DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Point features for the thickness of the Floridan aquifer system

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. 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 thickness of FAS raster.

本数据集发布于美国地质调查局（U.S. Geological Survey, 简称USGS）科学数据审查、批准与发布政策的生效节点（2016年10月1日）之前，该政策详见USGS《调查手册》第502.8章《基础科学实践：科学数据发布的审查与批准》。佛罗里达含水层系统（Floridan Aquifer System, 简称FAS）选定水文地质单元的数字地表与厚度数据，系美国地质调查局地下水资源计划中为构建更新版水文地质框架而研发的成果。本要素类包含用于生成FAS厚度栅格的数据点集。
