  Description:
    Abstract:
      This data set includes volcanoes thought to be active in the last
      10,000 years, in and near the United States.  Attributes are
      only attached to volcanoes in the United States and Canada.  The
      data are a subset of data available on the World Wide Web at:
      http://www.volcano.si.edu/gvp/volcdata/index.htm from the
      Global Volcanism Program, National Museum of Natural History,
      Smithsonian Institution.
    Purpose:
      The digital data sets of the National Atlas are used to create 
      electronic and hard copy maps that depict various aspects of 
      the nation.  The data can be used to conduct geographic 
      analysis on national and large regional scales.  The digital 
      data will provide a basis from which future revisions of the 
      atlas can be derived.
    Supplemental_Information:
      Revisions:
        1) 2/26/98 - Attributes were added to the U.S., Canada, and
        selected offshore volcanoes.
        2) 6/29/98 - Corrected ellipsoid name from WGS84 to GRS1980 and 
        changed flattening ratio.
        3) 11/13/98 - Added attribute for State FIPS code.

        The data were converted to an ARC/INFO coverage using the
        "GENERATE" command in ESRI's ARC/INFO GIS software.  Data for
        an area around the United States were clipped.  Attributes
        for the United States and Canadian volcanoes were attached.  Tics
        were added and the data were converted to Lambert Azimuthal Equal
        Area projection.
