Resolution of data is 1:5000000. The points were collected from Farrell Barnes's "Coal Fields of the United States, Alaska"(sheet 2, 1960) map. Updates are planned for the future. These updates will include the polygons used by energy resource regions of the U.S.G.S Energy Program in the National Coal Assessment. Data from Alaska will be incorporated using the most recent digital data available from Alaskan authorities. Purpose: This data set was compiled primarily for use in cartographic products. This coverage has also been used in web applications as well as in other miscellaneous graphic proudcts. Overall, the need for a digital version of this data was the underlying reason for generating this data set. Related covers include USCOAL (polygon coverage of US coal fields) and USCOKECOAL (point coverage of Alaska coal).

This command creates a point attribute table. Completeness_Report: This data set is a representation of the coal fields in Alaska of an undetermined extent. As such, they are represented as point features. The Barnes map was the only source of information ussed. Team scientists determined that this would provide the most up to date information concerning Alaskan coal fields of an "unknown" extent.
