GENERAL
DESCRIPTION OF THE GIS DATABASE:
SURFACE MINES WITHIN THE
STATE OF GEORGIA
PERMITTED THROUGH 31 DECEMBER 1999
1.0 Identification / Project Background
This database contains locations and associated information
for 605 surface mines within the state of Georgia that were permitted by
the Georgia Environmental Protection Division (EPD).
As a convenience to the reader of Part A, a page size statewide
map of the mines database is included in Appendix B - Figure 1. The 1999
data were compiled with data from 5 previously completed mine databases,
which had been developed for most of the river basins in Georgia. As shown
in Table One, Appendix B, the database includes the facility's permit number
and name, the county name, the latitude and longitude coordinates (in degrees,
minutes, and seconds) for either the facility's weigh station, entrance,
or some other location, the type of mine, the materials extracted, the major
river basin name and 8-digit U.S. Geological Survey hydrologic unit code
(HUC) for the associated river basin, and the code describing the site occupied
(S_O) at the facility while collecting GPS data. The facilities' GPS locations
were obtained by Geologic Survey Branch (GSB) personnel utilizing a Trimble
Navigation global positioning satellite (GPS) receiver for data collection
while occupying the facility's weigh station or facility's entrance. An
alternate location was selected, if either the weigh station or entrance
were inaccessible.
The uncorrected positional data was corrected for various
errors inherent in GPS positional data by processing with differential correction
software and the corrected coordinates were entered into the GIS database.
The manufacturer's specification for the Trimble Navigation GPS receiver
describes a horizontal positional accuracy of +/- 5 meters after differential
corrections are applied.
The database is being published at a scale of 1:24,000 and
is current through 31 December 1999.
2.0 Data Quality
This section contains information about the lineage, positional
accuracy, attribute accuracy, logical consistency, and completeness of the
database.
2.1 Attribute Accuracy
Many of the attributes for this database were obtained from
EPD's Land Protection Branch (LPB) and originated from its mine-permit files.
Attributes selected for use in the GIS database are the county name, mine
type, materials mined, the facility's permit number, and name. Attributes
were reviewed for accuracy by comparison with source computer printouts and
corrections made when errors were discovered
. Prior to releasing the GIS database
a representative of the LPB makes a final review of the data; see the appendix
A, signature sheet following the section Part A.
The surface mine's latitude-longitude coordinates were determined
in the field utilizing a Trimble Navigation GPS receiver for data collection
while occupying either the facility's weigh station or entrance. If either
of these two locations were inaccessible then an alternate location was selected.
The uncorrected positional data was corrected for various errors inherent
in GPS positional data by processing with differential correction software.
The corrected coordinates were entered into this GIS database. The manufacturer's
specification for the Trimble Navigation GPS receiver states a horizontal
positional accuracy of +/- 5 meters after differential corrections are applied.
The facility locations was electronically overlaid on a
1:100,000 scale county boundary database, and a 1:250,000 scale U.S. Geological
Survey river basin database. The county name, the major river basin name,
and the HUC for the river basin where the facility is located were added
into the GIS database by utilizing the database overlay capability of the
GIS software (ARC/INFO version 8.0.2).
The database is being published at a scale of 1:24,000.
2.2 Logical Consistency
The facility locations were
overlaid with an existing county boundary database to check the spatial
accuracy; to see if the facilities locations are within the correct county.
Attributes in the database were reviewed for accuracy by comparing with
source information and corrections made when errors were discovered.
2.3 Completeness
This database contains 605 surface mines within the state
of Georgia that were permitted by EPD. The database is current through 31
December 1999.
2.4 Positional Accuracy
Each facility's latitude-longitude coordinates were determined
in the field by GSB personnel utilizing a Trimble Navigation GPS receiver
for data collection while occupying either the facility's weigh station,
entrance, or an alternate location. The uncorrected positional data collected
by the receiver were corrected for various errors inherent in GPS positional
data by processing with differential correction software. The corrected
coordinates were entered into the GIS database. The manufacturer's specifications
for the Trimble Navigation GPS receiver state a horizontal positional accuracy
of +/- 5 meters after differential corrections have been applied. The database
is being published at a scale of 1:24,000.
2.5 Lineage
The source information for this statewide database is a
combination of 5 previously mine GIS databases whose extent were defined
by river basin, and an up-to-data (as of 31 December 1999) computer printout
of the EPD's Land Protection Branch surface mine database, which containing
associated data for each facility. Data from the above sources were appended
to create this current statewide GIS database. The reader is referred to
the documentation reports in the Technical files at GGS for the previously
developed databases, which are as follows:
DR96-29 -
- Surface Mines Within the Chattahoochee-Flint River Basins in Georgia,
Permitted Through April, 1994
DR97-05 - -
Surface Mines Within the Coosa-Tallapoosa and Oconee River Basins in Georgia,
Permitted Through July 1997
DR98-17 - -
Surface Mines Within the Savannah-Ogeechee River Basins in Georgia, Permitted
Through January 1998
DR98-27 - -
Surface Mines Within the Satilla, St. Marys, Suwannee, and Ochlocknee River
Basins in Georgia, Permitted Through December 1998
DR99-04 - -
Surface Mines Within the Ocmulgee River Basin in Georgia, Permitted Through
December 1998
GSB personnel copied for each facility from the LPB computer
printout, the county name, the facility's permit number and name, address,
mine type, and material mined; manually entered the data onto each facility's
GPS field data sheet. These field data sheets were taken to the facility,
where a GPS file name, date, time, location occupied, an uncorrected latitude-longitude
coordinate (read from the GPS receiver), and other miscellaneous field notes
as necessary were added onto the data sheet. Data from the field data sheets
was typed into a Quattro Pro spreadsheet and then field data sheets were
filed for future reference.
During GPS processing the GPS data receiver files were downloaded
in the office into a personal computer, and differential correction post-processing
was performed on the data files utilizing Trimble Navigation's PATHFINDER
OFFICE version 2.01 software. Base station data for post-
processing differential correction was obtained from the
US Department of Agriculture, Forest Service Trimble base station located
on top of the Southern Region Office at 1720 Peachtree Rd., Atlanta Georgia.
The base station data is available and downloadable via the Internet
http://www.fs.fed.us/database/gps/atlanta.htm
. The differentially corrected latitude-longitude coordinate was written
onto a copy of the field data sheet and compared to the uncorrected GPS coordinate
collected in the field. In addition, the entries made in Quattro Pro spreadsheet
are compared to the GPS field sheets and corrections made if needed and then
the field sheets were filed by county for future reference.
The information from the
five previously developed surface mine databases, and information for the
surface mines, which are not included in the five databases, but were permitted
as of 31 December 1999, were added together to make a master dBase file for
the 1999 surface mine data.
This master dBase file was transferred to a NT workstation
where the master file was processed in ARC/INFO (version 8.0.2) software
by an EPA written program, dbf2cover,
to create a geographic database, with each facility represented digitally
as a point.
Then the mine facility data were electronically overlaid
on a 1:100,000 scale county boundary database, and a 1:250,000 scale U.S.
Geological Survey river basin database. The correct county name, river basin
name, and HUC were then automatically assigned to each facility location
by the Arc/info software, based on the corrected GPS latitude-longitude coordinate
of the facility.
3.0 Spatial Data Organization Information
This database contains the locations for the 605 permitted
surface mines located within the state of Georgia. Each facility is represented
digitally as an individual point.
4.0 Spatial Reference Information
This database is stored in the Albers Conic Equal Area projection
with units in meters. Further information on the specific parameters used
can be found in Part B, Section 4.0.
5.0 Entity and Attribute Information
Each data record in the GIS database has ten pertain attributes
detailing pertinent information about the surface mine. Information includes
the facility's permit number, its name, mine type, materials mined, the county
name, latitude and longitude coordinates (in degrees, minutes, and seconds)
for the facility's weigh station, facility entrance or other location, the
major river basin where facility is located, the U.S. Geological Survey 8-digit
HUC associated with the major river basin, and a code describing the site
occupied at the facility while collecting GPS data (e.g. weigh station, entrance,
or other).
6.0 Distribution Information
This database is maintained by the Geologic Survey Branch,
in their Technical Files, referenced as Surface Mines Within Georgia, Permitted
Through 31 December 1999.
7.0 Metadata Reference Information
The metadata is incorporated within this publication, DOCUMENTATION
REPORT 00-45. Part B, the Technical Section of this publication, meets the
"Content Standards for Digital Geospatial Metadata" as published
by the Federal Geographic Data Committee in 1994.

1.21 Abstract:
This database contains
locations and associated information for 605 surface mines within the state
of Georgia permitted by the Georgia Environmental Protection Division (EPD).
A page size statewide map of the mines
database is included in Appendix B - Figure 1. The 1999 data were compiled
with data from 5 previously completed mine databases, which had been developed
for most of the river basins in Georgia. As shown in Table One, Appendix
B, the database includes the facility's
permit number and name, the county name, the latitude and longitude coordinates
(in degrees, minutes, and seconds) for either the facility's weigh station,
entrance, or other location, the mine type, the materials extracted, the
major river basin name and 8-digit U.S. Geological Survey hydrologic unit
code (HUC) for the associated river basin, and the code describing the site
occupied (S_O) at the facility while collecting GPS data. Geologic Survey
Branch (GSB) personnel utilizing a Trimble Navigation global positioning
satellite (GPS) receiver for data collection while occupying either the weight
station or mine entrance obtained the locations for the facilities. If either
of the locations were inaccessible, then an alternate location is chosen.
The uncorrected positional
data were corrected for various errors inherent in GPS positional data by
processing with differential correction software. The corrected coordinates
were entered into the GIS database. The manufacturer's specification for
the Trimble Navigation GPS receiver, describes a horizontal positional accuracy
of +/- 5 meters after differential corrections are applied.
The database is being
published at a scale of 1:24,000 and is current through 31 December 1999

1.8 Use Constraints:
The Georgia Geologic
Survey Branch should be acknowledged as the data source in products derived
from these data.
This data set is
not designed for use as a primary regulatory tool in permitting or siting
decisions, but may be used as a reference source. This is public information
and may be interpreted by organizations, agencies, units of government, or
others based on needs; however, they are responsible for the appropriate
application. Federal, State, local regulatory bodies, private individuals
or organizations are not to reassign to the Georgia Geologic Survey Branch
any authority for the decisions that they make.
This data set is not
intended for map scales greater than 1:24000. Photographic or digital enlargement
of these maps to scales greater than at which they were originally mapped
can cause misinterpretation of the data. The use of these data does not
eliminate the need for onsite sampling, testing, and detailed study of specific

2.5.2a Process Information:
Procedures used to create or automate data:
The source information for this statewide database is a combination of 5
previously mine GIS databases whose extent were defined by river basin, and
an up-to-data (as of 31 December 1999) computer printout of the EPD's Land
Protection Branch surface mine database, which containing associated data
for each facility. Data from the above sources were appended to create this
current statewide GIS database. The reader is referred to the documentation
reports in the Technical files at GGS for the previously developed databases,
which are as follows:
DR96-29
- - Surface Mines Within the Chattahoochee-Flint River Basins in Georgia,
Permitted Through April, 1994
DR97-05
- - Surface Mines Within the Coosa-Tallapoosa and Oconee River Basins in
Georgia, Permitted Through July 1997
DR98-17

Surface Mines Within the Savannah-Ogeechee River Basins in Georgia, Permitted

Basins in Georgia, Permitted Through December 1998
DR99-04
- -
Surface Mines Within the Ocmulgee River Basin in Georgia, Permitted Through
December 1998
GSB personnel copied
from the LPB computer printout for each facility, the county name, the facility's
permit number and name, address, mine type, and material mined; manually
entered the data onto each facility's GPS field data sheet. These field
data sheets were taken to the facility, where a GPS file name, date, time,
location occupied, an uncorrected latitude-longitude coordinate (read from
the GPS receiver), and other miscellaneous field notes as necessary were
added onto the data sheet. Data from the field data sheets was typed into
a Quattro Pro spreadsheet and then field data sheets were filed for future
reference.
During GPS processing
the GPS data receiver files were downloaded in the office into a personal
computer, and differential correction post-processing was performed on the
data files utilizing Trimble Navigation's PATHFINDER OFFICE version 2.01
software. GPS base station data for
differentially post-processing were obtained from
the US Department of Agriculture, Forest
Service Trimble base station, located on top of the Southern Region Office
at 1720 Peachtree Rd., Atlanta Georgia. The base
station data is available and downloadable via the Internet:
http://www.fs.fed.us/database/gps/atlanta.htm
.
GPS receiver data
were differentially corrected using the NAD27 geodetic datum and output into
an ASCII file. The differentially corrected latitude-longitude coordinate
were written onto a copy of the field data sheet and compared to the uncorrected
coordinate collected in the field.
In
addition, the entries made in Quattro Pro spreadsheet are compared to the
GPS field sheets and corrections made if needed and then the field sheets
were filed by county for future reference.
The information from the five previously developed surface mine databases,
and information for the surface mines, which are not included in the five
databases, but were permitted as of 31 December 1999, were added together
to make a master dBase file for the 1999 surface mine data. This master
dBase file was transferred to a NT workstation where the master file was
processed in ARC/INFO (version 8.0.2) software by the program DBF2COVER,
(dBase file to GIS Coverage), written by the US Environmental Protection
Agency (EPA),
http://www.epa.gov/r10earth/dbf2infp.htm
. This program converts
a dBase file directly into a GIS database/coverage.
Then the facility
data were electronically overlaid on a 1:100,000 scale county boundary database,
USGS CO, and a 1:250,000 scale U.S. Geological Survey river basin database,
USGS HUC. The correct county name, river basin name, and HUC were then automatically
assigned to each facility location's site by ARC/INFO software
version 8.0.2, based on the corrected GPS
latitude-longitude coordinate of the facility.
