Summary

This is a polygon coverage containing eleven different attributes of information including net coal thickness and estimated coal tonnages in the Calico and A-sequences in the Kaiparowits Plateau study area. This layer was derived from a "union" process, i.e., intersection and overlay of numerous layers and retaining attributes of each. It is the result of computing the geometric intersection of ten polygon coverages using the Environmental Systems Research Institute, Inc. (ESRI) Arc/Info UNION command, and finally calculating coal tonnage in INFO. Net coal thickness values are from 209 data points and represent all coal beds that are more than 1 foot thick.CARE SHOULD BE TAKEN IN USING THE COAL THICKNESS AND COAL TONNAGE VALUES CONTAINED [...]

Purpose

The U.S. Geological Survey (USGS) is undertaking a five year effort to identify and characterize coal beds and coal zones that could provide the fuel for the Nation's coal-derived energy during the first quarter of the 21st century. As part of this National Coal Assessment, Hettinger and others (1996) have completed an assessment of the coal deposits in the John Henry Member of the Straight Cliffs Formation, Kaiparowits Plateau of southern Utah. Their report delineates the distribution of coal and provides estimates of resources in the basin.It also serves as a basis for future efforts to assess coal resources and determine availability and recoverability. A fundamental component of their work was the digital geologic and geographic data compiled in a Geographic Information System (GIS). Use of this GIS allowed for the spatial integration of data layers, and resulted in the ability to display, analyze, and query data and produce information that are useful for land-use planning and to answer complex geo-spatial questions concerning coal resource occurrence.This coverage (allcoal) is intended for planning purposes, to be a guide to where the thickest net coal areas are likely to be. This coverage (allcoal) provides the ability to create complex queries based on the limitations of the net coal method. (application at a scale of 1:125,000 or less)
