    Description:
      Abstract:
        These data are a digital version of U.S. Geological Survey Professional
        Paper 1183, Landslide Overview Map of the Conterminous United States.  The
        map and digital data delineate areas in the conterminous United States
        where large numbers of landslides have occurred and areas which are
        susceptible to landsliding.  Because the data are highly generalized,
        owing to the small scale and the scarcity of precise landslide
        information for much of the country, they are unsuitable for local
        planning or actual site selection.  This National Atlas map layer was
        previously distributed as Digital Representation of the Landslide
        Overview Map of the Conterminous United States.
      Purpose:
        These data are intended for geographic display and analysis at the
        national level, and for large regional areas.  The data should be
        displayed and analyzed at scales appropriate for 1:4,000,000-scale data.
        No responsibility is assumed by the U.S. Geological Survey in the use of
        these data.
      Supplemental_Information:
        The purpose of this map layer is to give the user a general indication of
        areas that may be susceptible to landsliding.  It is not suitable for
        local planning or site selection.

        More information on the USGS National Landslides Hazards Program is
        available at <http://landslides.usgs.gov/>.

      Process_Step:
        Process_Description:
          Polygons were closed along the coastline using the National Atlas
          coastline file.  Minor revisions were made to spatial and attribute
          information in consultation with one of the original authors (D.J.
          Varnes).
        Source_Used_Citation_Abbreviation: Coastlines
        Process_Date: 2000
      Process_Step:
        Process_Description:
          Sliver polygons along State lines were eliminated by merging the
          polygons with the appropriate larger polygon to which they belonged.
          Adjacent polygons with the same descriptor of landslide incidence and
          susceptibility (inc_sus) were merged.  Interior State lines were deleted
          and the attribution was checked.  A value of 'no-data' was applied to
          water areas such as Puget Sound and the Great Lakes.

      Process_Step:
        Process_Description:
          Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands were removed
