|title||Glacial lake inventory of High Mountain Asia|
The data set integrated glacier inventory data and 668 Landsat TM/ETM+/OLI images, and adopted manual visual interpretation to extract glacial lake boundaries within a 10-km buffer from glacier terminals using ArcGIS and ENVI software, normalized difference water index maps, and Google Earth images. It was established that 27,205 and 30,121 glacial lakes in HMA, with sizes of 0.0054–6.46 km2, covered a combined area of 1806.47 ± 2.11and 2080.12 ± 2.28 km2 in 1990 and 2018, respectively.The current glacial lake inventory provided fundamental data for water resource evaluation, assessment of glacial lake outburst floods and gacier hydrology research in the mountain cryosphere region.
|time:||1986/07/01 - 2019/11/30|
|location||A region of 10-km buffer from glacier terminals in the HMA.|
|altitude||6247.0 - 1357.0|
|file size||30.874 M|
Accuracy of Data： (1) The percentage difference of the absolute area encircled by the manually delineated lake boundary and that derived by the GPS survey varied from 5.5–25.5 %. (2) The average accuracy of the delineation of glacial lake boundaries was within ±0.5 pixels (±15 m). (3) The resulting calculated error indicated that the total absolute area error of HMA glacial lakes was approximately ±231.44 and ±259.68 km2 and the average relative error was ±13.8 and ±13.3 % in 1990 and 2018, respectively.
