DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Points for the top of the Lower Floridan aquifer

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 data points used to generate the top of the Lower Floridan aquifer raster.为构建更新版水文地质框架（hydrogeologic framework），作为美国地质调查局（U.S. Geological Survey）地下水资源计划（Groundwater Resources Program）的组成部分，研究人员生成了佛罗里达含水层系统（Floridan aquifer system）内选定水文地质单元（hydrogeologic unit）的数字表面与厚度数据。本要素类（feature class）包含用于生成下佛罗里达含水层顶部栅格数据（Lower Floridan aquifer raster）的数据点。
