Cryosphere datasets

Glacier data of Afghanistan was prepared based on Landsat imageries of 2015. The glacier outlines were derived semi-automatically using object-based image classification (OBIC ) separately for clean-ice and debris-covered glaciers and further manual editing for quality assurance. The attribute of glacier data were derived from SRTM DEM. This data was jointly prepared by the Ministry of Energy and Water (MEW), Afghanistan and Cryosphere team of ICIMOD with the support of SERVIR HKH.

Digital polygon data of Glaciers of Bhutan in 1990. This dataset is created using Landsat MSS, imageries of 1990. The glacier outlines was derived semi-automatically using object-based image classification (OBIC ) method separately for clean ice and debris cover and further editing and validation was done carefully by draping over the high resolution images from Google Earth.
