Water Spread Area Dynamic of Chilika Lake: A Geospatial Approach

Abstract

Chilika lake is the largest lagoon in Asia on the east coast peninsular India covering about hundred thousand hectares of land, one among six Indian wetlands declared under the Ramsar convention in 1982. Lake shrinkage is another important ecological transformation. This may be due to several factors, both natural and human. The study area is Chilika Lake which is located at 19°27’58.081”N–19°53’24.438”N latitude and 85°6’5.301”E–85°40’36.149”E longitude on the east-coast of the state of Odisha, India. The objective is to prepare a database of the pre and post monsoon period water spread area of the lake from time series satellite imageries. The geospatial technique has emerged as the most important tool of a geographer to handle the spatio-temporal data. It is now widely used around the world to analyse physical as well as cultural geographical elements. The output will be utilized in several regional and micro level planning, monitoring and management for community development.
