A Desert City Blooms
In the 25 years that Landsat 5 has been in orbit, the desert city of Las Vegas has gone through a massive growth spurt. The outward expansion of the city is shown here with a series of false-color images. The dark purple grid of city streets and the green of irrigated vegetation grow out in every direction into the surrounding desert. These images were created using reflected light from the shortwave infrared, near-infrared, and green portions of the electromagnetic spectrum (Landsat 5 TM bands 7,4,2).
