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 of low-permeability units forming the LISAPCU

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 the LISAPCU related to the degree of confinement. The regions are defined by geographic and hydraulic properties.

本数据集针对佛罗里达含水层系统（Floridan aquifer system）中选定的水文地质单元（hydrogeologic units）的数字表面与厚度开发构建，作为美国地质调查局地下水资源计划（U.S. Geological Survey Groundwater Resources Program）的组成部分，旨在搭建更新后的水文地质框架。该要素类（feature class）包含与封闭程度相关的LISAPCU多边形区域，此类区域由地理属性与水力特性共同界定。
