How long will the Pre-Collection data sets remain available?


Pre-Collection datasets will be retained for sometime after each dataset is completely reprocessed into Collection 1 (specific timeframe is yet to be determined). Announcements will be made to alert users when each dataset has completed Collection 1 processing and when the Pre-Collection datasets will be removed.

The Landsat Collections Web page contains the details about all aspects of the Collection 1 effort.


Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
