ddd Coastal Land Use/Land Cover maps and Coastal Regulation Zone map on 1:25,000 and 1:50,000 scales derived from satellite data were collected from State Coastal Zone Management Authorities and enlarged into 1:12,500 scale. The georeferenced maps were digitized in ARC-INFO GIS. Digitized maps were edited, labeled and a layout was prepared. The area statistics of different Ecologically Important Areas were generated and presented in the maps.
