Description
We develop a HMA Glacial Lake Inventory (Hi-MAG) database to characterize the annual coverage of glacial lakes from 2008 to 2017 at 30 m resolution. This is the first glacial lake inventory across the HMA providing details for different types of glacial lakes at high spatial resolution, evolution patterns, and the first with annual temporal resolution. Although the method of lake mapping was automatic, for quality control every lake polygon was inspected and was manually edited where needed. It can be used for studies on the complex interactions between glacier, climate and glacial lake, glacial lake outburst floods, potential downstream risks and water resources.
Notes
The creation of this data set was funded by the Strategic Priority Research Program of the Chinese Academy of Sciences (XDA19030101), the International Partnership Program of the Chinese Academy of Sciences (131211KYSB20170046/131C11KYSB20160061), and the National Natural Science Foundation of China (41871345). SA was supported by the EVOGLAC project under the Swiss National Science Foundation (IZLCZ2_169979/1).
