*5.1.1. Geospatial techniques*

The area between the shoreline and landward extent of the sandy beach was taken for estimating the PCC. The satellite images of the LISS IV for the year 2013 with spatial resolution of 5.8 m were used for calculation of the beach area along with extensive field verifications. Onscreen digitization of beaches was made using visual interpretation techniques. The field surveys were carried out using GPS track mode in each of the beaches for calculating exposed areas of beaches during high and low tides.
