NASAs ARIA team used satellite data acquired on Sept. 2, 2019, to map flooding in the Bahamas in the wake of Hurricane Dorian.

The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory in Pasadena, California, in collaboration with the Earth Observatory of Singapore (EOS), created this flood map depicting areas of the Bahamas that are likely flooded (shown by light blue pixels) as a result of Hurricane Dorian. The map was derived from synthetic aperture radar (SAR) data acquired on Sept. 2, 2019, by the European Union's Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA). The map covers an area of 109 miles by 106 miles (176 kilometers by 170 kilometers) shown by the large red polygon. Each pixel measures about 32 yards (30 meters) across. This map can be used as guidance to identify areas that are likely flooded, and may be less reliable over urban and vegetated areas.

The image contains modified Copernicus Sentinel data (2019) processed by ESA and analyzed by NASA, JPL-Caltech, ARIA, and EOS. This work was funded by NASA along with the Earth Observatory of Singapore and a Singapore National Research Foundation Investigatorship.
