What
In this online series we combine the power of GIS (Geographic Information System) with OSM (Open Street Maps), DEM (Digital Elevation Model) data and external natural data sets to study and analyze the geography of the Himalayas, terrain analysis, plan Himalayan traverses, geo-reference maps, study mountain ranges & eco regions, analyze climate & weather data, visualize hydrology through basins and rivers and glaciology.
