Description:
Abstract:
These metadata are specifically for the State of Michigan, one
state in the national compilation of state geologic map
databases. The digital geologic map data was prepared by the
USGS. 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).

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.

Horizontal_Positional_Accuracy_Report:
Accuracy of Michigan state boundary and those arcs
intersecting it: The accuracy of the state boundary arcs is
based on the 1:100,000 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 Michigan
from the following website:
http://pubs.usgs.gov/of/of97-455/
Dicken extracted the linework for the Michigan piece of the
dataset and 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 symbol.
(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 symbol where then calculated into a new
field called orig_label.
Process_Date: 20040401
Process_Step:
Process_Description:
The relevant state outline (arcs) was removed from the
coverage and replaced with the arcs from the 1:100,000 Scale
State Boundaries of the Conterminous United States.
This allows for a seamless fit of each state to a standard
state boundary base.
Process_Date: 20040405
Process_Step:
Process_Description:
The following attributes were exported from Filemaker as a
.dbf: orig_label, map_symbol2, unit_link, reference_id,
unit_age, rocktype1, and rocktype2.
orig_label reflects the original map symbol used on the
source map
map_symbol2 reflects map-symbol1 with the addition of a
province number
unit_link is an auto generated field based on map-symbol2
and the state abbreviation (e.g. IN001) that produces a
unique identifier for each map unit
reference_id was populated with an alphanumeric code (e.g.
US001) that designates the source used for the linework and
other references used to describe the age or lithologies of
the unit.
unit_age was populated with general age assignment
rocktype1 records dominant lithology (must be >50% of
unit), using standardized data dictionary
rocktype2 records second most dominant lithology, using
standardized data dictionary
orig_label has the following field names from the source
map:
bed-geo in Illinois map_code in Indiana symbol in Michigan
symbol in Wisconsin map_label in Minnesota
The attributes were then converted using the following
structure:
item name: orig_label width: 12 output: 12 type: c
item name: sgmc_label width: 16 output: 16 type: c
item name: unit_link width: 18 output: 18 type: c
item name: source width: 6 output: 8 type: c
item name: unit_age width: 60 output: 60 type: c
item name: rocktype1 width: 40 output: 40 type: c
item name: rocktype2 width: 40 output: 40 type: c
Process_Date: 20040406
Process_Step:
Process_Description:
Once the .dbf was in the correct format with standardized
column widths and data structure, it was converted into a
lookup table (.lut) in Arc/Info. Then a joinitem was
performed to join the look-up table to the polygon attribute
table. orig_label was used as the merge item.
Process_Date: 20040406
Process_Step:
Process_Description:
Next, in preparing the uniform .aat file, 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: 20040406
Process_Step:
Process_Description:
Arc-code was populated using the paper map source to tag the
lines using the AAT line type data dictionary (see
CONUSdocumentationMW.pdf).
Arc-para1 was populated when additional information was
available such as identifying the upthrown side of a fault
or direction of thrusting on a fault. (see
CONUSdocumentationMW.pdf)
Arc-para2 is a scratch field that is used mostly in Alaska.
Source was populated with an alphanumeric code (e.g. US001)
that designates the source used for the linework.
Process_Date: 20040406
Process_Step:
Process_Description:
Once the .aat and the .pat were populated with the correct
attributes, the coverage was exported as an .e00 file
(migeol_lcc.e00).
Then it was unprojected into geographic coordinates and
exported again (migeol_dd.e00).
Process_Date: 20040423
Process_Step:
Process_Description:
The faults were extracted to generate a separate fault file.
PUT was the command used to copy the line features from the
geology line coverage into a new fault line coverage.
The data were exported as an .e00 file (mifaults_lcc.e00)
and then unprojected into geographic coordinates and
exported again (mifaults_dd.e00).
Process_Date: 20040504
Process_Step:
Process_Description:
Finally, the geology lines, geology polygons and fault line
coverages were converted into shapefiles; in both geographic
coordinates and in Lambert Conformal Conic projection.
