Group: Summary
  Conversion of the geologic map of the U.S. to a digital format
  was undertaken to facilitate the presentation and analysis of
  earth-science data.  Digital maps can be displayed at any scale
  or projection, whereas a paper map has a fixed scale and
  projection.  However, the geology on this disc is not intended to
  be used at any scale finer than 1:2,500,000.
  
  This CD-ROM contains a digital version of the Geologic Map of the
  United States, originally published at a scale of 1:2,500,000 (King
  and Beikman, 1974b).  It excludes Alaska and Hawaii.  In addition to
  the graphical formats, the map key is included in ASCII text.
  
  A geographic information system (GIS) allows combining and
  overlaying of layers for analysis of spatial relations not readily
  apparent in the standard paper publication.  This disc contains only
  geology.  However, digital data on geology, geophysics, and
  geochemistry can be combined to create useful derivative products--
  for example, see Phillips and others (1993).
  
  This CD-ROM contains a copy of the text and figures from
  Professional Paper 901 by King and Beikman (1974a).  This text
  describes the historical background of the map, details of the
  compilation process, and limitations to interpretation.  The digital
  version of the text can be searched for keywords or phrases.
  
  For DOS users, the CD-ROM contains menu-driven analytical software,
  in which the user selects from an array of topics.  The CD-ROM also
  contains MAPPER display software, a user-friendly package that
  displays the interactive vector map.  The raster image of the
  geologic map can be displayed with VIEWLBL.
  
  For other types of computer users, the map must be converted from
  one of the following formats included on the CD-ROM:
  
  ARC/INFO 6.1.1 Export
  Digital Line Graph (DLG) Optional
  Drawing Exchange File (DXF)
  Map Overlay Statistical System (MOSS)
