The 40-by-50 kilometer damage proxy map, which covers a region near Tacloban City, where the massive storm made landfall, was processed by JPL’s Advanced Rapid Imaging and Analysis (ARIA) team using X-band interferometric synthetic aperture radar data from the Italian Space Agency’s COSMO-SkyMed satellite constellation. The technique uses a prototype algorithm to rapidly detect surface changes caused by natural or human-produced damage. The assessment technique is most sensitive to destruction of the built environment. When the radar images areas with little to no destruction, its image pixels are transparent. Increased opacity of the radar image pixels reflects damage, with areas in red reflecting the heaviest damage to cities and towns in the storm’s path. The time span of the data for the change is Aug. 19–Nov. 11, 2013. Each pixel in the damage proxy map is about 30 meters across. Read more.
