Land use and Land cover plays a vital role in the aspect of change detection studies. Land use represents how the land is being used. It includes categories like agriculture, industrial lands. Land cover refers to natural or manmade properties. It includes waterbodies and vegetation. The ratio of Land use/Land cover represents eco system. More amount of industrial land than agriculture land refers to imbalance of eco system caused by industrial effects. This kind of complexities can be solved by Remote sensing in conjuction with change detection methods. The Temporal coverage of different Remote Sensing satellites provides information of Land use/Land cover of an particular area. Change detection is processing of identifying changes at different intervals of time. The amount of changes thus detected can help in predicting the impact on environment so that preventive measures can be taken when necessary. The main aim of this work is to study Land Use/Land cover changes for preparing future map.

The multi-temporal Landsat 7 ETM+ images acquired from 2011 to 2015 are used to demarcate the rate of shoreline shift using GIS-based Digital Shoreline Analysis System for the study area the coast between Kanyakumari and Tuticorin of the Tamil Nadu state, East Coast of India. The statistical analysis such as Shoreline Change Envelope, Net Shoreline Movement, End Point Rate, and Linear Regression Rate are determined from the multi-temporal shoreline layers. The data is streamlined on image processing software and analyzed using GIS technology indicating the suitability of DSAS to assess the shoreline changes compared with the traditional methods. The Tuticorin coast has experienced heavy accretion from 1969 to 2004, high amount of erosion in 2004. In present study of 2011 to 2015 the shoreline change has been considerably controlled.
