| The digital database of coal ownership status is a component of the USGS Energy Resources Program's Federal Lands Assessment project. The project's objective is to develop GIS coverage of coal resources on Federal lands, which in turn allows for an accurate, reliable, and timely analysis of the quantity, quality, and availability of those resources. | ||
