In this segment, I'm going to talk about the types
of updates accepted through Digital BAS.
The Census Bureau accepts a variety of boundary updates.
The most common are Annexations, Deannexations
and Simple Boundary Corrections.
I will explain each in further detail later
in this presentation.
In addition to geographic areas, you may also provide updates
to linear features such as interstate highways
and local neighborhood roads.
Updates to address ranges, point landmarks, and area landmarks,
such as parks, cemeteries, and airports are accepted as well.
I will now discuss, in more detail,
the types of boundary updates accepted by the Census Bureau.
Annexations and Deannexations are legal changes.
Legal changes are those modified due to a legal action,
such as an Ordinance, Resolution, Court Order,
or recently Enacted Law.
Legal changes often result in large change polygons,
or change polygons that are not contiguous
with an existing boundary.
When creating change polygons for an annexation
or deannexation, you must provide the effective date
and document number of the ordinance, resolution,
or other legal document recording the change.
The Census Bureau will not accept legal changes
without this information.
For those entities in the State of Georgia,
you must also report the acreage
of an area being annexed or deannexed.
If you use the Census Bureau provided ESRI Shapefiles
and your own GIS to complete the Digital BAS, you are required
to provide data in the shapefiles' attribute table.
The name of the entity affected is required in the [NAME] field.
The effective date of any annexation
or deannexation is required in the effective date field along
with the authorization number in the document field.
All annexations require the letter A
in the change type field,
while deannexations require the letter D
in the change type field.
Entities in the State of Georgia are required
to submit the acreage associated with any annexation
or deannexation in the area field.
Boundary corrections are non-legal changes
and typically small spatial adjustments following the
general shape of an existing boundary.
The Census Bureau can accept boundary corrections
without any legal documentation as long
as the corrections do not cover a very large area.
If boundary corrections do cover a large area containing parcels
or buildings, it is likely
that the boundary correction is an unreported annexation
or deannexation that the Census Bureau does not have on file.
In these cases, please provide the authorization number
and effective date for any such changes.
If the Census Bureau has any questions for you pertaining
to large boundary corrections, we will contact you.
As with Annexations and Deannexations,
there are certain fields in the shapefiles' attribute table
that require information
when reporting non-legal boundary corrections.
The name of the affected entity should be provided
in the name field.
The letter B is to be included in the change type field
for all non-legal boundary corrections.
If you are submitting a boundary correction that will add area
to an existing boundary, you must add the word
IN to the relate field.
If you are submitting a boundary correction that will remove area
from an existing boundary, you must add the word
OUT to the relate field.
Data in the effective date and document fields are not required
for non-legal boundary corrections.
The Census Bureau accepts new incorporations via the
Digital BAS.
If you have any such changes to report,
the following information is required:
The name of the new incorporation, The name
and phone number of someone that the Census Bureau can use
as a point of contact, a copy
of the official papers supporting the incorporation,
the effective date of the new incorporation, a mailing address
for the new incorporation,
the name of the highest elected official
of the new incorporation, and the name of the BAS contact
of the new incorporation, if different
from the highest elected official.
In addition to boundary updates,
Linear Feature updates are accepted via the Digital BAS.
Digital BAS participants may add, delete, spatially adjust
or rename linear features.
However, street feature updates are optional unless the street
feature or features serve as a boundary for a geographic area.
As I previously mentioned,
all updates to the Census Bureau's geographic features are
recorded in the attribute table of your boundaries shapefile.
A data dictionary, which contains the definitions
of the attribute table fields and field properties,
is included in the Digital BAS respondent guide.
Once you complete your digital BAS updates, you will need
to compress the data files into a zip file.
After creating the zip file, you can upload the file
to the Census Bureau's Send a File Utility site.
If you use the MTPS,
the software will create the zip file for you.
Instructions on how to submit the BAS returns
to the Census Bureau via the Send a File Utility site are
provided in the Digital BAS respondent guides,
which are available on the BAS website
and on your data CD or DVD.
