Blue Cut Fire, San Bernardino National Forest (June 20, 2002):
As viewed by the FireMapper Thermal-imaging Radiometer aboard the Pacific Southwest Research Station's Airborne Sciences Aircraft
Images were collected from the PSW Airborne Sciences Aircraft. Shown is energy emitted from the ground as measured at thermal-infrared wavelengths by the PSW FireMapper system. Bright areas are very hot ground associated with active fire fronts. Images have been geographically referenced and are depicted on USGS 7.5-minute quadrangles, or on a digital elevation model derived from the Space Shuttle topographic mapping mission.

Blue Cut Fire as viewed from above in thermal-infrared light (11.5 to 12.3 micrometers wavelength).

Lines in blue and purple or black are streams and roads from topo map layer.

Light gray tones are areas of ash warmed by solar heating. Dark gray tones are unburned vegetation. Apparent temperatures of residual burning and spot fires (red, orange, and yellow regions) are color coded according to the key. Active flaming combustion is shown in yellow. Latitude and longitude of hot spots may be obtained by opening the TIFF file in a suitable viewer such as Erdas Imagine. Ash surface temperatures may be indicative of the severity of burning.

After downloading a TIFF as a zip file, decompress it with WinZip (or your favorite ZIP utility) and the TIFF will be viewable in WangIMG or other graphics viewer. Included are the auxiliary files necessary for proper geo-referencing (if the viewer has that capability).
