Glacial lake inventory from 1977-2017, based on Landsat MSS/TM/ETM+/OLI imagery, uses a semi-automatic water body classification method to distinguish between water body and non-water body information, then extracts the lake boundaries and visually checks and manually edits them by comparison with the original Landsat images. The MSS sensor data was used in 1977 with a resolution of 60 m. Image data used after 1987 had a resolution of 30 m.The relationship between glacial meltwater and glacial lake recharge was determined from RGI 6.0 and Google Earth.

File naming and required software

Glacial lake catalogues are named after the year of the source image + GL (glacial lake). For example, 1987_GL means that the glacial lake was catalogued in 1987. The data format is shapefile and can be used with software such as QGIS or ArcGIS.
