Indian National Centre for Ocean Information Services (INCQIS) an autonomous organization of MoES has prepared and published an atlas of Coastal Vulnerablllty Index (CVI) maps for the entire coastline of India at 1:100000 scale using data on sea level rise, coastal slope, shoreline change rate, coastal elevation, coastal geomorphology, tidal range and significant wave height. In addition, National Center for Coastal! Research (NCCR), Chennai, an attached office of MoES is monitoring the shoreline changes along the Indian Coast using satellite images. The study of 28 years satellite data by NCCR, i.e. (1990-2018) indicates that 33.6 % of Indian coast is eroding with varying rate of changes.
