Illinois State Geological Survey 1999 vector digital data ISGS GIS Database herrn_tk Champaign, Illinois Illinois State Geological Survey GISDB_COAL_IL_Herrin_Thickness_Py withheld Thickness contours of 28", 42", and 66" were mapped for the Herrin (No. 6) Coal in Illinois. This datafile was created from public data only. The term "insufficient data" is used in the delineation of areas where the coal is known to be thin (less than 18 inches thick) or absent, or ares where there is insufficient thickness data for resource calculation and mapping. 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 1999 publication date of sources Complete Irregular -90.607665 -87.495214 41.477282 37.602945 -90.607665 -87.495214 37.602945 41.477282 none geology coal coal thickness Herrin 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 Herrin Coal thickness isopachs were updated for Douglas, Edgar, Coles, Clark, Cumberland, Effingham, Jasper, Crawford, Richland, Lawrence, White, Macoupin, Montgomery, Shelby, Moultrie, Bond, Fayette, and Clinton counties in 1996. The updated resource coverages were used for these counties. The thickness values for the remaining counties were extracted from previous resource coverages. Any discrepancies were compared to the original source paper map or mylar separate. Isopachs are based on public data available to the ISGS at the time of the original map compilation. Accuracy of this compilation is dependent on the locational and measurement accuracy of the original data points, the distribution of data points, the local variability of the coal seam and other factors. 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. In areas of limited data, boundaries have been generalized using section lines and/or county boundaries. 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.

The purpose of this project was to extract only the thickness isopachs for the seam and subsequently show only the 28", 42", and 66" thickness polygons. The extracted isopachs were compared to existing drill hole data for accuracy and confidentiality. Isopachs created from confidential data were not used. The resultant polygon coverage was created as follows: Step 1 - calc thickness of polygons RES THICK GE 66 CALC THICK = 66 AS RES THICK > 0 AND THICK LT 30 CALC THICK = 22 AS RES THICK GE 30 AND THICK LT 42 CALC THICK = 28 AS RES THICK GE 42 AND THICK LT 66 CALC THICK = 42 AS RES CTYPE96 (or CTYPE94) = 2 CALC THICK = 2 AS RES CTYPE96 (or CTYPE94) = 3 CALC THICK = 3 AS RES CTYPE96/94 = 5 CALC THICK = 5 RES CTYPE96/94 = 6 CALC THICK = 6 RES CTYPE96/94 = 9 CALC THICK = 9 Q STOP Step 2 - the coverage was checked to determine that the universe polygon thickness had a value of zero. Step 3 - the coverage was reviewed for other polygons with thicknesses of zero. If these polygons were outside the crop they were calced to 0. Step 3 - a point coverage was created from the Coal Sections' INFO database that showed the coal thickness and confidentiality status of the drill hole. This point coverage was overlaid on the above resource coverage, and it was determined whether the thickness isopachs were justified by public data points. Isopachs based mostly on confidential data points were removed.

Each region was reviewed for discrepancies across county boundaries, and edited accordingly. join1 = Henry, Bureau, LaSalle, Grundy, Stark, Marshall, Putnam, Livingston, join2 = Knox, Peoria, Tazewell, Fulton, Logan, Macon, Sangamon, Morgan, and Scott counties. join3 = Christian, Shelby, Moultrie, Douglas, Edgar, Coles, Champaign, and Vermilion counties. join4 = Greene, Jersey, Macoupin, Montgomery, Madison, Bond, Fayette, Marion, Clinton, Washington, St.Clair, and Monroe counties. join5 = Clark, Cumberland, Effingham, Jasper, Crawford, Clay, Richland, Lawrence, Wabash, Edwards, and Wayne counties. join6 = Randolph, Perry, Jackson, Jefferson, Franklin, Williamson, Hamilton, Saline, Gallatin, and White counties. Step 6 - After editing, the 6 regions were eventually mapjoined as one coverage, join111. In this coverage all mines and mine boundaries (thick = 6 or thick = 9) were calced to the predominant thickness in the area (be it 22", 28", 42", or 66"), using both ArcEdit and ArcView. Step 7 - dissolve join111 jdis-state3 thick poly Step 8 - edit sliver polygons in jdis-state3 Step 9 - Pieces of the #6 crop that were needed were pulled from /coal3/coal-resources/statemaps/coal6-84 and put to jdis-state3.
