This ARC/INFO point coverage represents the non-confidential, point- source stratigraphic data in Indiana that was used to map the structure and thickness maps of the Danville Coal for the National Coal Assessment.

This is a polygon coverage containing eleven different attributes of information including net coal thickness and estimated coal tonnages in the Calico and A-sequences in the Kaiparowits Plateau study area. This layer was derived from a "union" process, i.e., intersection and overlay of numerous layers and retaining attributes of each. It is the result of computing the geometric intersection of ten polygon coverages using the Environmental Systems Research Institute, Inc. (ESRI) Arc/Info UNION command, and finally calculating coal tonnage in INFO. Net coal thickness values are from 209 data points and represent all coal beds that are more than 1 foot thick.CARE SHOULD BE TAKEN IN USING THE COAL THICKNESS AND COAL...

This dataset represents the thickness of the potentially minable Fire Clay coal benches in Virginia, West Virginia, and Kentucky. The coal zone is known by other names, depending upon locale. The data were comprised of values from Kentucky in EXCEL format, data searched from the USGS' NCRDS database for Virginia and entered into StratiFact, and a StratiFact database obtained from the West Virginia Geological and Economic Survey (WVGES). Point data were gridded, the grid contoured and imported to ARC/INFO as polygons. The Kentucky portion was replaced by a polygonal thickness coverage obtained from the Kentucky Geological Survey that had been manually contoured, therefore State line discrepancies are to be expected....

This data set was developed from a Bureau of Land Management database containing information on coal thickness from core samples, converted into a spatial database using kriging techniques. The data set covers the Little Thunder Creek watershed in the Powder River Basin, Wyoming. Each polygon is attributed with reference to a range of thickness describing the coal seam (measured in feet).

This ArcView shapefile contains a representation of the net coal thickness in the Ferris 50 coal zone in the Ferris coalfield, Hanna Basin, Wyoming. This theme was created specifically for the National Coal Resource Assessment in the Northern Rocky Mountains and Great Plains Region.
