全球湖泊/水库表面延伸数据集（GLRSED）

全球湖泊/水库地表水范围是许多研究的基本输入数据。虽然目前已有一些数据集，但由于数据来源不同、地表水动态变化特征等各种原因，数据集之间存在不完整或空间不一致等问题。在此，基于 HydroLAKES、GRanD 和 OpenStreetMap，制作了一个新的全球湖泊/水库水面范围数据集...

Global surface water extents of lakes and reservoirs serve as fundamental input data for a wide range of research studies. While several existing datasets are available, they suffer from issues such as incompleteness or spatial inconsistency due to factors including disparate data sources and the dynamic changing characteristics of surface water. Herein, we have developed a novel global dataset of lake and reservoir surface water extents based on HydroLAKES, GRanD, and OpenStreetMap.
