Description
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, National Oceanic and
Atmospheric Administration National Ocean Service, and
data supplied by State Departments of Transportation.
The data sets were created and standardized by members
of the Geographic Information Systems Laboratory,
Pellissippi Research Institute, The University of
Tennessee, Knoxville.
DATA QUALITY INFORMATION
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.
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: 399 distinct Adjusted Urbanized
Areas (AUB) are identified database. Six (6)
Urbanized areas are enclosed within the boundaries of
other AUBs 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 Step
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.

Process Description: After completing topological and attribute
verification using ARC/INFO, the data was extracted and
reformatted into the BTS ACSII format, and converted into
shape file format and redundant fields were eliminated.
