Title: Preliminary integrated
geologic map databases for the
Geospatial_Data_Presentation_Form:
map
Online_Linkage:
http://pubs.usgs.gov/of/2005/1305/
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

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.
