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 P. Jahn during Spring 1995, with a maximum RMS of 0.009. The Pennsylvanian boundary was digitized into a separate coverage by M. Riggs during June, 1995, with a maximum RMS of 0.005
1. There are township and county boundary arcs on the
published map which are not on the mylars. The
corresponding arcs were copied from the COUNTIES
and TOWNSHIPS coverages in the ISGS GIS database
directory *path_name_suppressed*/ILLIMAP
and incorporated into this coverage.
2. The Pennsylvanian boundary arcs were copied into
the coverage.
3. Items for the .PAT and the .AAT files were added
to the coverage.
The .PAT items were:
thick 2 2 i
depth 2 2 i
tons 2 2 i
penn 2 2 i
done 2 2 i
The .AAT items were:
thick 2 2 i
depth 2 2 i
penn 2 2 i
qual 2 2 i
done 2 2 i
The "done" items were used during the attribute coding
phase to indicate whether or not coding of a feature was
complete. When this phase was complete, the "done" items
were deleted from the .PAT and .AAT files.
4. Polygon and arc codes for the coverage were attributed
according to the information depicted on the published
map. In several cases, depth assignments were not obvious
on the published map: in this case the source publications
listed on the published map were consulted in order to
make a depth assignment.

The attributes of this coverage were reviewed in 1995-96 by comparison with the attributes of the source paper map and the lines of the source mylar separate. 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.
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.
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.
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.
