is selected for the Source
Area. Selecting an area for the Source Area restricts the designated
Target Area to only those faces in the selected Source Area.
Selection Layer: Faces, or a specific geographic entity. The layer from which
to select. Typically select Faces. If the VTD is coextensive with a specific
incorporated place or (other geographic entity), select Incorporated Place and
place the cursor in the respective incorporated place to add this area to the Target
Area VTD).
Note: There should not be any Unassigned VTD area (faces) in verifying the
submission. The submission is checked and validated for any area(s) not assigned
to a VTD. The RCC may have consulted the state participant regarding any
unassigned faces for a VTD and solicited guidance on what the VTD assignment
should be. Ultimately, for areas that were not assigned a VTD code, the Census
Bureau enters the ZZZZZZ code as previously mentioned.
Follow these steps for editing and correcting a VTD using the VTD Editing toolbox.
1.
Choose a layer from the Edit Layer dropdown list in the VTD Editing toolbox.
Selections are Voting District for correcting or viewing submitted VTDs, SLD
Lower (SLDL), SLD Upper (SLDU), or Congressional District.

Correcting VTDs Using a Layer From a Local Database as the
Source
Some states maintain a VTD layer in their own Geographic Information System (GIS)
software. The MTPS allows participants to import these files (some of which are
compiled from the Census Bureau supplied data shapefiles) and use them to review and

symbology that is conducive to seeing the local VTD boundaries superimposed on
the file. A Border Style with a dashed symbology, Border Color of red, and
Border Width of 1.5 is one suggestion.
12.
Set the labels to identify the VTDs by clicking on Labels. Scroll to Precinct on the
Field drop down menu; on the Position drop down menu select Centered; select
the Arial Font at Size 16 Bold is one suggestion.
13.
Click Apply.
Note: When adding an external file (a local GIS file, table, or imagery) to the MTPS
project, it is essential not to move the file from the location from which it was
added. To do so will cause the application to not open since it is not able to find
the added file and “crashes”.
Therefore, it is important to either remove the added local file from the layers
before closing the application or be certain to not move the file's location and be
sure to have any needed network connections to the file's location when relaunching the application.
J.
Using a Block Equivalency File (BEF)
The MTPS has a function to create VTDs from a BEF. For verifying VTDs, the
Census Bureau does not recommend using this function as it will likely result in
more work.
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission
25
The following sections in regards to the BEF are more for information purposes only.
Only use this approach if VTDs are maintained using Census tabulation blocks. If using
this process, more accuracy is achieved when using the most current Census blocks to
compile the BEF. As the MTDB is updated with new legal boundaries (for example,
incorporated place limits) or with new streets and roads, the Census 2000 tabulation
blocks are divided into smaller blocks through a process called “block suffixing.” For
example, a Census 2000 tabulation block number of 1004 may now be divided into
smaller blocks that are numbered 1004a, 1004b, and 1004c. These “current” blocks have
been provided in public TIGER/Line products over the years. If the block in the file is
“1004,” and does not contain the current suffixes, the MTPS does not associate a VTD
code to the suffixed blocks. Find and fix these areas during a VTD editing session using
the MTPS, as described in Section I.H. The VTD Editing Toolbox.
To correct VTDs with a BEF that is maintained in the local GIS or database application,
select Import Equivalency from the Area Settings: Voting District box, when opening
the county of the VTDs to correct.
Click OK.
The Choose File to Import box appears: (The MTPS only supports the following file
types: .bin, .txt, .csv, .dbf, .asc.)
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission
26
Choose a file and click Open. MTPS displays the Import Block Equivalency File
dialog box. Choose the field from the BEF which matches the block field from the
Match Block Field To dropdown list and the field which contains the district code from
the Fill District From dropdown list, then, click OK. Each field in the state's block
equivalency file should have a descriptive name such as BLOCKID and DISTRICT.
This makes it easier to identify and select the Match Block Field To and Fill District
From fields when using the importer. If the fields are not given a name, the first record
in each field appears in the drop down lists as the field names.
Block Equivalency File Format
In order for the match to work, the state BEF must contain two fields in each record. The
first field (named BLOCKID in the graphic below) contains concatenated state, county,
tract and block codes. If using current blocks there may be an additional block suffix
appended at the end of the block code (as appears in the SUFFIX1 column below). For
example, BLOCKID appears as 110010001001001, where the 11 is the state FIPS code
(STATEFP in the example below), 001 is the county FIPS code (COUNTYFP below),
000100 is the TRACT number and 1001 is the BLOCK number. If the block is suffixed,
the BLOCKID appears as 110010001001001A, containing the additional A, as shown in
the SUFFIX1 column below. If the BEF currently shows those geographic areas as
separate fields, concatenate them into a single field before performing the import. The
second field is the VTD_CODE.
In the example below the BLOCKID field is used in the Match Block Field To pull
down menu. The VTD_CODE is used in the Fill District From pull-down menu.
Once the import is completed, the MTPS fills the county based on the VTD codes
included in the local file. However, as mentioned before, if the block record in the local
file does not contain the current suffixes (if that block has been suffixed), that block does
not fill with a VTD code.
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission
27
Each VTD appears highlighted in a different color to distinguish adjacent VTDs.
1.
Find and fix any unassigned or non-contiguous areas using an editing session as
described in Section I.H. The VTD Editing Toolbox.
2.
Review the boundaries of these VTDs. This is a very important step. Make sure
that each VTD is following the correct feature. The Census Bureau’s MTDB has
changed significantly since Census 2000 and this can affect the feature to VTD
relationship.

Click
correct the Code, Name, Relationships, or the Pseudo (VTDI) assignment. Note
that the existing VTD must be selected in the Target Area dropdown menu of the
VTD Editing toolbox.
4.
To correct (or create) a VTD using these VTDs as a starting point (for example,
create two “new” VTDs from one existing VTD), select New District in the Target
Area dropdown menu.
K. Reviewing and Correcting BBSP Submissions
As part of the VTD/BBSP verification, review each county (or county equivalent) for the
correct flagging on features to hold (Must Hold) as 2010 Census tabulation block
boundaries or linear features to not hold (Do Not Hold) as block boundaries as being
correct.
Note: All Must Hold block boundary suggestions are contingent upon the lines
intersecting to form a closed polygon at the time the Census Bureau creates the
2010 Census tabulation blocks, which occurs in the fall of 2010. For this reason
all block boundary suggestions must form a closed polygon with other planned
block boundaries.
Note: If any other program sponsored by the Census Bureau flags a line as a Do Not
Hold as a block boundary, on a BBSP Must Hold, the Census Bureau overrides
the (other program) Do Not Hold status of the line.
Review and verify that any Block Area Groups (BAG) are correct.
L.
Planned 2010 Census Tabulation Block Boundaries
The list below specifies the entity boundary description and the MAF/TIGER Feature
Classification Code (MTFCC) that are currently planned as 2010 Census tabulation block
boundaries.
It is not necessary to suggest any MTFCC on this list as a Must Hold.
Note: It is not allowed to suggest any of these MTFCCs as a Do Not Hold.

If trying to add a Do Not Hold suggestion for a line feature marked as a Planned
Hold, the MTPS displays a Note:
Click OK.
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission
34
Note: Remember that the boundary of each governmental entity (or statistical
entity) 5 is held as a 2010 Census tabulation block boundary as are most
roads. Private roads, trails, and unimproved roads may or may not be held
and therefore are more eligible for a Do Not Hold suggestion.
R. Feature Extensions
To form a closed polygon, a short line feature extension may be added. Requirements for
feature extensions are:
no longer than 300 feet;
straight lines from the end of a road and intersecting a non-road feature. These
include all hydrographic features, pipelines, powerlines, and railroads. Highways
and freeways are acceptable as long as it is confirmed that there are no housing
units on them. This situation has the potential for causing a housing unit to be in
the wrong Census 2010 tabulation block.;
not intersecting a cul-de-sac.
Verify that the submitted (approved) feature extensions are correct.
To create a new feature extension, add the line as described in Section II.E. To Add a
Line.
S.
Dividing Large Water Blocks
If during verification it is necessary to add a line to divide large water blocks for the
BBSP program, add the line and assign an MTFCC of P0002. Also assign a Must Hold
status to the line.
T.
To Verify any BBSP Flagging, Unassigned, and Non-Contiguous
VTDs
1.

corrections are valid.
When all tests pass, the MTPS displays the message; The verification of
VTD/BBSP data was successful.
Click OK to close the message.
II. ADDING ANY LINES AND PROVIDING IMAGERY
As mentioned in the VTD/BBSP Verification Guidelines for Participants, features added
as part of the Census Bureau’s Address Canvassing Operation, which was held in the
spring/summer of 2009 are reflected in the VTD/BBSP verification products.
In verifying the Phase 2, VTD/BBSP file, if a road feature (and only a road feature) is
identified as still missing and not included in the MTDB as reflected in the verification
materials, it can be submitted to the Census Bureau to add.
Recent imagery and/or links must be provided to substantiate the road add(s). If
imagery is not provided, the Census Bureau examines all viable imagery, source,
and reference material in determining if the road candidate is added. The Census
Bureau accepts road adds and updates upon validation with requisite imagery and
source material.
The following source material may be accepted:
add imagery from TerraServer USA
include own imagery
mail or fax an image or map
provide a URL to display an image or map
Add any non-visible VTD (and other RDP boundaries, i.e., SLDU and SLDL) boundaries
for correction and label them as such.
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission
36
See Section II.E. for instructions on adding a line.
A. Importing Digital Imagery from TerraServer USA
Microsoft Corporation maintains TerraServer USA, an on-line database of high
resolution United States Geological Survey (USGS) aerial imagery and scanned USGS
topographic maps. This can be used to submit requisite imagery for the line add(s) and to
add as a new layer in the MTPS map.
The .NET Framework must be installed to use this command; for more information, see

Toolbox. Click
to retrieve the image.
To save an image to be included in verification corrections and update, click Save and
choose Jpeg in the Files of Type dropdown menu, in the Save As dialog box. Be certain
to include the state and county FIPS codes as part of the name.
To learn more about adding imagery, see the Using Images in a Map lesson in the CBT.
Also, when activating the TerraServer-USA Image Tool toolbox, press F1 to be
directed to the on-line help documentation for that toolbox.
B.
Adding Digital Imagery as a Layer
If any recent state or local digital imagery is available, this imagery can be added to assist
in the verification review. To add any state or local digital imagery as a layer, use the
Add a Layer function as described on page 13. The imagery must be in a geo-referenced
format to export the image into a format that can be read by the MTPS. These can be
seen by using the Add a Layer function and then using the File Type pull down menu.
Be sure to include the state and county FIPS code as part of the name.
C. Mailing or Faxing an Image or Map
To provide an image or a map to show that a feature does or does not exist, mail or fax it
to the respective RCC office.
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission
37
Be certain to clearly reference the image or map (i.e., image or map #) 6 with the specific
large scale location of the line add in the specific state and county (or county equivalent).
Include a contact person and e-mail and/or telephone number in reference to the image or
map. The RCC may be in contact if there questions regarding the line add.
To provide information for a deleted line, the image or map must clearly show that a line
no longer exists. When selecting the line for deletion, provide an explanation in the Add
a Comment box that appears and reference the image or map that has been mailed or
faxed to the respective RCC.
D. Providing a URL to Display an Image or Map
To supply a URL to display an image or map, include the URL, state and county (or
county equivalent) and FIPS code and e-mail it to the respective RCC. Be clear to
reference the state and county (or county equivalent) and the location of the specific line
being added.
When providing URLs to existing imagery, provide the full path to the specific imagery
that contains a close up of the feature or area being revised or added. The Census Bureau
requests this to increase the likelihood to accept the changes and corrections identified by
the participant for verification. Be certain to clearly reference this link with the large
scale location of the line add in the specific state and county. Include a contact person
and e-mail and/or telephone number in reference to the image or map. The RCC may be
in contact if there are questions regarding the line add.
After requisite imagery, map and/or other source material is provided, the line can be
added during the verification process.
E.
To Add a Line
To engage the Line Editing tool, select VTD/BBSP Line Editing Toolbox.
The Line Editing tool appears.
Any line added too close to existing lines may not be accepted. To avoid this problem it
is highly suggested to use existing lines, if possible, when delineating VTD (or other
RDP) boundary lines. If an added line repeatedly intersects or is within 10 meters of
another line, the MTPS prompts to use the (close) existing line.
6
This is more paramount when submitting multiple images and/or maps.
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission
38
The line numbers in the above Confirm box are called line IDs. If the line has no name,
only the line ID is listed. To review the referenced line, follow these steps:
Make a note of the numbers in the box.
Click Yes. (The line just delineated is not added to the map)
Make sure that All lines appears in the drop down menu on the Standard toolbar
at the top.
Click on the Dataview Icon
Click on Edit in the Standard menu at the top.
Click Find.
Type in the number in the Dataview Find box.
Click OK.
Right click on the Record ID.
Select Zoom.
MTPS zooms to the line. Hover the cursor over the line, a box appears with the line ID
number.
If a line is within 15 feet of a Census provided line, do not add it. Lines added within 15
feet of an existing line are not added (inserted) during the verification phase of the
VTD/BBSP.
The steps for adding a line for VTD/BBSP correction are as follows:

to activate the Add Line tool.
Note: When digitizing shapepoints, if the line intersects any existing line, enter a
shape point (left-click) precisely at the point of intersection. This precludes
a segment from snapping to other existing nodes (vertices) when digitizing
completes.
5.
Be sure to zoom in sufficiently to see that the end point is connected to another line
to form a closed polygon.
Note: To end the digitizing of a line without actually creating the line started, hit
the Esc key.
6.
To finish the line, double-click to end it. (Click at a node [either at an intersection
or at the endpoint of a line], on a line, or in space.)
The MTPS adds the new line and displays the All Lines – Editing Attributes
dataview box.
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission
40
If the line is too close to, or intersects another line, the MTPS displays the Confirm
dialog box.
Follow the instructions above to review the suggested lines.
If it is not desired to use an existing line, see the following note.
Note: For adding lines in tight topology, lower the snapping distance. Choose
from the top menu, Edit Preferences. On the System tab, change Snap
Tolerance to the distance and units desired. 10 feet is one suggestion.

Click OK.
7.
After changing the snap tolerance, re-add the line. After double clicking the end
point of the added line, the Confirm box appears.
Click No to use the added line.
8.
Now the Dataview1 – All lines – Editing attributes panel appears. Specify the
MTFCC for the line add. Do this by double-clicking the panel to the right of
MTFCC and select a feature type from the dropdown list. See the following
example of assigning a Local Neighborhood Road.
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission

9.
If adding a correction line to be a non-visible VTD boundary, choose P0001
(Non-visible Legal/Statistical Boundary).
If adding a correction line to be a feature extension, choose P0004 (Other
non-visible bounding Edge (e.g., Census water boundary, boundary of an
areal feature). See Section I.R. Feature Extensions.
Click the icon to the right of FULLNAME to enter any name. See the following
example.
If the feature added does not have a name, describe the line being added in the
FULLNAME field as follows:

Click
to add the line or
to cancel the added line. Also go to Edit Undo,
while still in the map window, to cancel any added saved lines.
Note: The Line Editing tool allows users to delete, split, and copy lines; edit line
attributes; and display names and address ranges. A deleted line that has been
added and saved appears as a red dashed line. For more information on this
toolbox, review the Editing Linear Features lesson in the CBT. Also, highlight
the tool and press F1.
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission
43
Note: Many pre-existing line attributes, such as addresses, are not editable in the RDP
version of the MTPS. Furthermore, in regards to address ranges, when a line is
split in the MTPS, both segments retain the original address range. The address
range “imputes” the range break in the MTDB.
III. IF STATE/LOCAL GEOGRAPHIC DATA IS NOT
CONSISTENT WITH CENSUS BUREAU DATA
Since the geographical data displayed in the local layer may not align exactly to the
Census Bureau MTDB file, it may be necessary to adjudicate this geography. For
example, if a VTD follows a school district boundary and the location of the school
district is different between the local file and the Census Bureau MTDB file, use the
school district boundary as aligned in the MTDB location. This situation is demonstrated
in the graphic below. If local knowledge determines that the school district boundary (or
other geographic entity boundary) is incorrect or is out-of-date, contact the Geography
Division by sending an email to [email protected]. Census Bureau staff
will provide the appropriate contact person, for school districts this would be the mapping
coordinator. If the boundary requires correction, work with the school district mapping
coordinator to correct the Census school district boundaries, and if agreed upon, the
change will be reflected in a later Census Bureau shapefile product.
To ensure that the VTD and the school district (or any other legal or administrative area)
boundary maintain that relationship, provide relationship information as instructed in the
Relationship Information Review document.
Census Bureau and local school district boundaries have a similar shape but are in
different locations.
Instructions for Using the MTPS for Verifying the VTD/BBSP Submission
44
A. Boundary Corrections/Kinks and Distortions
The Census Bureau files sent out with the initial VTD/BBSP may have contained state,
county, and other boundary types with “kinks” and boundary distortions.
The Census Bureau has been working to correct these situations. This boundary review
and repair work will continue up until the Census Bureau creates the 2010 tabulation
blocks in the fall of 2010. Some of these distortions have been repaired in time for the
VTD/BBSP verification. In some cases, the Census Bureau has opted to “keep” the
distortion if re-alignment and coordinate enhancement actually causes the roads and
potential housing units to “move” from one governmental unit to another. In order for
the Census Bureau to enter that type of correction, confirmation from the BAS
respondent is required.
B.
Boundary Corrections for Legal State, County, Minor Civil
Division (MCD), and Incorporated Place
The initial phase of the VTD/BBSP work highlighted many areas of the country where
local officials have not provided responses to the BAS. For this reason, the Census
Bureau’s legal boundary may be out of date. Many RDP liaisons have worked within
their states to raise awareness of the importance of the BAS and the Census Bureau has
acknowledged a good response to the 2009 BAS. The VTD/BBSP verification files to
review reflect the results of the 2009 BAS. The Census Bureau conducts the 2010 BAS
in November, 2009 – March, 2010. Any additions or boundary updates to legally defined
areas must be submitted to the Census Bureau as part of the 2010 BAS in order to be
reflected in the 2010 Census.
For information about the 2010 BAS, go to:
http://www.census.gov/geo/www/bas/bashome.html
Refer any questions or for further information, e-mail the BAS team at
[email protected]. Please include the complete name of the legal entity in question, a
contact person, phone number and if possible an e-mail address.
IV. VALIDATING ANY CORRECTED VTD/BBSP
To ensure that any and all VTD/BBSP corrections and updates are complete and valid,
execute the built-in edits in the MTPS before submitting these corrections and updates to
the Census Bureau. These edits comprise identifying any unassigned areas and
noncontiguous areas.
Note: It is suggested to execute these validations even if not entering and submitting any
corrections or updates to ensure there were no inadvertent changes to the file
