United States Aquifer Database

Here we present a geospatial dataset representing local- and regional-scale aquifer system boundaries, defined on the basis of an extensive literature review and published in GebreEgziabher et al. (2022). Nature Communications, 13, 2129, https://www.nature.com/articles/s41467-022-29678-7

The database contains 440 polygons, each representing one study area analyzed in GebreEgziabher et al. (2022). The attribute table associated with the shapefile has two fields (column headings): (1) aquifer system title (Ocala Uplift sub-area of the broader Floridan Aquifer System), and (2) broader aquifer system title (e.g., the Floridan Aquifer System).

本研究发布一套地理空间数据集，用于表征局地与区域尺度的含水层系统边界。该数据集基于广泛的文献调研构建，相关成果已发表于GebreEgziabher等人（2022）的研究，刊载于《自然·通讯》（Nature Communications）第13卷，文章编号2129，原文链接：https://www.nature.com/articles/s41467-022-29678-7

该数据库包含440个多边形要素，每个要素对应GebreEgziabher等人（2022）中分析的一处研究区域。与该形状文件（shapefile）关联的属性表包含两个字段（列标题）：(1) 含水层系统名称（即广义佛罗里达含水层系统（Floridan Aquifer System）的奥卡拉隆起子区域）；(2) 广义含水层系统名称（例如佛罗里达含水层系统）
