Kalgoorlie-Boulder is a city in the Goldfields-Esperance region of Western Australia. The town was founded in 1893 when gold was discovered in the so-called "Golden Mile." The area boomed, with an area population of over 200,000; by 1903 Kalgoorlie grew to 30,000, close to its present population. The concentrated area of large gold mines is considered to be the richest square mile on earth. The image was acquired November 26, 2013, covers an area of 20.2 x 21.9 km, and is located at 30.8 degrees south, 121.5 degrees east.

With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and data products.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate, Washington, D.C.
