A High-Resolution Flood Inundation Archive (2016–the Present) from Sentinel-1 SAR Imagery over CONUS

Abstract: Most existing inundation inventories are based on surveys, news, or passive remote sensing imagery. Affected by spatiotemporal resolution or weather conditions, these inventories are limited in spatial details or coverage. Satellite Synthetic Aperture Radar (SAR) data has recently enabled flood mapping at unprecedented spatiotemporal resolution. However, the bottleneck in producing SAR-based flood maps is the requirement of expert manual processing to maintain acceptable accuracy by most SAR-driven mapping tec… Show more

“…On the other hand, if the information on flood occurrence exists and the AOI covering potentially affected areas is provided, the method could be used in the ondemand mode while using only its change detection results for approximate delimitation of floods extent. A similar approach was described in [10] where a unique triggering mechanism was developed based on gauge stations and satellite precipitation estimations, identifying potentially flooded zones. Similarly, alerts issued by national meteorological services could be used.…”

“…They focused only on the selected flood events themselves. Other authors, such as [10], do not operate their system permanently, but only in areas and at times when their triggering mechanism reported potential floods. We consider the presented long-term tests to be an essential part of the quality assessment of our developed solution.…”
