Indian Cartographer, 2002 CMMC-01 147 USE OF SATELLITE DATA IN COASTAL MAPPING (invited paper)

The coastal zone is dynamic, both natural and anthropogenic processes continue to modify it. The loss of habitats, coastal erosion and appropriate site selection are some of the issues faced by the coastal managers. One of the major requirements for the coastal zone management is availability of up-to-date and accurate information on coastal habitats, shoreline processes and water quality. Remote sensing data, especially from IRS series, have been found to be very useful in providing vital inputs on condition of wetlands, mangroves, coral reefs, coastal land use, coastal erosion and deposition, delineation of high and low tide and construction setback lines, etc. Satellite based coastal maps have an accuracy of 85 to 90 per cent at 90 per cent confidence level
