Description:

Abstract:: This ArcView shapefile contains a representation of the thickness of overburden above the Ferris 23 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.
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 data to generate a grid in ARC/INFO that represented the elevation of the topology (surface elevation) in the area of the Ferris 23 study limit.

Process_Step:

Process_Description:

Stratigraphic data were compiled in a relational database. These data were correlated and the coal and rock above, within, and below the Ferris 23 coal zone were labeled. Stratigraphic data for the coal and rock units within the Ferrris 23 coal zone were downloaded from the database. These data were loaded into a EarthVision (EV) software program. The elevation at the top of the zone was then gridded in EV using the normal minimum tension grid option, four multiple data points (number of closest control points used for calculating a grid value), and a 500 x 500-meter grid spacing. The ARC/INFO DEM coverage (with 500 x 500-meter data spacing) was imported into EV, defined as a grid file, and clipped to the same lateral extent as the EV grid of the top of the coal zone. Using the EV formula processor, the top of the coal zone grid was subtracted from the surface elevation (DEM) grid to create a (minimum) overburden grid. An isopach map was then generated from this grid, with a constant contour interval of 100 ft, and saved to a file in ASCII format. The ASCII file was modified using a custom program called ismarc. The modified file was imported into ARC/INFO and generated as a polygon coverage using an Arc Macro Language (AML). The AML clipped the coverage to the study extent and assigned the overburden thickness polygons with values that are the average of the values of the bounding isopach lines (for example, a polygon defined by isopach lines of 100 and 200 ft was assigned an overburden thickness attribute of 150 ft). A new item was then added to the polygon attribute table and populated with text labels corresponding more closely to overburden categories that we were to use for coal resource tables and graphic display (0-100 ft, 100-200 ft, 200-300 ft, 300-400 ft, 400-500 ft, 500-1,000 ft, 1,000-2,000 ft, 2,000-3,000 ft, 3,000-4,000 ft, and

4,000 ft). The polygon coverage was then dissolved

based on the text labels. The final coverage was projected to geographic and made into a shapefile in ArcView.
