Title:: Integrated Geologic Map Databases for the United States: Alabama, Florida, Georgia, Mississippi, North Carolina, and South Carolina
Abstract:: This 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 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 Chapter A, standards for the conterminous U.S. are somewhat different than those for Alaska and Hawaii.
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).

Why was the data set created?

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.

How was the data set created?

From what previous works were the data drawn?

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.

Date: 18-Nov-2004 (process 2 of 11)
C.L. Dicken obtained the digital geologic map of South Carolina from the following website - <http://pubs.usgs.gov/of/of01-298/>.
The coverage was re-projected 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_code .
(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_code where then calculated into a new field called orig_label.

Date: 30-Nov-2004 (process 3 of 11)
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.
Water polygons that were generated from the use of this outline are tagged with a source code of SC201.

Date: 08-Dec-2004 (process 4 of 11)
The eastern section of the state (mostly the coastline) was obtained from an unpublished map that Wayne Newell (USGS) compiled. Source is SC101. Arcs were added to line coverage.

Date: 18-Nov-2004 (process 5 of 11)
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
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

Date: 08-Dec-2004 (process 6 of 11)
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.

Date: 08-Dec-2004 (process 7 of 11)
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

Date: 08-Dec-2004 (process 8 of 11)
Arc-code was populated using the paper map source to tag the lines using the AAT line type data dictionary (see Chapter A in this series).
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 Chapter A)
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.

Date: 12-Apr-2005 (process 9 of 11)
Once the .aat and the .pat were populated with the correct attributes, the coverage was exported as an .e00 file (scgeol_lcc.e00).
Then it was unprojected into geographic coordinates and exported again (scgeol_dd.e00).

Date: 12-Apr-2005 (process 10 of 11)
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 scfaults_lcc.e00 and then unprojected into geographic coordinates and exported again (scfaults_dd.e00).

Date: 12-Apr-2005 (process 11 of 11)
Finally, the geology lines, geology polygons and fault line coverages were converted into shapefiles; in both geographic coordinates and in Lambert Conformal Conic projection.
What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

How well have the observations been checked?
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>
How accurate are the geographic locations?
Accuracy of South Carolina 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, 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.
How accurate are the heights or depths?
Where are the gaps in the data? What is missing?
Bodies of water are classified as water, and the geologic units underlying them are not included in this coverage.
How consistent are the relationships among the observations, including topology?
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.

How can someone get a copy of the data set?
