<p>This dataset is based on glacier catalogue data and 668 landscape Landsat TM/ETM+/OLI images, combined with ArcGIS and ENVI software, NDWI and Google Earth images, and extracted by manual visual interpretation in a buffer zone 10 km away from the boundary of the glacier Icy lake boundary.
In the 1990 and 2018 glacial lake data sets, there are 27,205 and 30,121 glacial lakes in the High Asia region, with an area range of 0.0054-6.46 km2, with a total area of 1806.47±2.11 and 2080.12±2.28 km2, respectively. This glacial lake cataloging data set provides basic data for water resource evaluation in high Asia, evaluation of glacial lake outburst flood, and glacier hydrology research.
