The 2002 Winter Olympics are hosted by Salt Lake City at several venues
within the city, in nearby cities, and within the adjacent Wasatch
Mountains. This 3-D perspective view, in simulated natural colors,
presents a late spring view over Salt Lake City towards the snow-capped
Wasatch Mountains to the east. The image was created by draping Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER)
image data over digital topography data from the US Geological Surveys
National Elevation Data.
This image was acquired on May 28, 2000, by ASTER on NASAs Terra
satellite. With its 14 spectral bands from the visible to the thermal
infrared wavelength region and its high spatial resolution of 15 to 90
meters of about 50 to 300 feet, ASTER will produce images of the Earth for the next six
years to map and monitor the changing surface of our planet.
ASTER is one of five Earth-observing instruments launched December
18, 1999, on NASAs Terra satellite.
The instrument was built by Japans
Ministries of Economy, Trade and Industry.
The broad spectral coverage and high spectral resolution of ASTER
will provide scientists in numerous disciplines with critical
information for surface mapping and monitoring 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
