The final product served a two-fold purpose of mine reclamation and identification of surrounding abandoned mine shafts and tunnels. DDS obtained the historical maps from the Colorado Division of Minerals and Geology for each project. Each map was scanned on large-format scanners at 400 DPI and georeferenced to the client-specified projection. DDS vectorized and attributed all the mine workings and shafts as the source maps were drawn. Attributes collected included: mine names, well numbers, shaft names, and coal seam designations.
