DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Raster surface depicting the top of the APPZ

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 the top of the Avon Park permeable zone in feet relative to NGVD29.

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，研究人员针对佛罗里达含水层系统（Floridan aquifer system）中选定的水文地质单元，构建了其数字曲面与厚度数据集，旨在建立更新后的水文地质框架。该要素类（feature class）包含一幅栅格表面数据，用于表征埃文帕克透水带（Avon Park permeable zone）的顶部高程，其高程以英尺为单位，且以1929年国家垂直基准面（NGVD29）为基准。
