The U.S. Geological Survey (USGS) is undertaking a five year effort to identify and characterize coal beds and coal zones that could provide the fuel for the Nation's coal-derived energy during the first quarter of the 21st century. As part of this National Coal Assessment, Hettinger and others (1996) have completed an assessment of the coal deposits in the John Henry Member of the Straight Cliffs Formation, Kaiparowits Plateau of southern Utah. Their report delineates the distribution of coal and provides estimates of resources in the basin.
It also serves as a basis for future efforts to assess coal resources and determine availability and recoverability. A fundamental component of their work was the digital geologic and geographic data compiled in a Geographic Information System (GIS). Use of this GIS allowed for the spatial integration of data layers, and resulted in the ability to display, analyze, and query data and produce information that are useful for land-use planning and to answer complex geo-spatial questions concerning coal resource occurrence.
This coverage is intended as a basemap layer for GIS applications at a scale of 1:125,000 or less.

The contour output file was then run through the ISMARC program that converts the contour output file into an arc generate file. The arc generate file is then converted to a polygon coverage in Arc/info by using Colin Treworgy's aml "convert-ism". The coverage used to clip the contours in every case was the 'csb' coverage. Following is a description of the parameters used in gridding the scattered data files to generate the grids in ISM:
Coordinate system: Universal Transverse Mercator (UTM) Units: Meters UTM zone: 12 Ellipsoid: Clarke 1866 Semi-major axis in meters: 6378206.4 Semi-minor axis in meters: 6356583.8 Grid size: 276 by 312 Grid range: 407508,503665 4098129,4203271Treworgy's aml "convert-ism" assigns a value to the item DEPTH, which we changed to THICK, by taking one-half the contour interval and adding it to the minimum contour that defines a polygon. For example, if the contour interval is 10, and a polygon is bounded by the 10 and 20 contour lines, then the THICK value assigned to that polygon is 15.
