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 Date:  19940901

    Source Produced Citation Abbreviation:  FA_UZA

 

  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.
