	Description:
		Abstract:
			This ArcView shapefile is a polygon representation of the
			area of the Gillette Coalfield.  This theme was created
			specifically  for the National Coal Resource 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 collected and stored in
			standardized formats, and being analyzed using a
			Geographic Information System (GIS).

			Source_Contribution:
				This source provided the necessary township and range
				lines to create the western boundary of the Gillette
				coalfield study area boundary.
		Process_Step:
			Process_Description:
				The eastern section of the Gillette coalfield  polygon was
				derived
				from Kent's map.  This section was scanned and
				digitized using automated line following techniques.  The
				northern, southern, and western portions of the map were
				derived from township and range  lines from a USGS digital
				map.  These
				lines were extracted from the source data and pasted into
				the Gillette polygon.  The eastern section was then joined
				with this section to create a polygon.  The coverage was
				projected to geographic coordinates and made into a
				shape file in ArcView.
