Datasets description

    This dataset is based on glacier cataloging data and LandsatTM/ETM+/OLI images, combined with ArcGIS and ENVI software, NDWI, and Google Earth images. The glacial lake boundary within a buffer zone 10km outward from the glacier boundary is extracted through manual visual interpretation. This includes two periods of glacial lake data from 1990 and 2018, providing basic data for water resource evaluation, glacial lake outburst flood evaluation, and glacier hydrological research in Gansu region.
