摘要：In the present study, an attempt has been made to classify the near shore substrate types as well as coral reef environment using Landsat and IRS sensors. An analytical approach has been applied to extract the bottom reflectance and finally the supervised classification has been applied to delineate different ecologically sensitive classes. The classification made with raw bands is compared with the classified map generated taking bottom reflectance and water leaving radiance image. The results indicated that much of the submerged feature got exposed after applying atmospheric correction and bottom reflectance retrieval algorithms. In the present study, an attempt has been made to demarcate suitable sites for coral polyp plantation using the classified image and lagoon bathymetry of Minicoy. It has been found that 23 % of the total lagoon area is suitable for coral polyp plantation
