This map was created as part of the National Coal Resource Assessment being conducted by the USGS. These data are appropriate for use in local and regional thematic analysis. The data are not appropriate as a geodetic, legal or engineering base. The data set was not and is not intended as a substitute for surveyed locations, such as can be determined by a registered Public Land Surveyor. Although useful in a GIS as a reference base layer for maps, the data set has no legal basis in the definition of boundaries or property lines. en 2002 publication date of sources Complete Irregular -90.498626 -87.495214 41.447104 37.602945 -90.498626 -87.495214 37.602945 41.447104 none geology coal crop outcrop subcrop Danville none Illinois none Reproduction or redistribution of copyrighted digital data sets or products derived therefrom outside of licensee's organization or entity is expressly forbidden.

For general questions about distribution, or availability of other data, please contact the Information Office as listed under the Distribution_Information section. ESRI ArcCatalog 9.2.2.1350 Shapefile Accuracy of this compilation is dependent on the locational and measurement accuracy of the original data points or maps, the distribution of data points, the local variability of the coal seam and other factors. Polygon and chain-node topology is present. The 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.
