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).

Other images are also available. Browse_Graphic_File_Type: GIF Data_Quality_Information: Logical_Consistency_Report: Topology for this data set was built using the CLEAN command within ARC/INFO. This command eliminates dangling nodes, calculates inter- sections of arcs, eliminates redundant arcs, and creates an polygon attribute table. Completeness_Report: This data set is a representation of the Coal Fields in the Conterminous United States and Alaska (none in Hawaii). The Trumbull map was the main source of information. The Gulf Coast region was updated using state geologic maps. Team scientists determined that this combination would provide the most up to date information concerning U.S. coal fields Lineage: Source_Information: Source_Citation: Citation_Information: Originator: U.S.G.S Publication_Date: 1908 Title: Coal Fields of the United States (Campbell) Source_Scale_Denominator: 7500000 Type_Of_Source_Media: paper Source_Time_Period_Of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: 1908 Source_Currentness_Reference: Publication Date Source_Citation_Abbreviation: NA Source_Contribution: NA Source_Information: Source_Citation: Citation_Information: Originator: U.S.G.S Publication_Date: 1942 Title: Coal Fields of the United States (Averitt) Source_Scale_Denominator: 2500000 Type_Of_Source_Media: paper Source_Time_Period_Of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: 1942 Source_Currentness_Reference: Publication Date Source_Citation_Abbreviation: NA Source_Contribution: NA Source_Information: Source_Citation: Citation_Information: Originator: U.S.G.S.
