Why was the data set created?

The Nation's coal resources are being assessed by the USGS. A fundamental component of this assessment work is to compile digital geologic and geographic data into a GIS. Use of this GIS allowed for the spatial integration of data layers. This resulted in the ability to display, analyze, and query to answer complex geo-spatial questions concerning coal geology and resource occurrence.

How was the data set created?

1. From what previous works were the data drawn?

   (source 1 of 1)

   Indiana State Geological Survey, 1992, The Indiana Coal Analysis Database; Computer database 1: Indiana State Geological Survey, Bloomington, Indiana.

   Type_of_Source_Media: pdf digital files

   Source_Scale_Denominator: 24000

   Source_Contribution: Spatial and attribute information

2. How were the data generated, processed, and modified?

   Date: Jul-1999 (process 1 of 1)

   Data for the Illinois Basin assessment consists of geologic and chemical information. The samples are representative of the coal beds and were carefully selected to provide an accurate view of the overall coal quality throughout the Basin. Samples for the Illinois Basin are primarily from face channels in mines or from drill core. This GIS layer was created from "The Indiana Coal Analysis Database; Computer database 1", 1992 by Walter A. Hasenmueller and Louis V. Miller. Indiana Geological Survey. The following files (igschm1l, igschm1c, igschm1r, igschm2l, igschm2c, igschm2r, igschm3l, igschm3c, igschm3r) were merged and modified. Samples from this merged file were retrieved if they were less than 50% ash yield, and within the Illinois Basin study area of Illinois, Indiana, and Western Kentucky. All samples were edited for geological and chemical information and were updated to reflect new changes. This data set is therefore a modified subset of "The Indiana Coal Analysis Database; Computer database 1". This data set is stored as an ASCII text file (inspchms.txt). In ArcView the text file was added as a table, the table was added as an event theme, and then the theme was converted into a shapefile. For additional information on the structure of this Indiana chemical data set see the Indiana chemical terms file (inchmtrm.pdf).
