The present study illustrates the integral approach of remote sensing and GIS for the assessment of coastal environment of a part of coastal Odisha. Multispectral and multi-temporal Landsat satellite imageries along with Linear Imaging Self scanning Sensor (LISS IV) data were used to carry out this piece of work. In this paper, an attempt has been made to study the coastal dynamics i.e., landuse/landcover (LULC), erosion and accretion of a part of Odisha coast (Baleswar, Bhadrak, Kendrapara and Jagatsinghpur districts). Supervised classification adopting maximum likelihood method was applied to analyze this work. The study resulted in different classes like Sand, mangroves, wetland, Plantation with settlement, forest, agricultural land etc. The LULC map showed that the area under plantation with settlement was larger than any other class and it also showed reduction of agricultural land in all the districts of the coastal environment. Similarly, mangroves increased in all the coastal districts. Shoreline changes (Erosion and accretion) were identified through maximum likelihood method. The analysis of LULC and shoreline changes in the study area revealed significant variations. The result showed increase in plantation with settlement and decrease in agricultural land. The map prepared for this research will contribute to both the landuse planner as well as the coastal planners for shoreline protection measurement.
