SummaryWeather satellites available from the early 1960s

forward, but of low spatial and spectral resolutionEarth resources remote sensing began with the launchof Landsat-1 in 1972; the U.S. was the leader. Landsatwas the only show in town through the early 1980s.Other countries entered the Earth resources race in the

mid-1980s (e.g., France and the SPOT satellite)SPOT began the trend of installing a panchromatic bandwith very high spatial resolution, to be followed bynumerous others and culminating in the one-meter classsystems of the late 1990s

The 1990s to the present saw the emergence of private-sector companies in the satellite-launch andoperationsmarket (e.g., Space Imaging > GeoEye, Digital Globe)Today, there are innumerable Earth-observing satellitesin orbit, including government / civilian / academic-orientedsystems, private-sector systems, and military
