DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Points and control points for the top of the 10,000 mg/L total dissolved solids boundary

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 est_10000_TDS raster. It also includes "control" points used to map the 10,000 boundary including time-domeain electromagnetic soundings, data source is written communication from Pat Burger, St. Johns River, Water Managment District, 2013 and from other sources.本数据集作为美国地质调查局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，生成了佛罗里达含水层系统（Floridan aquifer system）中选定水文地质单元的数字地表与厚度数据。本要素类（feature class）包含用于生成est_10000_TDS栅格的数据点，同时还涵盖用于绘制10000号边界的“控制”点位，其中包括时域电磁测深（time-domain electromagnetic soundings）数据。数据来源包括2013年圣约翰河水资源管理区（St. Johns River Water Management District）的帕特·伯格（Pat Burger）提供的书面沟通资料，以及其他相关数据源。
