Description:
Abstract:
This open-file report presents the results of the USGS Mineral Resources
Program activity to compile a national-scale geologic map database to support
national and regional level projects, including mineral resource and geo-
environmental assessments. The only comprehensive sources of regional- and
national-scale geologic maps are state geologic maps with scales ranging from
1:100,000 to 1:1,000,000. Digital versions of these state maps form the core
of what is presented here. Because no adequate geologic map exists for the
state of Alaska, it is being compiled in regional blocks that also form part
of this national database. It is expected that this series will completed by
approximately the end of 2007. These maps and databases are being released
in blocks of states or, in the case of Alaska, as compiled blocks of
1:250,000-scale quadrangles as chapters in this series. For Alaska, formal
maps as well as databases are being published here, whereas for the
conterminous U.S. only state databases and preview graphics are presented,
because published maps for most states already exist. For Alaska these
regional compilations will form the base for compiling a new geologic map of
the state. As documented in Chapter A, standards for the conterminous U.S.
are somewhat different than those for Alaska and Hawaii.
Purpose:
A primary goal of this work is to develop geologic map datasets with
standardized structure and attribution. The database design and standards are
documented in Chapter A of this series. The intent is that contiguous databases
can be merged seamlessly and without any additional effort. In addition to a
common database structure, the conterminous U.S. state databases
(the contiguous 48 states) have been fitted to a set of standard state
boundaries so that, when states are merged, they match without slivers or
overlap. No attempt has been made to reconcile differences in mapping across
state boundaries.
Supplemental_Information:
This database consists of five major Arc/Info GIS datasets for each state;
- one: geologic map with formations,
- two: faults (where present),
- three: dikes (where present),
- four: miscellaneous line features (where present),
- five: miscellaneous point features (where present).

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The values of the attributes ROCKTYPE1 and ROCKTYPE2 were assigned based on the
information in the legends of the source maps (most of which are paper). The definitions of
these values are described in the draft document Geologic Map Classification version 6.1
(Johnson and others); available at the following website: http://geology.usgs.gov/dm )
Logical_Consistency_Report:
All internal polygons were checked for closure with vendor software and on hard copy plots.
Overshoots and undershoots have been deleted or corrected as appropriate.
Completeness_Report:
Bodies of water are classified as water, and the geologic units underlying them are not included in
this coverage.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The geologic map was digitized from compilations ranging in scale from 1:1,000,000 to 1:100,000
and is an accurate representation of the source maps. It is intended to be used at scales
ranging from 1:1,000,000 to 1:500,000. Display at significantly larger scales may produce small
errors in locations of contacts or faults relative to features contained in other data sets.
Accuracy of Montana state boundary and those arcs intersecting it: The accuracy of the state
boundary arcs is based on the 1:100000 scale original data used to produce this boundary.
(Johnson, Bruce R. and Leveritch, Beth, 1998, 1:100,000 Scale State Boundaries of the
Conterminous United States: U.S. Geological Survey, unpublished
(see metadata file: st100kmeta.txt, Chapter A))
Those internal arcs intersecting the state boundary were extended or shortened as needed to
complete polygons, possibly creating a small amount of error.

Process_Step:
Process_Description:
The purpose of this standardization is to allow all SGMC covers to be
seamlessly joined without any additional effort to form regional or national
level digital maps. Note that for Alaska, the state is being compiled as blocks
of 1:250k quadrangles that will ultimately be used to compile a new state map.
Douglas Stoeser and Ric Wilson are co-coordinators for the overall SGMC effort,
with Stoeser coordinating work on the mainland states and Wilson coordinating
work for Alaska and Hawaii.

Process_Description:
G.N. Green obtained the digital geologic map of Montana from the website:
http://pubs.usgs.gov/of/ofr-95-0691/
Re-projected the coverage into the following:
projection: Lambert Conformal Conic
units: meters
datum: NAD27
standard parallel 1: 33 0 0.000
standard parallel 2: 45 0 0.000
central meridian: -100 0 0.000
reference latitude: 0 0 0.000
false easting: 0.00000
false northing: 0.00000
All attributes were deleted except FORMATION.
(Note: Attributes associated with the generation of the coverages were not deleted.
PAT - shape, area, perimeter, coverage#, and coverage-id
AAT - shape, fnode#, tnode#, lnode#, rnode#, length, coverage#, and coverage-id)
The values from FORMATION where then calculated into a new field called orig_label.

Once the .pat file was correct, the .aat file was addressed. The following items were added
to the table:
item name: arc-code

Process_Date: 20031223
Process_Step:
Process_Description:
Arc-code was populated using the digital map source to tag the lines using the AAT line type
data dictionary.
Arc-para1 was populated when additional information was available such as upthrown side of
a fault or angle of thrusting on a fault.
Arc-para2 is a scratch field that is used mostly in Alaska.
Source was populated with code that designates the source used for the linework; typically
the paper map.
