The LANDSAT 7 satellite aquired this true-color image near the Hanford Nuclear Reservation
on July 9, 2000, two weeks after a brushfire swept through 100,000 acres of
scrubland. LANDSATs Enhanced Thematic Mapper Plus views the Earth at much
higher resolution than the Geostationary Operational Environmental Satellite
(GOES) Imager or Multi-angle
Imaging Spectroradiometer (MISR). Each instrument has different strengths. LANDSAT
has up to 15 meter resolution, compared to GOESs 1 kilometer resolution and
MISRs 275 meter resolution. GOES can view the same area of the Earth as
frequently as once a minute, while LANDSAT is limited to once every 16 days. MISR
is unique because it views the Earth at 9 different angles simultaneously. Combined
with other Earth observing sensors, these instruments are providing us with a
new view of the world that is leading us towards a new understanding.
