Structure contours of the Pittsburgh coal bed in Pennsylvania, Ohio, West Virginia, and Maryland

Summary

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 bed). The coverage [...]
