In addition, arcs are coded to indicate the Pennsylvanian boundary, depth to (top surface) of coal (contours), and 28" and 42" coal isopach lines. This is the automated version of the Coal Resources Map for Danville (No. 7) Coal by J.D. Treworgy and M.H. Bargh (1984). This data set has a scale of 1:500,000. Purpose: This data set was created as part of the ISGS GIS database to show distribution, thickness, depth, and tonnages for the Danville (No. 7) coal seam. The data are appropriate for regional analysis.

Source accuracy was not addressed in that review. A variety of visual techniques (polygon shading, line shading and line thicknesses tied to attribute values) and GIS processing techniques (checking for logical consistency) were used. Attribute values for arcs were verified by generating plots with arcs color-coded by designation. These were visually checked for errors. Polygon attribute items values were verified in a similar manner. For example, thickness and tonnage were checked by plotting maps with a unique color/symbol pattern for each possible combination. These check-plots were visually inspected for the proper designations, and all other polygon attributes were verified in the same way. In cases of incorrect or ambiguous attribute values, the sources of the source paper map were consulted, and corrections made. These reviews were performed in an iterative fashion by two or three individuals. There are no arc or polygon attribute values outside the appropriate value domains. Logical_Consistency_Report: 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. Completeness_Report: Mine boundaries are current as of 1984 and have not been updated since. Many coal seam boundaries have been generalized using section lines and/or county boundaries because the source data are proprietary. Not all coal seams in Illinois are included. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: 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. See Completeness Report. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: Treworgy, J.D. and M.H.

Process_Date: 1995 Process_Step: Process_Description: Digitizing: The coverage was digitized from the mylar separates that were used in the printing of the published hard copy maps. The separates were obtained from Colin Treworgy, ISGS Coal Section. Three separates were used: > 1) black line separate, representing all boundaries of coal bodies, > 2) red line separate, representing the 150 foot depth line, and > 3) Pennsylvanian boundary separate. Separates were digitized at the 1:500,000 scale on a GTCO Super L II digitizing board. Red and black lines were digitized by M. Riggs during February 1995, with a maximum RMS of 0.007. The Pennsylvanian boundary was digitized into a separate coverage by M. Riggs during June, 1995, with a maximum RMS of 0.005. Process_Date: 1995 Process_Step: Process_Description: Processing > 1.

Process_Date: 1995 Process_Step: Process_Description: Revisions: Prior to 10-10-95 no version numbers had been assigned to this coverage. The previous coverage that partially depicted this data will heretofore be assigned as version 1.0, and this coverage is version 2.0. Process_Date: 1995 Process_Step: Process_Description: Reviews Applied to Data: In Summer and Fall 1995 the coverage underwent extensive Quality Assurance/Quality Control review as a preliminary step. Linework was verified by overlaying a plot of the arc on the original mylars. Digitized arcs within one line-width of the original linework were deemed acceptable. Those outside one line-width were corrected. Attribute values were verified by comparing a set of plots (that depicted the value of the .AAT or .PAT attribute) with the published maps. The AML programs used to generate the check plots are called COALPLOT.AML, COALLINE.AML and COALPENN.AML.
