Florida Geological Survey unknown raster digital data Florida Aquifer Vulnerability Assessment: Contamination potential of Florida's principal aquifer systems FGS Bulletin 67 The Floridan Aquifer System Response layer is the relative vulnerability map for the Floridan Aquifer System. It was calculated using the ArcSDM extension and applying the weights of evidence and logistical regression method. The total number of unique conditions, number of training points per unique condition, evidential theme generalizations and posterior probability are contained in the table. A relative vulnerability class field is also in the table so that the grid can be symbolized based on FAVA vulnerability zones.

Although efforts have been made to make the information accurate and useful, the FDEP/FGS assumes no responsibility for errors in the information and does not guarantee that the data are free from errors or inaccuracies. Similarly FDEP/FGS assumes no responsibility for the consequences of inappropriate uses or interpretations of the data. As such, these digital data are distributed on "as is" basis and the user assumes all risk as to their quality, the results obtained from their use, and the performance of the data. FDEP/FGS bears no responsibility to inform users of any subsequent changes made to this data. Anyone using this data is advised that precision implied by the data may far exceed actual precision. Comments on this data are invited and FDEP/FGS would appreciate that documented errors be brought to staff attention. The development of these data sets represents a major investment of staff time and effort. As a professional responsibility, we expect that the FDEP/FGS will receive proper credit when you utilize these data sets.

It was calculated using the ArcSDM extension and applying the weights of evidence and logistic regression methods. An analysis extent (study area), training point theme (fas_training_pts.shp), and modeling method (weights of evidence, logistic regression) are selected in the set analysis parameters. Weights are then calculated on each evidential theme and then the themes are generalized (into binary patterens, ias_thk is the exception with three classes). 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. The total number of unique conditions, number of training points per unique condition, evidential theme generalizations and logistic regression posterior probability are contained in the table. A relative vulnerability class field is also in the table so that the grid can be symbolized based on FAVA vulnerability zones.
