Description:

Abstract:

This dataset provides the boundaries of census defined urbanized areas (scale: 1:24,000). A separate ARC/INFO polygon exists for each urbanized area.

For distribution with BASINS v.2.0, the data layer was prepared in Arcview shape file format.

Purpose:

This dataset was created to show the location and extent of urbanized areas in the United States. This type of coverage is useful in determining areas which may have high population densities, significant water quality monitoring information, and significant discharges.

Supplemental_Information:

Intended use of data: This data set was prepared to support the U.S. EPA BASINS (Better Assessment Science Integrating Point and Nonpoint Sources) System.

Process_Step:

Process_Description:

The source data were extracted originally from the U.S. Bureau of the Census' UA Limit File. The data were then processed into ARC/INFO polygon coverages. A separate ARC/INFO polygon coverage was created for each urbanized area. These coverages were then merged for each U.S. EPA Region and used to create a line coverage and point coverage for each region. The line coverage contains the Urbanized Area boundary line work, and the point coverage contain a point within each UA boundary. Associated with each point are the appropriate UA name and UA code. As part of the quality assurance of the enhanced data, the relative shape and location of each Urbanized Area boundary was compared against the Rand McNally Road Atlas. The UA name and code attributes were checked against the UA Limit File documentation for correctness. The UA points were also checked to make sure there was only one UA name per UA boundary.

Process_Date: 19960500

Process_Step:

Process_Description:

For distribution with BASINS v2.0, the ARC/INFO coverages in BASINS v1.0 that included the spatial extent of each of the ten U.S. EPA Regions, plus the 8-digit hydrologic units that crossed region boundaries were reprojected from Albers to Geographic projection and converted to ARCVIEW shapefiles.
