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.

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
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
