WATER BODIES EXTRACTION OF JHARKHAND USING RS AND GIS
Keywords:
Abstract
Surveying of water-bodies and delineating its features is vital for any planning, especially for India, where the land-cover is dominated by water-bodies. Extraction of water bodies using spatial inputs has been the most important method in the investigation of water resources, flood hazard prediction assessment and water planning with better effectiveness. A methodology for water extraction mapping using an integrated GIS and RS approach is presented, where in an endeavour has been made to put forward an automatic approach to extract the water bodies from satellite imagery. In this study, various methods were used for water body extraction like as Supervised Classification, Unsupervised Classification, Normalized Difference Water Index (NDWI), and Water Bodies Extraction Index (WBEI). WBEI it is a newly developed index used mainly for water body extraction. Landsat satellite data was used as inputs to the methodology. In this research water bodies were identified and corresponding thematic data layers were created. These data layers represent the hydrological conditions of the study area. The result obtained from different methodology was compared with each other. Part of the Jharkhand state was selected as the study area to evaluate and analyze which water extraction method is most effective and quick for water bodies’ identification. On the basis of visual interpretation of different methodology results, WBEI methodology showed good result and exact area of water body as has been depicted in the paper.
