Abstract: Previous HitDigitalNext Hit Geology of Colorado - 1997

R. L. SANDEFUR

More and more geological information is now available in Previous HitdigitalNext Hit format from government and other sources. Previous HitDigitalNext Hit information available for Colorado includes:

  • A geological map of the state at 1:500,000
  • Various 1:24,000 (7.5 minute) geological maps
  • The NURE data base (Geochemical Data)
  • Geological age Data Base
  • Coal and Oil and Gas Information

To be most useful this information must be integrated with other Previous HitdigitalNext Hit geographic information including:

  • Scanned topographic maps (DRGs)
  • Previous HitDigitalNext Hit Ortho Quads (DOQs), (3) Remote Imagery (SPOT, etc.)
  • Previous HitDigitalNext Hit Elevation Models (DEMs)
  • Previous HitDigitalNext Hit Line Graphs on roads, water, and political boundaries (DLGs)
  • Survey coordinates and markers (GCDB) Land Use and Land Cover (LULC) Geographic Names (GNIS)
  • Previous HitDigitalNext Hit text and maps and sections scanned from paper copy reports

This paper discusses sources of information and some of the difficulties in integrating various formats and coordinate systems. The specific example used is the development of a computer program which allows the 1:500,000 Previous HitdigitalNext Hit geological map of Colorado to be used with a Global Positioning System (GPS).
