Inundation maps of Recent Flood Events from RAPID (Sentinel-1)


The inundation maps in GeoTiff format are generated from 10 m resolution Sentinel-1 images using the automatic RAdar Produced Inundation Diary (RAPID) algorithm. Inundation (pixels with label 1) refers to non-obstructed flooding only. The maps can only be used for non-commercial research, educational, and humanity purposes only. Please cite our publications when using/redistributing the maps. We acknowledge Amazon Web Service (AWS) for providing us the storage to share of  all flood events in the CONUS area detected by the RAPID system from 2016-present  (
