TerraLook : Watching the Planet Change



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.

The images document the changes near the confluence of the Iguazú and Paraná Rivers, which separate Argentina, Brazil and Paraguay.
