Summary

VA_TOWN is a feature class representing town boundaries in the Commonwealth of Virginia. This dataset was derived from Census TIGER data supplemented with locality data made available from the towns involved or the counties containing the towns.

Description

The VA_TOWN dataset is a feature class component of the Virginia Administrative Boundaries dataset from the Virginia Geographic Information Network (VGIN). VA_TOWN represents the best available town boundary information to VGIN.

VGIN initially sought to develop an improved locality and town boundary dataset in late 2013, spurred by response of the Virginia Administrative Boundaries Workgroup community. The feature class initially started from an extraction of town features from the Census TIGER dataset for Virginia. VGIN solicited input from localities in Virginia through the Road Centerlines data submission process as well as through public forums such as the Virginia Administrative Boundaries Workgroup and VGIN listservs. Data received were analyzed and incorporated into the VA_TOWN feature class where locality data were a superior representation of town boundaries.

Use limitations

The VA_TOWN feature class is not an official boundary description and shall not be used as one. Best efforts were undertaken to ensure the correctness of Administrative Boundary data by using the best source available throughout the Commonwealth of Virginia, however, all warranties regarding the accuracy of the map data and any representation or inferences derived there from are hereby expressly disclaimed.

Data Quality 

Attribute Accuracy
Attribute Accuracy Report
Accurate against Federal Information Processing Series (FIPS), FIPS Publication 6-4, and FIPS-55 at the 100% level for the codes and base names.  The remaining attribute information has been examined but has not been fully tested for accuracy.
Logical Consistency Report
The Census Bureau performed automated tests to ensure logical consistency and limits of shapefiles.  Segments making up the outer and inner boundaries of a polygon tie end-to-end to completely enclose the area.  All polygons are tested for closure.
The Census Bureau uses its internally developed geographic update system to enhance and modify spatial and attribute data in the Census MAF/TIGER database.  Standard geographic codes, such as FIPS codes for states, counties, municipalities, county subdivisions, places, American Indian/Alaska Native/Native Hawaiian areas, and congressional districts are used when encoding spatial entities.  The Census Bureau performed spatial data tests for logical consistency of the codes during the compilation of the original Census MAF/TIGER database files.  Most of the codes for geographic entities except states, counties, urban areas, Core Based Statistical Areas (CBSAs), American Indian Areas (AIAs), and congressional districts were provided to the Census Bureau by the USGS, the agency responsible for maintaining FIPS 55.  Feature attribute information has been examined but has not been fully tested for consistency.
For the TIGER/Line Shapefiles, the Point and Vector Object Count for the G-polygon SDTS Point and Vector Object Type reflects the number of records in the shapefile attribute table.  For multi-polygon features, only one attribute record exists for each multi-polygon rather than one attribute record per individual G-polygon component of the multi-polygon feature.  TIGER/Line Shapefile multi-polygons are an exception to the G-polygon object type classification.  Therefore, when multi-polygons exist in a shapefile, the object count will be less than the actual number of G-polygons.
Completeness Report
Data completeness of the TIGER/Line Shapefiles reflects the contents of the Census MAF/TIGER database at the time the TIGER/Line Shapefiles were created.
