Digital point dataset of location of Hydrological Stations of Koshi Basin. The dataset is created based on data from Department of Hydrology & Meteorology, Nepal.

Digital dataset of Land cover of 2000 Sagarmatha National Park, Nepal. This dataset is created using LandSat ETM+ satellite image of 2000 October 30.

Digital polygon dataset of rainfall erosivity factor (R) of Koshi basin. The dataset is created using rainstorms of Nepal, India and China from world climate precipitation data. R-factor is computed as the average annual sum of the erosivity of the individual rainstorms, which is calculated as the product of total storm energy and maximum 30-min intensity. R-factor was evaluated from world climate precipitation data with equation (Renard and Freimund, 1994): R = 0.0483*P1.610 where P= annual precipitation (mm).

Digital polygon dataset of Hotels and Lodges of Sagarmatha National Park, Nepal. This dataset is created using Topographic sheet data at scale of 25,000/50,000, of 1995 acquired from National Geographic Information Infrastructure Project (NGIIP), Dept. of Survey, Nepal and Tourist maps published by various map publishing companies.

Land System vector digital data build based on Land System Map (1:50,000), Land Reource Mapping Project (LRMP), Dept. of Survey, 1986.

This is the first inventory of glacial lakes of Nepal Himalaya. The data is prepared using topographic maps, aerial photographs and satellite images.

Digital polygon dataset of Water bodies (river, pond, lake, glaciers etc.) of Sagarmatha National Park, Nepal. This dataset is created using Topographic sheet data at scale of 25,000/50,000, of 1995 acquired from National Geographic Information Infrastructure Project (NGIIP), Dept. of Survey, Nepal.

Digital grid dataset of Slope Steepness factor (S) of Koshi basin. It represents the effect of slope steepness on erosion. Soil loss increases more rapidly with slope steepness than it does with slope length. Slope steepness is derived from SRTM DEM 90 meter spatial resolution data.

Digital Elevation Model of Gyoko, Nepal is based on Topographic map scale 1:25,000/50,000 acquired from National Geographic Information Infrastructure Project (NGIIP), Dept. of Survey Kathmandu Nepal.
