Copper Fire, Los Angeles
County, California
7 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. False-color
images shown here depict the apparent surface temperature (in
Celsius) as estimated from radiance and a simple black-body model.
Warmer tones represent recent or active combustion; areas of gray
are cooling ash or warm bare ground. Low temperatures of unburned
forest and cool ground are shown in green. Images have been geographically
referenced. Vertical exaggeration in 3-d views is 1.5 to one unless
otherwise noted.

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). |
