	Description:
		Abstract:
			This coverage contains a representation of the well
			locations in the Gillette Coalfield.  This theme was
			created specifically  for the National Coal Resources
			Assessment in the Northern Rocky Mountains and Great
			Plains Region.
		Purpose:
			The Nation's coal resources are being assessed by the
			USGS.  This assessment identifies and characterizes
			the coal beds and coal zones that will provide the bulk of
			the Nation's coal-derived energy during the next few
			decades.  This assessment is different from previous USGS
			assessments because digital files and databases are being
			stored in standardized formats, and being analyzed using a
			Geographic Information System (GIS).

		This dataset is meant for general display and query
		purposes only in the ArcView Project and should not be
		used for any other purpose.  Terminated, confidential and
		interpretive points have been removed from this dataset.
		In addition, the net coal thickness values within this
		dataset have been modified from their original value for
		resource calculation purposes.  A complete dataset can be
		obtained from the United States Geological Survey's,
		National Coal Resource Data System.

		Process_Step:
			Process_Description:
				Stratigraphic data were compiled in a Stratifact relational
				database. These data were correlated and the coal beds
				were identified. Stratigraphic data for the coal and rock
				units in the  coal zone were downloaded from Stratifact
				and run through a
				custom "parting/split" program to calculate net coal
				thickness at each data location.
				This dataset was then linked to all available coal quality
				samples on the following parameters.  The latitude and
				longitude, surface elevation, and coal top and bottom
				(thickness) for each coal location  was compared to the
				latitude and longitude, surface elevation, and coal top and
				bottom (thickness) each stratigraphic location.  When a
				match was found, the two files were given the same
				identification code.   This identification code linked both
				the stratigraphic and coal quality databases.  Coal quality
				data that could not be match with the corresponding
				stratigraphic data was only utilized for summary tables and
				bubble maps.
				This joined dataset was then imported into ArcView and
				converted to a shapefile.
