Approximate downstream termination points of overburden fills, extracted from the permit tracking database. This data was entered from permit applications, and is less inclusive than the polygon features that were derived from remote sensing and map sources.
permits and associated coordinates, extracted from the permit tracking database. Because multiple permits can be issued over the operational life of a single well, multiple point features can overlap at the same location.
boundaries of post-SMCRA forfeited permits associated with the special reclamation program. Permits that do not have an available boundary map are represented as circular features centered on a point coordinate, sized to to the permitted acrage, when available.
WVDEP Lidar data was collected by the Natural Resource Analysis Center at WVU under contract with the West Virginia Department of
Environmental Protection, Division of Mining and Reclamation.
The data was collected between 04/09/2010 and 12/13/2011 during leaf-off, snow and flood free conditions in the spring and fall.
This is now an historical elevation data source. More current lidar is now available through the USGS 3DEP program.
The data format is 1.5x1.5 km LAS v1.2 files in UTM 17 NAD83 (CORS96), NAVD88 (GEOID09). Contractor software initially classified
ground returns for comprehensive and bare earth tiles, but did not perform other classifications. The Technical Applications and GIS (TAGIS)
unit at the WVDEP performed Quality control checking and error correction on a tile-by-tile basis before creating derived products and edited
