|
| SSA_ID |
Character string of the form "SSA_##" providing an identifier for the SSA designations. Since a given SSA can be located in more than a single county, a concatenation of the SSA_ID and the FIPS code are needed to establish a unique database key. Where polygons are provided for streamflow zones or other special features related to the SSA designations, the SSA_ID takes the form of SSA##a, SSA##b, or SSA##b. An example for an SSA designation involving 3 polygons areas is: SSA46a Edwards Aquifer II (Austin Area) SSA - Streamflow Source Zone 53 FR 20897 (1988); SSA46b Edwards Aquifer II (Austin Area) SSA -Recharge Zone 53 FR 20897 (1988); SSA46c Edwards Aquifer II (Austin Area) SSA - Artesian Zone 53 FR 20897 (1988).
|
|
| FR_ID |
Character string of the form "## FR #### (YYYY)" providing an identifier for the Federal Register citation for the SSA designations. Attribute_Definition_Source: Computed based on SSA_IDs developed for the Drinking Water Mapping Application and information in Federal Register Notices and GIS attributes in polygons supplied from the EPA Regions.
|
|
| AQUIFER |
Originally named SSA_NAME. The name of the SSA taken from the Federal Register and corresponding to a given SSA. The name will contain information related to the streamflow zone or other special features related to a specific polygon.

The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist. Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. The University of Florida GeoPlan Center shall not be liable for any damages suffered as a result of using, modifying, contributing or distributing the materials. A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

GeoPlan Center downloaded the US EPA National Sole Source Aquifer
layer from the following US EPA website via Internet Explorer:
https://edg.epa.gov/clipship/
GeoPlan created a selection box that included the
State of Florida (1).
Next GeoPlan used the Select Data (2) section of the EPA Clip N Ship
to choose the following:
EPA Office of Water
OW Sole Source Aquifers
Next GeoPlan Selected a Vector Format (3) of File Geodatabase (.gdb)
Next GeoPlan Selected a Raster Format (if needed) (4) of File Geodatabase (.gdb)
Next GeoPlan Selected Spatial Reference (5) of WGS 1984
Next GeoPlan Selected the Download button.
Next GeoPlan Extracted the zipfile with the data.gdb
Next GeoPlan Reprojected the OW_Sole_Source_Aquifers
File Geodatabase feature class (WGS 1984) to FGDL Albers.
Next GeoPlan Converted the File Geodatabase feature class to .SHP
Next GeoPlan added and populated the following fields; DESCRIPT and FGDLAQDATE
Process Date: 20120824
