April 21, 2008 - Imagery for Everyone
By February 2009, any Landsat archive scene selected by a user will be processed, at no charge, automatically to a standard product recipe and staged for electronic retrieval.
In addition, newly acquired scenes meeting a cloud cover threshold of 20% or below will be processed to the standard recipe and placed online for at least three months, after which they will remain available for selection from the archive.
The USGS Landsat archive is an unequaled 35-year record of the Earth’s surface that is valuable for a broad range of uses, ranging from climate change science to forest management to emergency response, plus countless other user applications.
