Digital polygon dataset of Snow Cover Area of Pakistan. This dataset is Basic grid layer derived from ESRI Map & Data 2001.

Digital polygon data of Glaciers of Bhutan in 2010. This dataset is created using Landsat TM and ETM+, imageries of 2010. 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.

Digital polygon data of Glaciers of Bhutan in 1980. This dataset is created using Landsat MSS imageries of 1980. 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.

Digital polygon data of Glaciers of Bhutan in 1990. This dataset is created using Landsat MSS and TM 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.

Digital polygon data of Glaciers of Bhutan in 2000. This dataset is created using Landsat TM and ETM+, imageries of 2000. 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.

Digital polygon dataset of location of Gyoko lake of Nepal. This dataset is created using Landsat TM, IRS and IKONOS satellite imageries under ICIMOD partnership with Wetlands International, ARGEOPS and Asia ProEco.

Digital polygon data of Glaciers of Central Karakoram National Park(CKNP) area, Pakistan. This dataset is created using topographic sheet maps at scale of 20000.

Digital polygon data of Glaciers of Hindu Kush Himalaya Region. This dataset is acquired from ESRI Map & Data Center in 2001.

The comprehensive baseline information on the glaciers of the HKH region was generated semi-automatically using more than 200 Landsat 7 ETM+ images of 2005 ± 3 years with minimum cloud and snow coverage. The glacier outlines were derived by using object-based image classification method separately for clean-ice and debris-covered glaciers with some manual intervention. The attribute data were assigned to each glacier using 90m resolution SRTM DEM.

The dataset shows areas identified as rock glaciers by two different persons (rock glacier mapping layer M1 and M2). It is obtained by intersecting M1 and M2 layer of rock glacier mapping.
