{ "currentVersion": 10.91, "serviceDescription": "Date of Imagery: \n11/11/2018 02:00 UTC (6:00pm PST) \n\nNext Update: None currently planned \n\nSummary: \nThe Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory in Pasadena, California, created this Damage Proxy Map (DPM) depicting areas of Southern Cailfornia that are likely damaged (shown by red and yellow pixels) as a result of the Woolsey Fire. The map is derived from synthetic aperture radar (SAR) images from the Copernicus Sentinel-1 satellites, operated by the European Space Agency (ESA). The pre-event images were taken before (November 5, 2018) and the post-event image was acquired during the fire (November 11, 2018). The map covers an area of 50 miles x 25 miles (80 km x 40 km), indicated with the big red polygon. Each pixel measures about 33 yards x 33 yards (30 m x 30 m). The color variation from yellow to red indicates increasingly more significant ground surface change. Preliminary validation was done by comparing to the Approximate fire location by the Google Crisismap. 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 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.\n\nSatellite/Sensor:\nSynthetic Aperture Radar (SAR) from Copernicus Sentinel-1 operated by the European Space Agency (ESA); 30 meter resolution\n\nCredits/Acknowledgements:\nSentinel-1 data were accessed through the Copernicus Open Access Hub. The image contains modified Copernicus Sentinel data (2018), processed by ESA and analyzed by the NASA-JPL/Caltech ARIA team. This research was carried out at JPL funded by NASA. \n\nFor more information about ARIA, visit: http://aria.jpl.nasa.gov", "name": "CA_fires_2018/woolsey_aria_dpm_11112018_0200", "description": "Date of Imagery: \n11/11/2018 02:00 UTC (6:00pm PST) \n\nNext Update: None currently planned \n\nSummary: \nThe Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory in Pasadena, California, created this Damage Proxy Map (DPM) depicting areas of Southern Cailfornia that are likely damaged (shown by red and yellow pixels) as a result of the Woolsey Fire.
