U.S. ArmySatellite images typically cover large areas and so are useful for
giving the 'big picture.' The images are taken as a digital recording and
often record wavelengths that the eye cannot see. These images can be tuned
to display a wide variety of earth information.
Small white patches are dry lakes (playas); yellowish brown areas are
mostly disturbed land with little vegetation. Dark and light grays represent
two basic kinds of bedrock (both granite but with different characteristics)
and the alluvial materials eroded from those bedrock sources. Two large
dark areas on the upper and lower right side of the image are the Avawatz
and Soda Mountains, respectively, and their alluvial fans.
This TM image can be 'tuned' to better display different rocks. Examples done by Louisiana State
University.
