Depth to ground water of Nevada

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. This is a raster-based, depth to ground-water data set for the State of Nevada. The source of this data set is a statewide water-table contour data set constructed from water-table contours collected from 1947 to 2004 and published in 38 reports from 1961 to 2004, depth to ground water contours from Static Ground Water Levels of Nevada published in 1974, and depth to ground water contours from Diamond Valley published in 2006.

本数据集的发布时间早于美国地质调查局（United States Geological Survey，简称USGS）于2016年10月1日生效的科学数据审核、批准与发布政策，相关政策依据参见USGS调查手册第502.8章《基本科学实践：科学数据发布的审核与批准》。本数据集为美国内华达州（State of Nevada）的基于栅格的地下水埋深数据集，其数据源包含三部分：一是基于1947年至2004年间采集的地下水位等值线构建的全州地下水位等值线数据集，相关成果发表于1961年至2004年间的38份报告；二是1974年出版的《内华达州静态地下水水位（Static Ground Water Levels of Nevada）》中的地下水埋深等值线；三是2006年出版的《钻石谷（Diamond Valley）》中的地下水埋深等值线。
