Kathmandu, Nepal

Kathmandu is the capital of Nepal, with a population of about 2.5 million inhabitants for the greater metropolitan area. The city is the gateway to tourism in Nepal, and is the center of the country's economy, with a literacy rate of 98%. The Kathmandu Valley is listed as a UNESCO World Heritage Site to recognize the rich number of monuments found in seven different monument zones. The image was acquired March 4, 2009, covers an area of 22 by 22 km, and is located at 27.6 degrees north latitude, 85.3 degrees east longitude.

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.
