The Space Applications Centre has developed techniques for mapping and monitoring of Himalayan glaciers using satellite data. Remote sensing based techniques, models and methods to generate a large amount of digital database and maps to understand the state of Himalayan cryosphere has now assumed greater significance when the nation needs to address a large number of questions about the health and state of glaciers. There is no contemporary technique which provides this information to the nation in a very short span of time, and for a large number of glaciers occurring in inaccessible regions.
