Title
Mylar Mine Portals and Seam Elevations [Pennsylvania]
Description
Points digitized from the historic Mylar tracking system, attributed with fields from BMP spreadsheet of Mylar index cards.A layer containing points of portal entries and coal seam elevations of coal mines. Data was converted over from the physical "Mylar Review" system for surface mine permit location look-ups. The physical topographic maps and mylar overlays have been scanned, georeferenced, and vectorized to create the point layers with an index number attribute. The corresponding index cards have been data entered in a spreadsheet. The point layers' attribute tables were joined with the spreadsheet. More recent coal feature points and attributes were digitized directly as shapefiles. This layer represents a combination of various coal mine tracking systems.
