OVERVIEW
A documentation
report follows the "Content Standards for Digital Geospatial Metadata"
(Standards) developed by the Federal Geographic Data Committee (FGDC), published
June 8, 1994. As a convenience, Part A and B employ the outline/headings
contained in the Standards. Part A and B are printed on paper and Part C
is composed of digital products. Part B meets the technical requirements
of the Standards.
This document is a three-part documentation report for a
Geographic Information System (GIS) database developed, with Arc/Info software,
by the Geologic Survey Branch, Environmental Protection Division of the Georgia
Department of Natural Resources. Part A is intended as a general purpose
summary of the database. Part B is a more technical section included primarily
for the benefit of GIS processors. Part C contains the digital products;
the database and its associated documentation, which includes a copy of this
publication.
The digital documentation in Part C contains two copies
of this publication. One digital copy is stored as an ASCII file, DR0015.TXT.
The other copy is in rich text format, DR0015.RTF. The digital database in
Part C consists of an Arc/Info Export file DR0015.E00. Copy the Arc/Info
Export file into a directory where you want it and then run the Arc/Info
Import command. See Part C of this document for a complete list of the diskette's
contents and for data file size.
The digital files are written to one 1.44 MB High Density
data diskette. A directory of the files and a short explanation is contained
in the ASCII file READ.ME on the data diskette.
This database was developed to satisfy specific project
purposes. Users are advised to read the entire Documentation Report and to
evaluate the suitability and limitations of the database for the user's purposes.
This document describes the industrial surface-water intake locations statewide
through December 1999 and supercedes previous industrial surface-water intake
documentation reports for individual river basins.

a popular GIS software, used by the GSB.
ASCII: abbreviation for "American Standard Code
for Information Interchange". A set of codes for representing alphanumeric
information in a format which any computer can read.
attribute: a characteristic of a geographic feature.
For example, if the geographic feature is a river, then the attributes of
the river are the river name, the flow rate, the chemical history, etc.
attribute accuracy: a measure of how well the reported
characteristics actually match the real-world characteristics of a geographic
feature.
Compact Disk Read Only Memory (CDROM): an optical
medium which can store 650 Mb of information.
completeness: a description of the relation between
the items represented in the database and the real world. For example, if
a database contains water wells in Georgia, does it contain all the water
wells in Georgia, or a defined sub-set of wells? If the database contains
a defined sub-set of wells, does it contain every well in Georgia that meets
the definition by which the sub-set was chosen?
Content Standards for Digital Geospatial Metadata:
a standard developed by the FGDC which specifies the information content
of metadata for a set of digital geospatial data.

PART A - GENERAL DESCRIPTION
OF THE GIS DATABASE:
INDUSTRIAL SURFACE-WATER INTAKES WITHIN THE STATE OF GEORGIA PERMITTED
THROUGH DECEMBER 1999
1.0 Identification / Project
Background
This database contains locations
and associated information for 107 EPD permitted industrial surface-water
intakes within the state of Georgia, where the data is derived from new collection
plus the 6 river basin based databases cited in full in Part B. Information
in the database includes the permittee's name, permit number, county location,
latitude and longitude coordinates (in degrees, minutes, seconds) for the
facility's raw water intake, or the river bank when the raw water intake
is located in the middle of the stream/lake, or other location if either
of the previous are inaccessible , major river basin where site is located,
an 8 digit U.S. Geological Survey hydrologic unit code for the associated
river basin, the name of the water body which supplies the water, and a code
describing the location occupied at the facility while collecting GPS data.
The locations were obtained by Geologic Survey Branch (GSB) personnel utilizing
a Trimble Navigation GPS Pathfinder Basic Plus global positioning satellite
(GPS) receiver for data collection while occupying either the facility's
raw water intake, or the river bank when the raw water intake is located
in the middle of the stream/lake, or other location if either of the previous
are inaccessible. The uncorrected locational data were corrected for various
errors inherent in GPS locational data by processing with differential correction
software and were entered into a GIS database.
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
The information for many of the
attributes for this database (see Section 5.0, Part B) was obtained from
computer printouts supplied by EPD's Watershed Protection Branch. Information
contained in the Watershed Protection Branch's computer database was
copied from surface-water intake permit application files and was verified
by the Watershed Protection Branch personnel who review surface-water
intake permit applications.
Surface-water intake facility latitude-longitude coordinates
were determined in the field utilizing Trimble Navigation GPS Pathfinder
Basic Plus global positioning satellite (GPS) receivers for data collection
while occupying either the facility's raw water intake, or the river bank
when the raw water intake is located in the middle of the stream/lake, or
other location if either of the previous locations are inaccessible. The
uncorrected locational data were corrected for various errors inherent in
GPS locational data by processing with differential correction software and
were entered into a GIS database.
The manufacturer's specifications for the Trimble Navigation
GPS Pathfinder Basic Plus receiver state a horizontal positional accuracy
of +/- 5 meters. The database is being published at a scale of 1:24,000.
The county name, the major river basin name, and the hydrologic
unit code for the river basin where the facility is located were added to
the database by utilizing a database overlay capability of the GIS software
(ARC/INFO version 7.1). The facility location was 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 hydrologic
unit code were then automatically assigned to each facility location point
by the software, based on the latitude-longitude coordinate of the facility.
2.2 Logical Consistency
Facility locations were overlaid with an existing county
political boundary database to ensure spatial accuracy, and locational corrections
were made when errors were discovered. Attributes were reviewed for accuracy
by comparison with source tables and corrections made when errors were discovered.
In a few cases when errors could not be resolved, the facility was revisited.
2.3 Completeness
This database contains the EPD permitted
industrial surface-water intakes located within the state of Georgia. EPD
requires a water-withdrawal permit for any industrial facility which withdraws
100,000 gallons per day or more. This database does not contain facilities
which withdraw less than 100,000 gallons per day. The database is current
through December 1999.
2.4 Positional Accuracy
Surface-water intake facility latitude-longitude
coordinates were determined in the field by GSB personnel utilizing a Trimble
Navigation GPS Pathfinder Basic Plus global positioning satellite (GPS) receiver
for data collection while occupying the raw water intake, or the river bank
when the raw water intake is located in the middle of the stream/lake, or
other location if either of the previous are inaccessible. The uncorrected
locational data were corrected for various errors inherent in GPS locational
data by processing with differential correction software and were entered
into a GIS database. The manufacturer's specifications for the Trimble Navigation
GPS Pathfinder Basic Plus receiver state a horizontal positional accuracy
of +/- 5 meters. The database is being published at a scale of 1:24,000.
2.5 Lineage
The source documents for this database
were printouts of a computer database containing latitude-longitude coordinates
and associated data for permitted industrial surface-water intakes as supplied
by EPD's Watershed Protection Branch. For each facility, a facility
name, permit number, address, county, river basin, source water-body name,
and facility latitude-longitude coordinates were copied by GSB personnel
from the source tables and manually entered onto field data sheets. These
field data sheets were taken to the facility, where a GPS file name, date,
time, location occupied, an uncorrected latitude-longitude coordinate (from
the GPS receiver), and other field notes as necessary were added to the data
sheet. GPS data files were downloaded in the office from the GPS receivers
to a personal computer, and differential correction post-processing was done
utilizing Trimble Navigation's PFINDER software. Base station data for differential
post-processing were obtained from the US Department of Agriculture, Forest
Service Trimble base station using web access. The differentially corrected
latitude-longitude coordinate was written on the field data sheet and compared
to the uncorrected coordinate collected in the field. Data from the field
data sheets were typed into a Microsoft Excel spreadsheet. Field data sheets
were filed by county for future reference. Spreadsheet data were saved as
a comma delimited ASCII file and transferred to a DG/UX workstation via file
transfer protocol (ftp) procedures. Latitude-longitude coordinates were processed
to create a geographic database, utilizing ARC/INFO version 7.1 and ARC/INFO
8.01 GIS software, with each facility represented digitally as an entity
point.
The above
procedure was performed for each basin resulting in a separate coverage in
each case. The final step required to produce a single statewide coverage
was to use the Arc/Info command Append to join the separate point coverages
together.
3.0 Spatial Data Organization
Information
This database contains the
locations for permitted industrial surface-water intakes located within the
state of Georgia. The facilities are represented digitally as 107 entity
points.
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 point in the database
has nine (9) attributes detailing pertinent information about the surface-water
intake. Information includes the permittee's name, permit number, county
location, latitude and longitude coordinates (in degrees, minutes, seconds)
for the facility's raw water intake, or the river bank when the raw water
intake is located in the middle of the stream/lake, or other location if
either of the previous is inaccessible, major river basin where site is located,
an 8 digit U.S. Geological Survey hydrologic unit code for the associated
river basin, source water body name, and a code describing the location occupied
at the facility while collecting GPS data (eg. raw water intake, bank, other).
6.0 Distribution Information
This database is maintained
by the Georgia Geologic Survey Branch, in their Technical Files, referenced
as Documentation Report DR0015, Industrial Surface-Water Intakes within the
State of Georgia, Permitted through December 1999.
7.0 Metadata Reference Information
The metadata is incorporated
within this publication, DOCUMENTATION REPORT 00-15. 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.

Attribute_Accuracy_Report:
The information for many of the
attributes for this database (see Entity and Attribute Section, Part B) were
obtained from computer printouts supplied by EPD's Watershed
Protection Branch. Information contained in the Watershed
Protection Branch's computer database was copied from Surface_water
intake permit application files and was verified by the Watershed
Protection Branch personnel who review Surface_water intake
permit applications.
Surface_water intake facility latitude_longitude coordinates
were determined in the field utilizing Trimble Navigation GPS Pathfinder
Basic Plus global positioning satellite (GPS) receivers for data collection
while occupying either the facility's raw water intake, or the river bank
when the raw water intake is located in the middle of the stream/lake, or
other location if either of the previous were inaccessible. The uncorrected
positional data were corrected for various errors inherent in GPS positional
data by processing with differential correction software and were entered
into a GIS database.
The manufacturer's specifications for the Trimble Navigation
GPS Pathfinder Basic Plus receiver state a horizontal positional accuracy
of +/_ 5 meters. The database is being published at a scale of 1:24,000.
The county name, the major river basin name, and the hydrologic
unit code for the river basin where the facility is located were added to
the database by utilizing a database overlay capability of the GIS software
(ARC/INFO version 7.0). The facility location was overlaid on a 1:100,000
scale county boundary database, and a 1:500,000 scale U.S. Geological Survey
river basin database. The correct county name, river basin name, and hydrologic
unit code were then automatically assigned to each facility location point
by the software, based on the latitude_longitude coordinate of the facility.
Logical_Consistency_Report:
Point features present. Facility
locations were overlaid with an existing county political boundary database
to ensure spatial accuracy, and positional corrections were made when errors
were discovered. Attributes were reviewed for accuracy by comparison with
source tables and corrections made when errors were discovered. In a few
cases when errors could not be resolved, the facility was revisited.
Completeness_Report:
This database covers the state of
Georgia. The database contains the EPD permitted industrial surface-water
intakes located within the state of Georgia. EPD requires a water-withdrawal
permit for any industrial facility which withdraws 100,000 gallons per day
or more. This database does not contain facilities which withdraw less than
100,000 gallons per day and which are not permitted by EPD. The database
is current through December 1999.

GSB personnel collected the GPS
positional information, compiled the information from the WRMB computer printout,
processed the data into an Arc/Info GIS database, and documented the database
according to GSB standards.
Process_Step:
Process_Description:
The following procedure was carried
out in order to process five (5) industrial surface water sites in the first
step in the production of the complete statewide coverage from separate basin
coverages of the intake points. These 5 points were an addendum.
The source documents for this database were printouts of
computer data files supplied by the Georgia Environmental Protection Division's
Watershed Protection Branch. This computer data file listed the industrial
surface_water intakes sites in the State of Georgia, which includes the facility
name, permit number, intake number, water body source, county name, address,
and contact person for the facility. Geologic Survey Branch's field personnel
visited each facility with a Trimble Basic_Plus GPS receiver, with instructions
to occupy the facility's raw water intake, or the river bank when the raw
water intake is located in the middle of the stream/lake, or other location
if either of the previous is inaccessible. The field personnel took notes
at each facility, including the GPS file name, date, time, county location,
facility's name and permit number, the river basin, the actual site occupied
during the GPS location file collection, and the uncorrected latitude_longitude
coordinate read from the GPS receiver. The files in the GPS receiver were
downloaded in the office directly into a personal computer. Trimble's PATHFINDER
OFFICE software, version 2.01 for Windows, was utilized for differential
correction post_processing. Base station data for post_processing differential
correction were obtained from the US Department of Agriculture, Forest Service
Trimble base station using web access.
GPS data were differentially corrected using the NAD27 geodetic
datum and output into an ASCII file. The differentially corrected latitude_longitude
coordinate was written on the field data sheet and compared to the uncorrected
GPS coordinate collected in the field. Data from the field data sheets were
typed into a Microsoft Excel spreadsheet. Field data sheets were filed by
county for future reference. Spreadsheet data were saved as a dBase file
and this dBase file was processed in ARC/INFO (version 8.01) software by
the program DBF2COVER, (dBase file to GIS Coverage) written by the US Environmental
Protection Agency (EPA), This program converts a dBase file directly into
a GIS database/coverage. The county name, the major river basin name, and
the hydrologic unit code for the river basin where the facility is located
were added to the GIS database by utilizing a database overlay capability
of the GIS software ARC/INFO (version 8.01). The facility location was 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 hydrologic unit code were then automatically assigned to each facility
location's site by ARC/INFO software, based on the corrected GPS latitude_longitude
coordinate of the facility.

Process_Step:
Process_Description:
The info PAT files of each coverage
(both referenced basin coverages and the 5 point extra coverage whose processing
is described above) are structured as described in the attribute information
below. This was accomplished by a process of exporting each info file to
a comma delimited text file in which the fields are ordered in consistent
manner according to the required final structure. The comma delimited datafiles
were then imported back into an info files of consistent structure using
the info command "add from".
The resulting info files were then converted back into coverages
with consistent PAT structures using the EPA written utility info2cover.
A single statewide coverage was created using the Arc/Info
Append command to join the separate point coverages (referenced above in
the Source Citations, and the new 5 point coverage) producing an output coverage
called isw.
This was accomplished using the following command:
Append isw point all
