Attribute accuracy was tested by manual comparison of the source with georeferenced digital printouts of the original USGS OFR 96-092
The shapefile is based on the Tully (1996) map, which does not have an entry for Positional Accuracy in its metadata. The coal field labels on the PDF were representations of generalized areas where the coal fields are located. A point was placed in the most likely location for the coal field. This point file should be considered for labeling purposes only.
Data set complete. No data were intentionally omitted from the hard copy and digital source maps.
Map elements were visually checked for overshoots, undershoots, duplicates, polygon closure and proper attribution. All polygons were created from existing shapefiles or coverages that had already gone through the USGS publications process.
Are there legal restrictions on access or use of the data?
