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 thickness of the glauconite marker unit in feet. It was calculated by surface subtraction: fig48_top_GlaucUnit_raster - fig49_top_OLDSPZ_raster
