Satellite Remote Sensing data arc being extensively used in change detection and vegetation cover studies. Visual interpretation of LANDSAT imagery, black and white aerial photographs, colour Infra-red aerial photographs, diazo false colour composites of LANDSAT imagery, computer enhanced image, digitized image and stereoscopic photo interpretation techniques were adopted for the study of change detection and vegetation cover of “Nijhumdwip”. The purpose of the study was to find out the rate of accretion and the succession of vegetation in the island. Groundtruth missions were performed for the collection of data. Information generated by the various methods of interpretation were correlated with known field data.
