3/31/2008 ESM 266 1 Remote Sensing: The Major Source for Large Scale Environmental Information Jeff Dozier Emphasis: understand the principles of acquiring and interpreting data from satellite-based remote sensing systems Basic physics Available sensors and products Environmental applications through image analysis Observations from space Sun-synchronous polar orbits – Global coverage, fixed crossing, repeat sampling – Typical altitude 500-1,500 km Low-inclination, non-Sun-synchronous orbits – Tropics, mid-latitudes, varying sampling – Typical altitude 200-2,000 km Geostationary orbits – Regional views of full Earth disk, continuous coverage – Over Equator only, altitude 35,000 km Observations from aircraft and ground • Aircraft
