DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Raster surface for transmissivity of the Upper Floridan aquifer

Metadata Updated: November 12, 2020

Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Groundwater Resources Program. This feature class contains a gridded surface depicting the transmissivity of the Upper Floridan aquifer in feet squared per day.The well site data, from the TransmissivityWells.shp shapefile, containing 1487 transmissivity estimates, in units of feet squared per day, were used to produce this raster grid. The Geostatistical analyst inverse-distance weighting interpolation tool was used on the log10T field with weights from the weight field. Transmissivity estimates using test type, single- and multi-well aquifer tests (APT) were given a weight of 1.0 and specific capacity (SPC), a weight of 0.5. The map shows the estimated transmissivity based on interpolation of aquifer tests at the 1487 locations in units of log base 10 square feet per day.
