Illinois Coal Resource Shapefiles

From ILMINES WIKI

Coal resource shapefiles of the Colchester, Danville, Davis, Dekoven, Herrin, Jamestown, Seelyville, and Springfield Coals in Illinois

Below are links to the digital coal resource shapefiles available from the ISGS Coal Section. The listed shapefiles are the same ones that were used to construct the County Coal Map Series maps and State Coal maps.

Important information on the use of these files and other materials

These digital files have been reviewed and edited and meet the standards of the Illinois State Geological Survey with regard to scientific and technical quality and are suited to the purpose and the use intended by the ISGS Coal Section. They present reasonable interpretations of the geology of the area and are based on available data. However, the interpretations are based on data that may vary with respect to accuracy of geographic location, the type and quantity of data available at each location, and the reliability of the data sources. Consequently, the accuracy of unit boundaries and other features shown in these files varies from place to place.

This data set provides a large-scale conceptual model of the geology of the area on which to base further work. Any map or cross section included herein is not intended for use in site-specific screening or decision-making. Use of this document does not eliminate the need for detailed studies to fully understand the geology of a specific site. The Illinois State Geological Survey and the University of Illinois make no guarantee, expressed or implied, regarding the correctness of the interpretations presented in this data set and accept no liability for the consequences of decisions made by others on the basis of the information presented here.

Sources of data and limitations of maps/spatial coverages: The maps/digital files used for these studies were compiled from data obtained from a variety of public and private sources and have varying degrees of completeness and accuracy. The maps are designed for regional assessment and have a resolution of 1:500,000. Features or details of features smaller than about one-half mile across may not be accurately portrayed or may be omitted altogether.

This digital data is expected to be used as-is, and is not to be altered by the user. See metadata text for additional detailed information on the creation of the dataset elements, use constraints, etc.
