The FDEP 15m DEM was used for the land surface and the top of rock was develoed by using Florida Geological Survey well core and cuttings data. The surface was interpolated using simple kriging. Overburden is created by subtracting the top of rock grid from the land surface grid.

This data was used to create a stratigraphic surface of the top of FAS. The surface was interpolated by using the kriging method. Areas calculated above land surface were set equal to land surface. To get a thickness of overburden the top of FAS surface was subtracted from the top of land surface surface. 2009 Advanced GeoSpatial Inc. mailing and physical address
