- Abstract
- United States Urbanized Areas is a polygon theme representing urban areas in the United States derived from the urban areas layer of the Digital Chart of the World (DCW). This dataset is a part of the 2008 ESRI Data Maps collection.
- Purpose
- United States Urbanized Areas provides information about the locations, names, and populations of urbanized areas for conducting geographic analysis on national and large regional scales.
- Supplemental Information
- Largest scale when displaying the data: 1:1,500,000.

- Data Quality Information
- Logical Consistency Report
- The shapefile is converted to SDC (Smart Data Compression) format using either ESRI SDC Data Development Kit Professional 2 (DDKP2) or tools in ArcGIS. The SDC data set is then loaded into ArcSDE to verify and validate the geometry.
- Completeness Report
- After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
- Horizontal Positional Accuracy Report
- The geospatial part of this data set was originally extracted from the Digital Chart of the World at 1:1,000,000-scale with some geospatial data from a USGS 1:2,000,000-scale hydrography layer. It was updated several times using various sources whose horizontal positional accuracies are unknown.
