Coal Fields of the United States: Map Layer Description File

This map layer portrays areas that contain significant coal deposits for Alaska and the lower 48 States of United States. The layer contains the name of the coal field or region, the type of coal and if it is minable. The types of coal included are lignite, bituminous, subbituminous, and anthracite. The Department of Energy Fossil Fuels education site has information about the types of coal.

Metadata

What follows is very detailed technical information about this map layer. This is often called metadata. Metadata (or "data about data") describe the content, quality, condition, and other characteristics of data. Metadata are used to organize and maintain investments in data, to provide information to data catalogs and clearinghouses, and to aid data transfers. The Federal Geographic Data Committee (FGDC) publishes the Content Standard for Digital Geospatial Metadata. Many organizations within and outside of the federal government have adopted the FGDC metadata standard and are using automated indexing and serving mechanisms to provide access to their holdings through the Internet. Visit the FGDC Clearinghouse to learn more about how metadata is used in clearinghouses and to search for other data sets.

Description:

Abstract:: This data set shows the coal fields of Alaska and the conterminous United States. Most of the material for the conterminous United States was collected from James Trumbull's "Coal Fields of the United States, Conterminous United States" map (sheet 1, 1960). 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" map (sheet 2, 1961).
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 1:5,000,000-scale data. No responsibility is assumed by the U.S. Geological Survey in the use of these data.

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 intersections of arcs, eliminates redundant arcs, and creates a polygon attribute table.

Completeness_Report:

This data set is a representation of the coal fields in the conterminous United States and Alaska. There are no coal fields in Hawaii.

Process_Step:

Process_Description:: All the paper maps were manually digitized on a tablet using Arc/INFO. All data were then appended into one data set. This data set was edited to resolve inconsistencies between maps and to form a polygon coverage. The final data set was then attributed using the coaltype codes described within this document.
