Abstract: The aim of this study is to bring out coastal geomorphological landforms from Thondi to Muthupettai area using remote sensing, GIS and field information. It is in the survey of India toposheets No. 58 0/1 and 58 0/2, 58 N/4 and 58 N/8, 58 N/7 in a scale of 1:50,000, 1:250,000. The study area contains three types of coastal geomorphologic landforms; they are depositional, erosional and other features. The depositional features like, beach, sand dune, beach ridges, spit, lagoon and mudflats. The erosional features like sea cliffs and other features like, salt pan, backwaters and mangroves, creeks and deltas. Extensive fieldwork has been undertaken to confirm the presence of different geomorphic landforms which are identified from earth observation system. From the analysis, it has been found that the satellite data is very useful and effective for getting the results of temporal changes. The present study exhibits the potency of GIS in representing the spatial distribution of various coastal geomorphological landforms. A GIS database was developed and updated in order to provide access for future use and computer analysis. These coastal landforms are indicating that the study area had the emerging types of the coastline.
