Great Sandy Desert
In a small corner of the vast Great Sandy Desert in Western Australia,
large sand dunes -- the only sand in this desert of scrub and rock --
appear as lines stretching from top to bottom. The light-colored fan shapes
are scars from wildfires.
This image was acquired by Landsat 7's Enhanced Thematic Mapper plus (ETM+)
sensor on August 22, 2000. This is a false-color composite image made using near
infrared, red, and blue wavelengths. The image has also been sharpened using the
sensor's panchromatic band.
