Summary:
The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory (JPL) and California Institute of Technology (Caltech) in Pasadena, California, created this Damage Proxy Map (DPM) depicting areas in Providencia Island that are likely damaged (shown by red and yellow pixels) as a result of Hurricane Iota. The map was derived from Synthetic Aperture Radar (SAR) data acquired around on November 22, 2020 by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA).
The map covers the entire island, and each pixel measures about 30 meters across. The color variation from yellow to red indicates increasingly more significant ground surface change. Media reports provided anecdotal preliminary validation. 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.
Suggested Use:
