Iowa Department of Natural Resources, Geological Survey Bureau,
Open File Report 90-2, 1990, 70 p.
Remaining coal resources were evaluated in Monroe County, Iowa, using the Iowa Department of Natural Resources - Natural Resources Information System. Total resources of 972,237,477 tons of coal were determined for the Whitebreast, Laddsdale, Cliffland, and Blackoak coal beds. The project provided tests of many of the functions of the pcARC/INFO component of the Natural Resources Geographic Information System which may be used to evaluate extractable resources. The system provided tools to: 1) manage resource-related data, 2) exchange various types of data with programs outside pcARC/INFO, 3) analyze spatial data and use the results to calculate volumes, and 4) display the result as tables or maps. The methods used in the coal resource assessment were evaluated and results obtained were compared to previous coal resource estimates.
