Historic Mine Digitization

Historic Mine Digitization- Converting Hand Drawn Historic Mine Drawings into GIS to Aid in Permitting & Safety

Colorado Department of Natural Resources Division of Reclamation Mining & Safety The Colorado Division of Reclamation Mining and Safety is responsible for mineral and energy development, policy, regulation and planning. The division is comprised of the Office of Mined Land Reclamation and the Office of Active and Inactive Mines.
The objective of this project was to provide digital GIS files of certain abandoned mines in the state of Colorado. This entailed converting hard-copy documents into a mapping system (GIS), so that the approximate location of the mines would be readily available and analyzed with current aerial photography, land planning, and land use maps.

The data source provided by CDNR included 420 original surveyed hard-copy maps on mylar, paper, and linen. Field collected GPS data, public land survey data and aerial photography, supplied by DDS, was used as control for the  placement of the mine drawings into their proper spatial location.
Individual maps and plates were scanned on large-format color scanners. The scanned images were georeferenced to best available controls. RMS error, control sources, and operator notes were recorded for each image. Mine features such as worked out areas, mine workings, faults, adits, slopes, permit boundaries, property boundaries, and other miscellaneous features were digitized and attributed according to client specifications.   Final deliverables were a series of shapefiles, (.shp) ESRI personal geodatabases, and extensive metadata files describing the source documents and the processes used for data conversion.  A "Statement of Process" document was also created to serve as a specification manual for future digitization projects.	Analysis of Historic  Information Aid in Effective Prevention and Response to Mining Related Disasters GIS Conversion and Attribution
This data would be used by miners, geologists, contractors and other entities to safely plan and route around these abandoned mine shafts. The geospatial data also allows for a more focused and effective response to disaster should a collapse occur.	Helping you make better decisions through information... Digital Data Services, Inc.
