  Description:

    Abstract: These digital maps are a reformulation of previously published maps, primarily maps of states. The reformulation gives all the maps the same structure and format, allowing them to be combined into regional maps. The associated data tables have information about age and lithology of the map units, also in a standard format.

    Purpose: Provide digital maps and databases that, because of their common structure and format, allow creation of regional maps that depict age and lithology of map units.

    Supplemental_Information: The data is provided in decimal degrees and in Lambert Conformal Conic projection. The data is provided in both coverage and shapefile format, and includes supplemental attribute tables. No attempt was made to reconcile differences in mapping across state boundaries.

Data_Quality_Information:

  Attribute_Accuracy:

    Attribute_Accuracy_Report: Map unit designations were completely renovated and modernized by Art Bookstrom, using the paper map legend and geologic literature.

  Logical_Consistency_Report: All internal polygons were checked for closure. Overshoots and undershoots have been deleted or corrected as appropriate.

  Completeness_Report: The dataset contains all the map unit polygons portrayed on the original map, although many of their designations have changed. The dataset contains all the faults that were portrayed on the original printed map. Bodies of water are classified as water and geologic units underlying them are not portrayed.

  Positional_Accuracy:

    Horizontal_Positional_Accuracy:

      Horizontal_Positional_Accuracy_Report: The geologic map was digitized from a map compiled at 1:500,000, and is an accurate representation of the source map. It is intended to be used at scales equal to or smaller than 1:500,000. Display at significantly larger scales may produce error in location of contacts or faults relative to features contained in other data sets. The state boundary arcs are based on the 1:100,000 scale USGS topographic map series digital line graphs.

      Source_Contribution: Provided linework for state boundaries

    Process_Step:

      Process_Description: Dataset copied from USGS website.

      Process_Date: 2005

    Process_Step:

      Process_Description: Adjusted the perimeter of the coverage to match a reference dataset of state boundaries derived from 1:100,000 scale digital line graphs. This allows the map to be used together with adjoining state maps referenced to the same boundary data. The state boundaries have a source of US001 in the AAT.

      Process_Date: 2005

    Process_Step:

      Process_Description: Following standard items were added to AAT: ARC-CODE, ARC-PARA1, ARC-PARA2 (last two not used). ARC-CODE was populated using the line codes in the original coverage and inspection of the printed map. Original items in AAT were deleted.

      Process_Date: 2006

    Process_Step:

      Process_Description: The original map had no unit names or descriptions. Art Bookstrom compiled this information into the accompanying database tables, in effect, creating a new legend. About 4,000 of nearly 11,000 polygons had their designations changed to conform to this new legend, and many new units were created. This information is stored in the SGMC_LABEL field of the PAT. The individual changes are documented in the SOURCE field of the PAT. The key to what those changes were is in an accompanying table, IDGEOL_LCC.SOURCE, which can be joined to the PAT using SOURCE as the key field.

      Process_Date: 2006

    Process_Step:

      Process_Description: Following standard items were added to PAT: ORIG_LABEL, SGMC_LABEL, UNIT_LINK, SOURCE, UNIT_AGE, ROCKTYPE1, AND ROCKTYPE2. ORIG_LABEL was populated from the original coverage item, and the other information was obtained from the accompanying database tables (ORunits, ORage, ORlith). Unneeded items were then deleted from the PAT.
