HydroATLAS v1.0
HydroATLAS为HydroBASINS的所有子流域、HydroRIVERS的所有河段和HydroLAKES的所有湖泊多边形提供了一个全球水环境特征汇编。HydroATLAS数据库分为三个不同的子数据集。BasinATLAS、RiverATLAS和LakeATLAS,分别代表子流域的划分(多边形)、河网(线)和湖岸线(多边形)。HydroATLAS总共包含100万个子流域、850万条河流和140万个湖泊。

HydroATLAS是通过对来自现有全球数据集的广泛的水文环境属性进行汇编和重新格式化,以一种一致和有组织的方式创建的。由此产生的数据汇编提供了分为七类的属性:水文;地形;气候;土地覆盖和使用;土壤和地质;以及人类活动的影响。对于这三个子数据集中的每一个,HydroATLAS都包含56个水文环境变量,被划分为281个单独的属性。你可以在这里下载这些文件

由于丰富的属性信息,HydroATLAS数据库以大文件的形式分布。只需要子流域边界、河网线和湖岸线的几何信息和数字矢量图的用户可能更愿意下载HydroBASINS、HydroRIVERS或HydroLAKES产品来代替。
