Application of Remote Sensing in Coastal region- A Case study: Coastal threats, Image analysis, Image processing

The coastal environment presents serious problems to land use due to flooding, erosion, pollution, and emerging threat posed by rising sea level. All these require constant monitoring and remedial action in order to preserve man’s investment. The developments in the field of remote sensing by collecting multi temporal data through earth observing satellites make it possible to monitor the coastal zone effectively. This approach provides cost effective and accurate solution to various coastal management problems. In this study an attempt have been to analyze the changes in the coastal environment in Vasai creek, Mumbai using remotely sensed digital data. The shoreline behavior along the creek also analyzed in order to ascertain the stability of the coast. Water quality assessment using the visual interpretation was carried out and the dispersion of polluted water in the sea was studied. The changes in the land form features were quantified using unsupervised classification technique and which will be vital information for coastal planning for development works and protection works.The coastal environment of Vasai creek between the years Jan 1999 and Feb 2001.
