This is a revised version of the 1998 data set. Only minor corrections have been made. Purpose: These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the U.S. Geological Survey in the use of these data.

Positional_Accuracy: Horizontal_Positional_Accuracy: 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.

Where the urban boundaries extended beyond the shoreline of ATLAS-STATES, the shoreline was matched to the ATLAS-STATES shoreline. Names of the urban areas were added using names in ATLAS-CITIES98. In large metropolitan areas many smaller areas were labeled as part of the metropolitan area. The State in which the urban area is located was also added. Several areas were modified to conform to the 1:2,000,000-scale hydrography (ATLAS-HY) layer. Some smaller polygons that represent undeveloped areas within the urban area were removed and merged with the larger urban area. Military reservations were also removed. Finally, the attribute for State FIPS was added.
