      Origin:  Mining and Reclamation Plan (MRP) maps are required to be 
               submitted with an application for a permit to conduct surface 
               coal mining and reclamation operations in the commonwealth of 
               Kentucky. MRP maps are generally drawn on an enlarged USGS 
               7 1/2-minute topographic map at a scale of 400 or 500 feet to 
               the inch and show the permitted surface and underground mine 
               boundaries. Many MRP maps have been scanned and georeferenced 
               and are available for downloading from the Internet. When the 
               map is scanned and georeferenced, a polygon is generated 
               representing the extent of the dimensions of the paper map.  
               Digital MRP map files are named with the associated permit number 
               and an extension indicating whether the permit is an original 
               permit (org, nw, new), an amendment (am, amd), revision (rev), 
               mid-term (mt), field revision (frev), minor revision (mi), major 
               revision (ma), succession (su), or a renewal (rn). Some maps 
               contain multiple sheets, in which case a sequential letter is 
               appended to the end of each filename. 

  Attributes:  Information describing each MRP map polygon is contained in the 
               dBASE file, mrpmaps.dbf. Each record contains the 
               following items:

                  Permit_No - permit number
                  MapName   - filename of scanned MRP map
