Aerial mapping of Islands by INCOIS

The Indian National Centre for Ocean Information Services (INCOIS) is planning to take the help of the National Remote Sensing Centre (NRSC) for aerial mapping of the Andaman and Nicobar Islands and Lakshadweep to get a better picture of the ocean floor, also called ‘bathymetric’ study.
“NRSC has already done a similar high-resolution topographic Airborne Laser Terrain Mapping (ALTM) for the entire coastal areas of the country and we are in the process of integrating the data for a 3D multi-hazard mapping of both the east and west coastline for a more precise picture of the ocean floor,” said director T. Srinivasa Kumar, in an exclusive interaction.
Such a study has become imperative in view of the recent tsunamis on the Indonesian coasts were more than the quake-related high waves, damage was due to landslides under the sea beds causing sudden wave surges leading to much damage without giving sufficient time to alert people, he pointed out.
The research institute, under the Ministry of Earth Sciences, had also identified ‘gaps’ across the coast of Andhra Pradesh and Odisha for installing more tide gauges for better monitoring of the sea and more accurate prediction of impending disasters like cyclones.
These will be in addition to the 36 already in the Bay of Bengal, said senior scientist E. Pattabhi Rama Rao.
INCOIS scientists with their counterparts in the Chennai-based National Institute of Ocean Technology and a United States independent scientific agency, Massachusetts-based Woods Hole Oceanographic Institution, have been mining the data recorded by a unique ‘Flux Buoy’ retrieved from the Bay of Bengal off the Kolkota coast recently.
