The Nation's coal resources are being reassessed by the USGS. This assessment identifies and characterizes the coal beds and coal zones that will provide the bulk of the nation's coal-derived energy during the next century. This assessment is different from previous large-scale USGS assessments because files and databases are being stored in a digital format and are being analyzed using a Geographic Information System (GIS).
USGS, Unknown, 1:250000 Digital Elevation Models: U.S. Geological Survey Digital Elevation Model All tiles necessary for coverage of Yampa coal field..
1:250000 scale 3 arc-second Digital Elevation Model (DEM) data. Some elevation data at the edges of individual tiles were processed for edge-matching purposes.
same accuracy as USGS 3 arc-second DEMs.
No topology present in raster image.
