GENERAL DESCRIPTION OF THE GIS DATABASE:
LAND APPLICATION SITES (LAS) WITHIN GEORGIA,
PERMITTED THROUGH 31 December 1999
1.0 Identification / Project Background
This GIS database contains locations and associated information for 211 land application sites (LAS) 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 LAS database is included in Appendix B - Figure 1. The data were updated and compiled with data from 6 previously completed LAS databases which had been developed for most of the river basins in Georgia. As shown in Table One, Appendix B, the database includes the permit number, facility's name or permit-holder's name, the LAS type (municipal, industrial, or private), the county name, the longitude and latitude coordinates (in degrees, minutes, and seconds) for the facility's intake pump at the discharge pond, spray-field, or alternate location, the name of the major river basin where the site is located, an 8-digit U.S. Geological Survey hydrologic unit code (HUC) for the associated river basin, and a code describing the site occupied (S_O) at the facility while collecting GPS data. The location for each facility was obtained by Geologic Survey Branch (GSB) personnel utilizing a Trimble Navigation global positioning satellite (GPS) receiver for data collection while occupying either the facility's intake pump at the discharge pond, spray field, or alternate location if any of the two previous locations were inaccessible.
The uncorrected positional data were corrected for various errors inherent in GPS positional data by processing with differential correction software and then the corrected coordinates were entered into this GIS database. The manufacturer's specifications for the Trimble Navigation GPS receiver, states a horizontal positional accuracy of +/- 5 meters after differential corrections are applied.
The database is intended for use 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 Watershed Protection Branch (WPB) and originated from their LAS permit files. Attributes selected for use in the GIS database are the county name, the facility's permit number and name, river basin, and LAS type.
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 WPB made a final review of the data; see the appendix A, signature sheet following part A.
The LAS 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 intake pump at the discharge pond, spray field, or an alternate location if either of the other two locations were inaccessible. The uncorrected GPS positional data were corrected for various errors inherent in GPS positional data by post-collection processing with differential correction software. The corrected coordinates were entered into this LAS database.
The LAS facility database was electronically overlaid with 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 to the LAS database by utilizing the database overlay capability of the GIS software ARC/INFO (version 7.2.1).
The database is being published at a scale of 1:24,000.
2.2 Logical Consistency
The LAS facility database was electronically overlaid with an existing county boundary database to check for 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 were made when errors were discovered.
2.3 Completeness
This database contains 211 permitted LAS facilities located within the state of Georgia. The database is current through 31 December 1999.
2.4 Positional Accuracy
The LAS 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 intake pump at the discharge pond, spray field, or alternate location. The uncorrected positional data were corrected for various errors inherent in GPS positional data by post processing with differential correction software. The corrected coordinates were entered into the GIS database. The manufacturer's specifications for the Trimble Navigation GPS receiver states 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
In summary, six previously completed LAS databases prepared by GSB for six river basins were appended into a single database. The reader is referred to the documentation reports in the Technical files at GSB for the previously developed databases, which are as follows:
DR96-26 - - Land Application Sites (LAS) Within the Chattahoochee-Flint River Basins in Georgia, Permitted Through August, 1996
DR97-04 - - Land Application Sites (LAS) Within the Coosa-Tallapoosa and Oconee River Basins in Georgia, Permitted Through August, 1996
DR98-18 - - Land Application Sites Within the Savannah-Ogeechee River Basins in Georgia, Permitted Through August, 1997
DR98-29 - - Land Application Sites (LAS) Within the Satilla, St. Marys, Suwannee, and Ochlocknee River Basins in Georgia , Permitted Through December 1998
DR99-07 - - Land Application Sites (LAS) Within the Ocmulgee River Basin in Georgia, Permitted Through February 1999
DR99-10 - - Land Application Sites (LAS) Within the Altamaha River Basin in Georgia , Permitted Through January 1999
In addition, the LAS facilities which were not included in the above databases, but which were permitted as of 31 December 1999, were added to the database. The principal source for the updating the facilities information were printouts of the WPB computer database which contains the associated data for each LAS facility as supplied by EPD's Watershed Protection Branch. For each facility, the county name, permit number, facility=s name, river basin, and LAS type (Municipal, Industrial, or Private) was copied from the source printout sheets by GSB personnel and manually entered onto a field data sheet for each facility.
The field data sheet was taken to its facility, where a GPS file name, date, time, GPS location occupied, an uncorrected latitude-longitude coordinate (from the GPS receiver), and other miscellaneous field notes as necessary were added onto the data sheet. Information from the field data sheets was typed into a Quattro Pro spreadsheet. Field data sheets were filed by county for future reference.
GPS data files were downloaded in the office from the GPS receiver into a personal computer. Differential correction was performed on the data files utilizing Trimble's PATHFINDER OFFICE software. Base station data for post-processing differential correction 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 at http://www.fs.fed.us/database/gps/atlanta.htm. The differentially corrected data from the GPS receiver was compared with the typed Quattro Pro spreadsheet and any major differences were reconciled.
The information from the six previously completed LAS databases and information for the LAS facilities which are not included in the six database, but which were permitted as of December 1999, were added together to make a master dBase for 1999 LAS data. This master dBase file was transferred to a NT workstation where the master file was processed in ARC/INFO (version 7.2.1) software by an EPA written program, dbf2cover, to create a geographic database, with each facility represented digitally as a point.
Then the LAS facility data 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 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.
3.0 Spatial Data Organization Information
This database contains the locations for the 211 permitted LAS facilities located within the state of Georgia. Each facility is represented digitally as a 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 attributes detailing pertinent information about the LAS facility. Information includes the database=s line number - record, the facility's permit number, its name, LAS types (municipal, industrial, or private), the county name, latitude and longitude coordinates (in degrees, minutes, and seconds) for the facility's intake pump at the discharge pond, spray field or alternate location, the name of the major river basin where facility is located, the HUC associated with the major river basin, and a code describing the site occupied at the facility while collecting GPS data.
6.0 Distribution Information
This database is maintained by the Geologic Survey Branch in their Technical Files, referenced as Land Application Sites (LAS ) Within The State of Georgia, Permitted Through 31 December 1999.
7.0 Metadata Reference Information
The metadata is incorporated within this publication, DOCUMENTATION REPORT 00-39. 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.

2.5.1.18.6 Source Contribution: GSB personnel collected GPS
information, compiled the information from the WPB computer printouts, processed the data into an Arc/Info GIS database files, and documented the database according to GSB standards.
2.5.2 Process Information:
Procedures used to create or automate data:
The data source for the updating documents for this statewide database were printouts of a computer database supplied by EPD's Watershed Protection Branch. These data files, WPB_EPD, listed information about all the permitted LAS facilities in the state. Those facilities not previously visited were targeted for GPS data gathering and for inclusion into this GIS database. For each facility, the name of the county, facility=s name and permit number, the river basin name, and LAS type (Municipal, Industrial, or Private) was copied from the source information by GSB personnel and manually entered onto field data sheets. GSB field personnel visited each facility with a Trimble Basic-Plus GPS receiver, with instructions to occupy the facility's intake pump at the discharge pond, spray field, or alternate location if either of the other two locations were inaccessible. The field personnel added the following information to the field data sheets while at each facility's location, the GPS file name, date, time, county name, the LAS name, the river basin name, the actual site occupied during the GPS data collection, and the uncorrected latitude-longitude coordinate read from the GPS receiver.
GPS files in the GPS receivers 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 (USDA), Forest Service Trimble base station located on top of the USDA
Southern Region Office at 1720 Peachtree Rd., Atlanta Georgia. The base station
data, USDA GPS, is available and downloadable via the Internet site, http://www.fs.fed.us/database/gps/atlanta.htm.
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 Quattro Pro spreadsheet. Field data sheets were filed by county for future reference.
The spreadsheet data were saved as a dBase file and then appended to another dBase file which contains data from the following 6 previously completed river basin coverages:
LAS_CF_RB: Land Application Sites (LAS) Within the Chattahoochee-Flint River Basins in Georgia, Permitted Through August, 1996 - DR96-26
LAS_CTO_RB: Land Application Sites (LAS) Within the Coosa-Tallapoosa and Oconee River Basins in Georgia, Permitted Through August, 1996 - DR97-04
LAS_SVO_RB: Land Application Sites Within the Savannah-Ogeechee River Basins in Georgia, Permitted Through August, 1997 - DR98-18
LAS_SSSO_RB: Land Application Sites (LAS) Within the Satilla, St. Marys, Suwannee, and Ochlocknee River Basins in Georgia, Permitted Through December 1998 - DR98-29
LAS_OCM_RB: Land Application Sites (LAS) Within the Ocmulgee River Basin, Permitted Through February 1999 - DR99-07
LAS_ALT_RB: Land Application Sites (LAS) Within the Altamaha River Basin, Permitted Through January 1999 - DR99-10
This master dBase file was transferred to a NT workstation where the file was
processed in ARC/INFO (version 7.2.1) software by the program DBF2COVER, (dBase file to GIS Coverage) written by the US Environmental Protection Agency (EPA), http://www.epa.gov/r10earth/dbf2info.html. This program converts a dBase file directly into a GIS database/coverage.
Then the facility location 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 correct county name, river basin name, and HUC 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.
