This Advanced Spaceborne Thermal Emission and Reflection Radiometer
(ASTER) sub-scene was acquired on May 20, 2000 and shows an area along
the west side of the Cascade Range in west central Oregon. (the full image measures 39 by
47 km) Bands 4 (shortwave infrared), 3 (near infrared), and 2 (red) were
combined as red, green, and blue. In this composite, snow appears blue,
forests are green, and clear-cut areas are orange-pink. The magnitude of
logging operations is quite obvious, appearing as a checker board
The braided streams of the Betsiboka Estuary have largely returned to their normal size, leaving puddles of blue and green water to show the extent of earlier flooding. Tropical Cyclone Gafilo moved across Madagascar on March 7 and 8, dumping heavy rain in its path. As time passed, the waters eventually flowed down the rivers to the coast, flooding the low-lying land in the west. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra satellite captured this image of the estuary on March 20, 2004. The false-color image uses green, red, and near-infrared light (ASTER bands 3, 2, 1) so that the main river is green, other water is blue, and vegetation is red.
