Summary[edit]
DescriptionLandsat View, Tehran, Iran - Flickr - NASA Goddard Photo and Video.jpg |
Between 1985 and 2009, the population of Tehran, Iran, grew from six million to just over seven million. The city's growth was spurred largely by migration from other parts of the country. In addition to being the hub of government and associated public sector jobs, Tehran houses more than half of Iran's industry. Landsat 5 acquired these false-color images of Tehran on August 2, 1985, and July 19, 2009. The city is a web of dark purple lines, vegetation is green and bare ground is pink and tan. The images were created using both infrared and visible light (band combination 7, 4, and 2) to distinguish urban areas from the surrounding desert. NASA and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images that is freely available over the Internet. The next Landsat satellite, now known as the Landsat Data Continuity Mission (LDCM) and later to be called Landsat 8, is scheduled for launch in 2013. In honor of Landsat’s 40th anniversary in July 2012, the USGS released the LandsatLook viewer – a quick, simple way to go forward and backward in time, pulling images of anywhere in the world out of the Landsat archive. NASA Goddard Space Flight Center enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics. Goddard plays a leading role in NASA’s accomplishments by contributing compelling scientific knowledge to advance the Agency’s mission. |
