Sulfur Content of the Herrin Coal in Illinois

Illinois State Geological Survey 1998 Sulfur Content of the Herrin Coal in Illinois vector digital data ISGS GIS Database herrn_sulf Champaign, Illinois Illinois State Geological Survey GISDB_COAL_IL_Herrin_Sulfur_Py withheld Sulfur content (pounds of sulfur per million Btu) was mapped for the Herrin (No.6) Coal in Illinois using point source data (primarily channel samples and drill cores), information from coal company geologists, and observation of geologic trends associated with the formation of sulfur in coal. This map was created to show general trends in sulfur content of the Herrin Coal. Because of the nature, quantity, and distribution of source data, the map is suited for use at scales of 1:500,000. 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 1998 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 quality sulfur Herrin none Illinois none This map is suitable for use at scales of 1:500,000.

For general questions about distribution, or availability of other data, please contact the Information Office as listed under the Distribution_Information section. ESRI ArcCatalog 8.3.0.800 Shapefile Sulfur contours were mapped based on point source samples (primarily channel samples and drill cores), interviews with coal company geologists, and observation of geologic trends associated with the sulfur content of coal. Contours were hand drawn and digitized. Because of the nature, quantity, and distribution of source material used to create this map, the map is suited for use at scales of 1:500,000. 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. see above. 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.

Contours were hand drawn and digitized. Because of the nature, quantity, and distribution of source material used to create this map, the map is suited for use at scales of 1:500,000. Coverages created for OFS 1997-4 were unioned and clipped to exclude area outside of Herrin Coal crop. Resultant polygon coverage was created as follows: Step 1 - Perry, Jackson, Jefferson, Franklin, and Williamson county sulfur coverages were mapjoined and polygon attributes were verified Step 2 - joined coverage was added to sul2660. Step 3 - resulting coverage was clipped to Herrin Coal crop and edited Step 4 - polygons coded SULFUR = 0 were re-coded as SULFUR = 3 Step 5 - dissolve suljoin2 coal6-sulfur sulfur poly 1998 polygon edits & item clean-up by Chris Korose. 2003 Metadata imported. withheld Metadata imported. withheld 20040325 10053700 Vector Simple FALSE 0 TRUE FALSE North American Datum of 1983 Geodetic Reference System 80 6378137.000000 298.257222 GCS_North_American_1983 not applicable Explicit elevation coordinate included with horizontal coordinates GISDB_COAL.IL_Herrin_Sulfur_Py Feature Class 0 Shape OBJECTID OID 4 Feature geometry.
