Abstract:
Remaining cumulative (net) thickness of mapped coals, greater than 18 inches thick, in Illinois. Existing polygons of detailed coal thickness isopachs for 26 seams were compiled and added together, and are summarized as areas of coal thickness classified in increments of 5 feet. Areas of individual coal seam thicknesses less than 18 inches were excluded from the summation. Mined areas were also excluded from the summation. Areas containing confidential data have been omitted from this dataset.

This map was created as part of a preliminary coalbed methane resource assessment conducted by the ISGS.

Purpose:
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.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Coal thickness isopachs were updated by county and seam per coal resource assessments and/or coal availabilty studies specific to the coal seam. Isopachs for the individual coal seams are based on data available to the ISGS at the time of the original map compilation, and were originally contoured at intervals ranging from 2 to 12 inches, typically at 6-inch intervals. 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, the differing extents of coals mapped in Illinois and/or the differing extents and detail of thickness mapping for these coal seams, the summation of thickness data from multiple vertically-stacked seam-specific polygon sources, and other factors. This dataset is an attempt at using the detailed thickness polygons to estimate cumulative coal thickness in Illinois and is not meant to represent an isopach map from individual data points that could contain cumulative coal thickness information. This dataset is intended for use at a scale of 1:500,000.
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:
In areas of limited data, boundaries have been generalized using section lines and/or county boundaries.
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.

Process work and notes by CC: The procedure was to adapt cpk's amls from various availability projects and calc tonnage for the Keystone writeup to get amls that do what we need.

A couple of false starts involved going to the library to dissolve the various res covers to thickness covers over here in the cbm space. Besides hitting the snag that the res2660 covers wouldn't dissolve or mapjoin, we realized that after dissolving, we could no longer easily get back the areas that should have thickness = 0 (outside the crop, in channels, in areas of insufficient data, and mined-out areas). Thus, we needed to copy the res covers to the cbm space (copy_res.aml), then update them for this purpose.

calc-thick-0.aml reselects for ctype = 3, 5, 6, or 9 and then calcs thick = 0; runcalc0.aml runs calc-thick-0.aml for each specific res cover.

  CTYPE96
1  Minable coal
2  Split coal
3  Channel
4  Less than 150' deep (Not used for CTYPE96.  This was used for earlier CTYPEs)
5  Insufficient data
6  Mined-out area
7  Outside crop
8  Non-study area
9  Unminable area between mines
10 Coal too thin
then rundis_all.aml invokes dis.aml for each specific res cover that had been copied over; dis.aml dissolves on the item THICK so that only the polygons referring to thickness are left. rundis_all does this for each res cover, so that coverages named tk[fips #]_ [seam] were created.

then join_all.aml was run to mapjoin all thickness coverages created in the last step for each seam. -note, seam 2660 was omitted; due to problems with the input res covers, these need to be treated separately (it makes the process hang; they may not join at all; how 2660 Herrin seam was treated will be described separately)

Then the item THICK needs to be altered in info so that when the different seams are unioned, it will be clear which seam has what thickness. Otherwise, the item THICK will be overwritten with each successive union, and there would be no way to calculate a cumulative thickness. alter.aml alters the item THICK (a 3,3,I item) to seam-specific thick items

** NOTE: this did not work, I did them by hand. first i had an aml that did it by itself, but it would not run due to error in the &data arc info line. so then i copied the format of runcalc0.aml and made an aml that should have worked by invoking an altr.aml for each one, and it did go in & out of info, but it did not make the alterations and i don't know why. check w/ cpk. it was taking longer to make the aml than to do it by hand, so i just did it, but i'd like to know why it did not work.

****** start here, messing w/ #6; PROBLEMS FROM MAPJOINS OF RES COVERS
	RECORDED IN join_2660.aml 9it stopped being an aml when it didn't
	run and i recorded what worked and what didn't in that file)

/coal14/avail/herrin/all-layers/transfer-to-usgs/thick6
	note that herrn_tk in /cbm/thick has codes like 2, 3, 5 for ss channel,
	insuff. data, thin coal.  these would be treated like inches, so this
	thick6 cover is the better one to start with.
   need to union with a statewide mines cover
	note that I can't reselect the ctype = 6  (Mined-out area) and ctype =
	9  (Unminable area between mines) from the res covers because i'd
	get the same problem of not being able to put them together as i
	did with the whole and dissolved versions of the res covers. I will
	have to assume that the unminable area between mines is negligible.
	   As it turns out, I should be able to get ctype = 9 by using the
	   type = A in the mine coverage.
   then calc the mined areas to thick = 0
	(first check that item thick is 3, 3, i), YES!

Process_Description:
The resultant summation coverage was compared to areas containing confidential data, and thickness polygons were edited to remove reference to this data in selected areas. The draft net thickness layer contained numerous small polygons over a wide range of thickness values. To aid display, filesize, and use, this layer was then 'dissolved' into areas of 5-foot thickness increments. -cpk
