Tamil Nadu, Andhra coasts now on 3D GIS map

Hyderabad, India: Indian National Centre for Ocean Information Services (INCOIS) is ready with multi-hazard vulnerability 3D-GIS maps of the India’s Tamil Nadu and Andhra coasts, according to INCOIS scientist Dr RS Mahendra. However, these maps are due to come out.
These maps aim to strengthen the protection of coastal belt from tsunamis and cyclonic floods. They will pinpoint the exact areas liable to be submerged in case of natural calamities.
Mahendra said, “We know coastal areas are vulnerable to tsunamis, cyclonic floods and storm surges. But till now we did not know which areas were prone to be submerged. Using the latest digital technology we are now mapping the entire coastal belt. This will help us zero in on the exact localities which have a high risk of being affected when a natural disaster hits the coast. Using the maps, we can take precautionary measures and prevent loss of lives.”
The INCOIS team used parameters like historical storm surge heights, future sea level, future shoreline and high resolution coastal topography to identify areas prone to natural calamities. The coastal population is under threat due to future storms, erosion and accelerated sea level rise.
“The INCOIS maps will become vital tools for coastal disaster management in the event of a natural crisis and to take a suitable decision on future developments,” he added.
