Satellite Based Observations And Modeling Of Flood

Submitted by admin on Tue, 11/09/2018 - 17:02

Flood is a devastating natural disaster experienced generally during monsoon months due to torrential rainfall over different regions of India. This not only leads to large impact on the socio-economic life of the country but also result in large-scale destruction of life and property.

Village Level Vegetation Monitoring Using Resourcesat Data

Submitted by admin on Tue, 09/01/2018 - 17:24

Status of vegetation at village level plays an important role to assist policy makers as a decision support feature. Space Applications Centre, SAC/ISRO Ahmedabad has developed an automated system to compute village level NDVI through Visualisation of Earth observation Data and Archival System (VEDAS).

Antarctica : Larsen C Rift Propagation and Calving as seen since 5th April 2017

Submitted by admin on Fri, 01/09/2017 - 15:25

Rift Propagation and ice calving of Larsen C Ice Shelf in Antarctica. Calving of ice took place between July 10th and 12th. AMHTDG Team was watching the event closely. Ice disintegration was of the order of ~ 6200 km2 out of ~ 50000 km2. The event presently will not raise the sea level, but the instability of the shelf and increased ice flow from Ice Sheet may altogether change the scenario.
