DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- General area 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 contains a generalized polygon used for clipping of other features in this dataset.

本数据集于2016年10月1日美国地质调查局（U.S. Geological Survey，USGS）科学数据审核、批准与发布政策生效前发布，该政策依据《美国地质调查局勘测手册第502.8章：基础科学实践——科学数据发布的审核与批准》制定。作为美国地质调查局地下水资源计划的组成部分，本数据集编制了佛罗里达含水层系统典型水文地质单元的数字表面与厚度数据，用于构建更新版水文地质框架。本要素包含一个用于裁剪本数据集内其他要素的广义多边形。
