  Flood Hazard Mapping of Sagar Island duringCyclone ?YAAS? Using Remote Sensing and GIS
  Author(s): Kundan Kumar Das*
  
  This paper is an attempt to delineate the flood area of Sagar Island after the event of cyclone ‘YAAS’. Delineation of such hazard is very difficult due to lack of geospatial data and technology. This paper tries to Use Open Source Data (USGS) and software packages (QGIS) which can be used to implement most recent technology available for the assessment of flood area in Sagar Island after the event of cyclone ‘YAAS’. For this study Landsat 8 OLI and TIRS (Free data source-USGS Earth Explorer) data have been used. An earnest attempt has been made to implement a complete process of hazard mapping of flood using remotely sensed data for both pre and post event of cyclone ‘YAAS’ in Sagar Island. This study tries to map both flood hazard and land use land cover of study area systematically for risk assessment. Built up area has been extracted by using ND.. View More»
