Description:

Abstract:: This data set is a polygon coverage representing the coal fields of the United States. Resolution of data is 1:5000000. Most of the material for the conterminous United States was collected from James Trumbull's "Coal Fields of the United States, Conterminous United States" (sheet 1, 1960) map. The gulf coast region was updated using generalized, coal-bearing geology obtained from state geologic maps. The Alaska coal fields 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 USCOKECOAL (point coverage of coking coal) and USAKCOALPT (point coverage of Alaska coal).
