{ "currentVersion": 10.91, "serviceDescription": "Summary:\n\nThe Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology, both in Pasadena, California, created this Damage Proxy Map (DPM) depicting areas that are likely damaged caused by the recent major earthquakes in Puerto Rico in January 2020. \n\nThe map was derived from synthetic aperture radar (SAR) images from the Copernicus Sentinel-1 satellites, operated by the European Space Agency (ESA). The images were taken before and after (January 9, 2020) the sequence of earthquakes.The color variation from yellow to red indicates increasingly more significant surface change. This damage proxy map should be used as guidance to identify damaged areas, and may be less reliable over vegetated areas. For example, the scattered colored pixels over vegetated areas may be false positives, and the lack of colored pixels over vegetated areas does not necessarily mean no damage.\n\nSuggested Use:\nThis damage proxy map shows surface change with yellow to red indiciating more significant change due to the recent earthquakes. The damage proxy map should be used as guidance to identify damaged areas and may be less reliable over vegetated areas. The lack of colored pixels over vegeated areas does not necessarily mean no damage.\n\nSatellite/Sensor:\nCopernicus Sentinel-1 Sythetic Aperture Radar (SAR)\nResolution: 30 meters\n\nCredits:\nContains modified Copernicus Sentinel data, processed by ESA. Analyzed by the NASA-JPL/Caltech ARIA team.
