Basin90m, a new global drainage basin dataset

The current global dataset of drainage system shapes has a relatively low spatial resolution. We obtained a new dataset (Basin90m) by calculating the drainage basins larger than...当前全球水系形态（drainage system shapes）数据集的空间分辨率相对偏低。本研究通过计算面积大于……的流域（drainage basin），构建了全新的Basin90m数据集。
