ARIA Damage Proxy Map (Copernicus Sentinel-1) on 9/2/19 for Hurricane Dorian

Date of Image: 9/2/2019 Date of Next Image: Unknown Summary: The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology in Pasadena, California, created this Damage Proxy Map (DPM) depicting areas of the Bahamas that are likely damaged (shown by red and yellow pixels) as a result of Hurricane Dorian that made a landfall as Category 5 storm Sunday (September 1) afternoon. The map was derived from synthetic aperture radar (SAR) data acquired around 7pm (local time) on September 2, 2019 by the European Union's Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA). The pre-event images were taken before (August 21, 2019) and the post-event image was acquired a day after the hurricane's landfall. Suggested Use: The color variation from yellow to red indicates increasingly more significant ground surface change. This damage proxy map should be used as guidance to identify damaged areas, and may be less reliable over vegetated areas and flooded areas. For example, the scattered single colored pixels over vegetated areas may be false positives, and the lack of colored pixels over vegetated areas does not necessarily mean no damage.
