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 Colorado 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_Date: 2003 - 2004

Process_Step:

Process_Description:

G.N. Green obtained the digital geologic map of Colorado from the
website:

http://pubs.usgs.gov/of/ofr-92-0507/

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: 0.000

false northing: 0.000

All attributes were deleted except NAME.

(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 NAME where then calculated into a new field called
orig_label.

Process_Date: 20031215

Process_Step:

Process_Description:

The following attributes were exported from Filemaker as a comma
delimited file

map_symbol1

map_symbol2

unit_link

reference_id

unit_age

rocktype1

rocktype2

The attributes were then loaded into INFO with the following structures:

item name: orig_label

width: 12

output: 12

type: c

item name: sgmc_label

width: 16

output: 16

Process_Description:

Once the .csv was loaded, it was joined in Arc/Info with the joinitem
command.

orig_label as the related item.

Process_Date: 2004818

Process_Step:

Process_Description:

Once the .pat file was correct, the .aat file was addressed. The
following items were added

to the table:

item name: arc-code

width: 3

output: 3

type: i

item name: arc-para1

width: 3

output: 3

type: i

item name: arc-para2

width: 3

output: 3

type: i

item name: source

width: 6

output: 8

type: c

Process_Date: 20040102

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.
