• Description:
  Two improved methods have been developed to transfer microfilmed mine maps to suitable base maps showing surface features. The methods provide for (1) positioning and orienting maps, (2) merging adjacent maps, and (3) plotting maps at a common scale. One method produces an overlay mosaic of mine maps using an integrated camera-processor. This photographic method shows the details of mine workings and is most useful for specific limited-area projects. In the second method, outlines of mine maps are digitized, manipulated, and plotted as over-lays using a computer. This computer method can plot mine outlines and spatially index large numbers of microfilmed maps. Microfilmed mine maps used in this Bureau of Mines study are on file in the mine map repository of the Eastern Field Operations Center. The base maps are U.S. Geological Survey 7.5-Minute topographic maps. The demonstration area is located in the new Kensington East and West quadrangles, Pennsylvania. [Description provided by NIOSH]
