Landsat 5 urban sprawl Image of a portion of the Magdalena Valley in Colombia, South America, transmitted by Landsat (formerly ERTS) 2 on Jan. 7, 1977. Green, red, and infrared are recorded separately by the satellite and then combined to make the image. Vegetation appears red, and barren land is green. The Magdalena River and nearby lakes are blue; white splotches are clouds. The roughly parallel north-south pattern along the centre right indicates rock outcrops where the rocks have been bent into a folded structure. Landsat 2 was launched Jan. 22, 1975.
