- Abstract:
-
The Federal Aid Urbanized Area Boundaries database is a geographic database of Federal-aid boundaries for urban areas with a population greater than 50,000. The database includes boundaries for urban areas in all 50 states, the District of Columbia, and Puerto Rico.
- Purpose:
-
The data provide users with information about the locations, names, urban, census and FIPS codes, and size of urban areas primarily for national planning applications.

- Data_Set_Credit:
-
The Federal-Aid Urbanized Area Boundaries files were compiled from a variety of sources including the US Bureau of the Census (BOC), National Oceanic and Atmospheric Administration (NOAA) National Ocean Service (NOS), and data supplied by State Departments of Transportation (DOTs). The data sets were created and standardized by members of the Geographic Information Systems Laboratory, Pellissippi Research Institute, The University of Tennessee, Knoxville.

-
- Attribute_Accuracy:
-
- Attribute_Accuracy_Report:
-
Attributes for the Adjusted Urbanized Area database are created in a consistent manner with a similar tolerance. Other attributes in the Adjusted Urbanized Area database were taken from the Highway Performance Monitoring System Field Manual Appendix B. All area and distance calculations are calculated to the nearest 50m.
- Quantitative_Attribute_Accuracy_Assessment:
-
- Attribute_Accuracy_Value: unknown
- Logical_Consistency_Report:
-
All node-link and polygon topological relationships are created and verified using computer algorithms. Uniqueness of entity IDs are similarly verified by computer algorithm.
- Completeness_Report:
-
A total of 399 distinct Adjusted Urbanized Areas (AUB) are identified in the database. Six (6) Urbanized areas are enclosed within the boundaries of other Adjusted Urbanized Areas and are not defined.
- Positional_Accuracy:
-
- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:
-
The positional accuracy of each data set varies as described. The Adjusted Urbanized Area database was created from data which had scale of 1:100,000 or better and as such has a positional accuracy of +/- 80m. The shorelines for the 23 coastal states were created using 1:250,000 NOS digital data which has a positional accuracy of +/- 200m. Thus, all internal political boundaries have a higher accuracy than do the coastal definitions with the exception of Alaska.

- Process_Description:
-
All state supplied maps were digitized using ARC/INFO V6.1x. All State supplied digital data was converted to ARC/INFO using a variety of encoding methods. The state databases were appended and adjusted to correct minor geodetic problems. After attributes were added and the data set checked for completeness and accuracy it was extracted from ARC/INFO and reformatted into ASCII data files. After completing topological and attribute verification using ARC/INFO, the data was extracted reformatted into the BTS ASCII format, and converted into shapefile format and redundant fields were eliminated.
