DATASETS and OUTCOMES - Assessment of intrinsic aquifer vulnerability at continental scale through a critical application of the DRASTIC method: the case of South America

A robust and comprehensive assessment of intrinsic aquifer vulnerability at continental scale map may represent an essential initial step towards a more sustainable land-use and water management. This repository contains the outcomes of an intrinsic aquifer vulnerability assessment of South America, performed by the DRASTIC method. The assets included in this repository are mainly raster maps (.tif, .geotif), created and georeferenced in QGIS (v3.16). Coordinate reference system (CRS) of the dataset is WGS84. Technical specifications of all graphical outcomes are stored in a dedicated file (README.txt).开展大陆尺度的含水层固有脆弱性稳健且全面的评估与制图工作，可为实现更可持续的土地利用与水资源管理奠定必要的前期基础。本数据集仓库包含采用DRASTIC方法完成的南美洲含水层固有脆弱性评估成果。本仓库收录的资源以栅格地图（.tif、.geotif）为主，均通过QGIS（v3.16版本）完成制作与地理配准。本数据集的坐标参考系统（Coordinate Reference System, CRS）为WGS84。所有可视化成果的技术规格均存储于专属文件README.txt中。
