The LANDSAT 7 satellite aquired this true-color image near the Hanford Nuclear Reservationon July 9, 2000, two weeks after a brushfire swept through 100,000 acres ofscrubland. LANDSAT’s Enhanced Thematic Mapper Plus views the Earth at muchhigher resolution than the Geostationary Operational Environmental Satellite(GOES) Imager or Multi-angleImaging Spectroradiometer (MISR). Each instrument has different strengths. LANDSAThas up to 15 meter resolution, compared to GOES’s 1 kilometer resolution andMISR’s 275 meter resolution. GOES can view the same area of the Earth asfrequently as once a minute, while LANDSAT is limited to once every 16 days. MISRis unique because it views the Earth at 9 different angles simultaneously. Combinedwith other Earth observing sensors, these instruments are providing us with anew view of the world that is leading us towards a new understanding.
