Surface Water Area Detection And Extraction By Using Different Techniques Of Remote Sensing And GIS.

Abstract

Jayakwadi dam built in 1976, is located in Jayakwadi village in Paithan taluka of Chhatrapati Smbhaji Nagar district in Maharashtra, India. Monitoring the surface water area of Jayakwadi Dam is important task because the main purpose of dam water is for drinking water as well as supply to industrial area for Chhatrapati Sambhaji Nagar city people and irrigation. The surface water area can be easily estimated with the help of satellite imagery and remote sensing and GIS technique. The data used to estimate surface water area is Landsat-8 satellite multispectral data. Landsat-8 has resolution of 30 Meter. We used mainly data of 8 Years from 2014 to 2022. NDWI and Maximum likelihood classification technique to estimate surface water area. As compare to maximum likelihood classification, NDWI and water pixel extraction is more accurately calculate the surface area of water reservoir. In this paper the maximum likelihood classification as well as NDWI method comparatively used to find out the surface water area by satellite image.
