    Description:
      Abstract:
        This data set contains boundaries and tags for major geologic units in the
        conterminous United States.  In addition to the polygons representing the
        areal extent of geologic units, it identifies boundaries of metamorphic
        provinces, major faults, calderas, impact structures, and generalized
        limits of continental glaciation.  The data depict the geology of the
        bedrock that lies at or near the land surface, but not the distribution of
        surficial materials such as soils, alluvium, and glacial deposits.

        The data are generalized from a compilation prepared for use in the
        Geologic Map of North America, to be published in hard copy by the
        Geological Society of America and released as a digital file by the U.S.
        Geological Survey.
      Purpose:
        These data have been prepared with a degree of detail appropriate for
        viewing at a scale of 1:7,500,000.  Because of the degree of
        generalization required (generalization based on compilation scale), the
        data are intended primarily for display and for regional and national
        analysis, rather than for more detailed analysis in specific areas.

        No responsibility is assumed by the U.S. Geological Survey in the use of
        these data.

      Supplemental_Information:
        The data set for the Geologic Map of the Conterminous United States
        consists of 9 data layers.  The data layers for faults and glacial limit
        lines are included in two different versions.  The data are available as
        shapefiles, Arc/INFO Export files, or graphics files (includes PDF, EPS,
        and AI formats).  The data layers are distributed and should be used
        together.  All the data layers were created as ARC/INFO coverages and
        converted to other formats for distribution purposes.  The following files
        are included:
        > Calderl075 - Outlines of major calderas and impact structures
        > Faultgl075 - Fault lines, with line decorations*
        > Faultl075 - Fault lines, without line decorations**
        > Geolgym075 - Geologic units, as polygons
        > Geotxtl075 - Graphic representation of geologic unit text*
        > Glacagl075  Generalized glacial limit lines, with line decorations*
        > Glacall075  Generalized glacial limit lines, without line decorations**
        > Impactx075 - Impact structure locations, as points
        > Metfacp075 - Areas and facies types of metamorphism, as polygons
        >
        >* these files are not 'true' Arc/INFO coverages; they are graphic
        >  representations of symbols and text used on the geologic map.   These
        >  files should be used to produce appropriately symbolized graphics.
        >  The decorations and text only appear correctly in Lambert Azimuthal
        >  Equal Area projection.
        >
        >** these files are the same as the files marked with * but do not
        >   include the line decorations.  They are the 'true' fault and glacial
        >   limit line Arc/INFO coverages.  These files should be used for data
        >   analysis.

        Although this Federal Geographic Data Committee-compliant metadata
        file is intended to document the data set in nonproprietary form, some
        Arc/INFO-specific terminology is included for clarity and expediency.

  Data_Quality_Information:
    Attribute_Accuracy:
      Attribute_Accuracy_Report:
        The line attributes were manually checked by assigning unique line
        types to the values and then plotting the data.  The plots were
        then compared to the source.

        The polygon attributes were checked by visually comparing the final
        colored plots to maps at various larger scales.
    Logical_Consistency_Report:
      Polygon and node topology are present.  All polygons are labeled and were
      tested by using the Arc/INFO command LABELERRORS.  All polygons were checked
      for closure, node errors, overshoots, undershoots, dangles and intersections
      using Arc/INFO routines. The Arc/INFO commands BUILD and CLEAN were run to
      ensure the topological consistency of the data set.
    Completeness_Report:
      This data set contains map unit boundaries and codes for the 48
      conterminous States.  Boundaries and codes are included for geologic
      units, metamorphic facies, limits of glacial advance, impact structures,
      caldera boundaries, and major faults.
    Positional_Accuracy:
      Horizontal_Positional_Accuracy:
        Horizontal_Positional_Accuracy_Report:
          The accuracy of the original data was checked by comparing the digital
          files to several data sources.  Both the line work and the polygon
          labels were checked against the source compilation.

      Process_Step:
        Process_Description:
          The geologic unit polygons (geolgym075), faults (faultl075), generalized
          glacial limit lines (glacall075), boundaries of metamorphic provinces
          (metfacp075), calderas (calderl075), and impact structures (impactx075)
          were created using the following procedures:

          Data were compiled on scale-stable clear film at various scales.  The
          lines and points were then digitized and georeferenced using the
          computer program GSMCAD, written by Van S. Williams, USGS. The program
          is available at no charge at
          <http://geology.cr.usgs.gov/maps/software.html>.  Polygons, lines, and
          point features were attributed in GSMCAD.

          Errors in polygon labeling were checked using the LABELERROR routine in
          ARCPLOT.  Node errors were checked using ARCEDIT routines.  Colored
          plots were made to make final checks of the overall coverages.

        Process_Description:
          Supplementary graphical coverages were created for the faults
          (faultgl075) and generalized glacial limit lines (glacagl075).  These
          are the same as faultl075 and glacall075 except decoration lines have
          been added for display purposes.  Another coverage was created
          containing arcs that represent text labels for the polygons
          (geotxtl075).  This is also for display purposes.

          The glacial limit attribute was changed in the file containing the
          generalized glacial limit lines with line decorations (glacagl075) and
          in the file containing generalized glacial limit lines without line
          decorations (glacall075).  Wisconsin Glacial Limit Line was changed to
          Wisconsin Glacial Limit and Pre-Wisconsin Glacial Limit Line was
          changed to Pre-Wisconsin Glacial Limit.
