Abstract: Digital Geology of Colorado - 1997

R. L. SANDEFUR

More and more geological Previous HitinformationNext Hit is now available in digital format from government and other sources. Digital Previous HitinformationNext Hit 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 Previous HitInformationNext Hit

To be most useful this Previous HitinformationNext Hit must be integrated with other digital Previous HitgeographicNext Hit Previous HitinformationNext Hit including:

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

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