Blue Cut Fire, San Bernardino National Forest
20 June 2002

As viewed by the FireMapper™ Thermal-Imaging Radiometer

Images were collected from the PSW Airborne Sciences Aircraft and disseminated in part by satellite communications in near-real time. FireMapper measures the radiance of emitted thermal-infrared light, which readily penetrates smoke. Bright areas shown here are very hot ground associated with active fire fronts. Images have been geographically referenced. Vertical exaggeration in 3-d views is 1.5 to one unless otherwise noted.

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