Abstract: These metadata are specifically for the State of Minnesota,
one state in the national compilation of state geologic map databases.
The digital geologic map data was prepared by the Minnesota Geological
Survey. Subsequent editing of the spatial data by the USGS was limited
to fitting a standardized state boundary to the data, standardizing the
arc coding, reprojecting the data, and minor edits of arc or polygon
attributes to conform with the paper map.

This open-file report is one of several that present the preliminary
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 geoenvironmental
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
CONUSdocumentationMW.pdf, 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 CONUSdocumentationMW.pdf 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 Minnesota 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, CONUSdocumentationMW.pdf))

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:

C.L. Dicken obtained the digital geologic map of Minnesota from their
website:

http://www.geo.umn.edu/mgs/currentpubs.htm MGS anonymous ftp 1, folder
s-20_3ed.

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 map_label.

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

Process_Date: 20031211

Process_Step:

Process_Description:

The following attributes were exported from Filemaker as a .dbf

map_symbol1

map_symbol2

unit_link

reference_id

unit_age

rocktype1

rocktype2

The attributes were then converted to the following structures:

item name: orig_label

width: 12

output: 12

type: c

item name: sgmc_label

width: 16

Process_Date: 20040318

Process_Step:

Process_Description:

Once the .dbf was in the correct format, it was converted into a lookup
table in Arc/Info.

Then a joinitem was done using orig_label as the merge item.

Process_Date: 20040324

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: 20040421

Process_Step:

Process_Description:

Arc-code was populated using the paper 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.
