Application of Geographic Information Technology with satellite imageries have a vital role in shoreline studies. The Present paper highlights the application of this technology to explore the changes in the coastal tract. The prime aim of the paper is to locate the major changes in terms of erosion and deposition during a period of Four decades. A comparative study had gone using shorelines those extracted from toposheet and satellite imageries between (1972 to 2013). From the extracted Shorelines, changes have identified, Further DSAS employed for getting the Linear Regression Rate(LRR) for the area. The shoreline taken as a length of 9.3 km and it buffered 3 km it having 19.1 km2 of land and 22.62 km2 of sea for the given study. There found a drastic erosional changes. And the studies examine the area is under the threat of erosion with an average of –4.13 m/year
