Remotely sensed information from satellites and airborne instruments can be used for estimating the extent and dynamics of flood inundation for large areas and can complement in-situ observations. IWMI’s flood risk spatial datasets contain estimated maximum flood inundation extent for South Asia, Southeast Asia and Nigeria.
