DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Polygon regions depicting the low-permeability units that overlie 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 polygon regions of units that overlie the Lower Floridan aquifer. The regions are defined by geographic and hydraulic properties.

本数据集为美国地质调查局（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，其内容涵盖佛罗里达含水层系统（Floridan aquifer system）中选定水文地质单元（hydrogeologic unit）的数字地表与厚度数据。该要素类包含覆盖下佛罗里达含水层的单元多边形区域，此类区域由地理属性与水力属性共同界定。
