These views of western Alaska were acquired by MISR on June 25, 2000
during Terra orbit 2775. The images cover an area of about 150
kilometers x 225 kilometers, and have been oriented with north to the
left. The left image is from the vertical-viewing (nadir) camera, whereas
the right image is a stereo "anaglyph" that combines data from
the forward-viewing 45-degree and 60-degree cameras. This image
appears three-dimensional when viewed through red/blue glasses with the
red filter over the left eye. It may help to darken the room lights when
viewing the image on a computer screen.
The Yukon River is seen wending its way from upper left to lower right.
A forest fire in the Kaiyuh Mountains produced the long smoke plume that
originates below and to the right of image center. In the nadir view, the
high cirrus clouds at the top of the image and the smoke plume are similar
in appearance, and the lack of vertical information makes them hard to
differentiate. Viewing the righthand image with stereo glasses, on the
other hand, demonstrates that the scene consists of several vertically-stratified
layers, including the surface terrain, the smoke, some scattered cumulus
clouds, and streaks of high, thin cirrus. This added dimensionality is one
of the ways MISR data helps scientists identify and classify various
components of terrestrial scenes.
