This dataset is a polygon coverage of the resource areas of the Lower Kittanning coal zone. The polygons are subdivided into 2 categories: resource areas inside the outcrop, and areas either too thin, outside the outcrop, or beyond data collection limits. The coal zone must contain at least 14 inches of coal to be a resource. This spatial data set of the Lower Kittanning coal bed and known mined areas is one of many Geographic Information System (GIS) products of the National Coal Assessment that is being conducted by the U.S. Geological Survey in cooperation with State geological surveys and other Federal and State agencies. The Lower Kittanning coal bed is an important economic coal in the northern part of the...

The Pittsburgh coal bed is composed of regionally persistent divisions- a roof division (coals and shales) and a lower division, referred to as the "main bench". This dataset is a polygon coverage of the elevation of the top of the Pittsburgh Coal bed main bench, in feet above MSL. It was produced by gridding (producing 300 meter cells) 7,101 point-source data mainly from the National Coal Resources Data System (NCRDS) of the USGS, using ISM (Version 7.1) software. The grid was subsequently contoured in 50-ft intervals and imported to ARC/INFO. The elev_st item for each polygon reflects a value halfway between the bounding contour lines. Coverage name: c9024st (024 is the bed code assigned to the Pittsburgh Coal...
