The U.S. Geological Survey (USGS), in cooperation with the National
Aeronautics and Space Administration (NASA), is pleased to announce the
release of the TerraLook data product. A TerraLook product is a
user-specified collection of JPEG images created from Advanced
Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images
from the NASA Land Processes Distributed Active Archive Center, and
Tri-Decadal Global Landsat Orthorectified images from the USGS archive.

TerraLook will serve GIS, natural resource management, education, and
other communities, and provide easily accessible remotely-sensed data.
TerraLook images are designed for visual interpretation and display, and
are of value to anyone who wants to see the changes to the Earth's
surface over the last 30 years.
