Description:
Abstract:
September 2000 Coastal Georgia Floridan Aquifer System surface in ArcInfo GRID format. This raster surface was derived using TIN in 3D-Analyst and Spatial Analyst in ArcGIS 8.3, with the Floridan well points and the manually created contours as input. Surface resolution is 100 meters, with Z-values as feet.
Purpose:
Can be used for spatial analysis anywhere surface input is required.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Water-level measurements made to within +- .03 feet. Land-surface elevations vary, but generally +1 10 feet. Calculated water surface elevation values are therefore dependent on the accuracy of the land-surface and water-level measurements.

Process_Step:
Process_Description:
Raster grid created from TIN of contours and pont data using wells (water-surface elevation) and manually drawn contours as input. Coastal counties used as boundary. Point data input as mass points, contours as hard lines. Converted to raster with 100 meter cell size.
