Unknown raster digital data \\Agisdc01\W\Projects\2008\PR2008-024_ColumbiaAVA\final_grids\response response The CCAVA Response theme grid is the relative vulnerability map for the Floridan Aquifer System. It was calculated using the ArcSDM extension and applying the weights of evidence method. A relative vulnerability class field is also in the table so that the grid can be symbolized into 3 vulnerability classes. These classes were developed based on logistic regression vs. cumulative area breaks.

(AGI) to provide SRWMD with a ground-water resource management and protection tool to carry out agency responsibilities related to natural resource management and protection regarding the Floridan Aquifer System.

Unknown Unknown Florida Aquifer Vulnerability Assessment: Contamination potential of Florida's principal aquifer systems FGS Bulletin 67 Raster Dataset Florida Geological Survey Unknown Unknown The CCAVA Response Theme grid is the relative vulnerability map for the Floridan Aquifer System. It was calculated using the ArcSDM extension and applying the weights of evidence method. An analysis extent (study area), training point theme, and modeling method (weights of evidence) are selected in the set analysis parameters. Weights are then calculated on each evidential theme and then the themes are generalized (into binary patterns). A generalization of 1 represents "more vulnerable" areas, 2 represents "less vulnerable areas and -99 represents missing data. A response theme is then calculated based on the association between training points and evidential themes. Weighted logistic regression is utilized in this step to remove the bias caused by inter-related evidential themes A relative vulnerability class field is also in the table so that the grid can be symbolized into 3 vulnerability classes . 2009 Advanced GeoSpatial Inc. mailing and physical address
