Las Vegas metropolitan area has suffered enormous change during the past decades. The images below are provided by NASA and show the development  of this region from 1985 until 2009. “On March 1, 2009, NASA’s Landsat 5 satellite turned 25. These images of the western portion of the Las Vegas metropolitan area show the city’s steady spread into the adjacent desert landscape. Undeveloped land appears along the left edges of the top two images. Here, the land on the city’s outskirts appears in shades of beige and tan, with just a hint of the street grid to come. By 1989, however, development filled the upper left corner—a residential area, complete with curving roads and semicircle streets. In subsequent images, development spreads southward, and by 2004, the entire image shows cityscape, including Interstate 215 passing through southwestern portion of the city.” Impressive or what?  (photos and text courtesy of NASA’s Earth Observatory )
