On October 24, NASA began mapping the wildfires in California using a new thermal-imaging sensor onboard an unmanned aerial vehicle. The images in this slide show were taken using the 12-channel spectral sensor, and the data was automatically processed onboard the aircraft, then sent to ground stations where it was incorporated into a Google Earth map. The data is displayed in an array of colors (use the legend as a guide): the fire's hot, active spots are yellow; warm areas that were recently burned are shades of red; and areas that are cooling are blue. Shown here is a 3-D view of a fire in San Clemente.
