Abstract: The purpose of the study was to develop an integrated coastal zone management plan for South Andaman Island and for this study, three dimensional elevations models; coastal biodiversity and landuse/ landcover pattern changes were analyzed. Spot 1993 and IRS-P6 Jan 2007 Satellite imagery was used for estimating the landuse changes. Three dimensional elevations models, drainage pattern and landuse change map were overlaid for developing an integrated coastal zone management for South Andaman Island which will enable for the sustainable development and management of this island.
