Landsat imagery held in the USGS archives can be searched on the following pages:
Many scenes are ready for immediate download from the websites listed above; requests can be placed for processing of scenes not downloadable, using these same websites. Once requests are placed and imagery is processed, an email notification is returned with the direct download location. Processing generally takes 1-3 days.
Imagery not found in the USGS archive may have been collected by the USGS International Cooperator (IC) ground stations. Each station is the primary source of distributing data collected at their location. Details on the IC network can be found at http://landsat.usgs.gov/about_ground_stations.php.
Before downloading Landsat data, it is important to understand that a number of files will be included, and how the individual band files work together in image processing software to create a final RGB color image. Please see these pages for more details:
The Landsat Processing Details page provides information on parameters, correction levels and systems used during data processing.
