DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Outcropping areas of the Floridan aquifer system

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 polygons showing the areas where the aquifer system outcrops. This feature class was developed from state geologic maps.

本数据集作为美国地质调查局（U.S. Geological Survey）地下水资源计划的组成部分，旨在构建更新版水文地质框架，涵盖佛罗里达含水层系统（Floridan aquifer system）选定水文地质单元的数字表面与厚度数据。该要素类（feature class）包含用于标识该含水层系统裸露区域的面状要素。本要素类基于各州地质图编制而成。
