Polygon and chain-node topology is present. The original ArcInfo coverage was checked for complete chain-node topology (no dangling arcs, except where appropriate), polygon labels (one per polygon, except for universal polygon), correct regions topology, boundary values appropriate for map projection and map units, and appropriate "fuzzy" tolerances. There are no known arc, polygon or region attribute values outside the appropriate value domains. The coal crop was updated from previous mapping in selected areas as a function of coal resource coverage updates. Where Coal Section coal resource county coverages were updated and sufficient new information was available, areas near the known crop of the the coal were further studied. An Earthvision grid of the elevation of the coal was compared with the elevation of the bedrock, and where these two grids intersected was delineated as the crop of the coal. Any discrepancies were compared to the original source paper map, mylar separate, or previous coverage. This is a generalized depiction of regional ground condition. Horizontal positional accuracy was verified by manual overlay of source and hard-copy plots. Arcs within line-width of source maps are deemed acceptable. For positional accuracy of source maps, contact the ISGS Coal Section.
