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.

Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government

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.

Attribute_Label: Text

Attribute_Definition:

The value recognized by the program GSMCAD and used to create the special font for geologic symbols, e.g. %217 represents the geologic symbol for mesozoic. Because standard fonts available in ARC/INFO do not have the special symbols used for geologic time periods, the symbols were created in GSMCAD and exported as arcs.
