Erosion trend analysis of coastline along ponnani region using multitemporal images

A study of coastal erosion along the Ponnani coast using multispectral imageries and GIS was undertaken to assess the temporal changes in coastal erosion, its extent, magnitude, and trends in the region under study. The study utilized medium resolution LANDSAT imageries for the mapping and monitoring of the coastline erosion. The digital image processing software used for calculating the erosion rate was TNTmips 2014 professional version (Map and Image Processing System - MIPS) by MicroImages, Inc. Results showed that many places along the Ponnani shoreline are under severe erosion.
