July 23, 2014 - Ground Control Point (GCP) versioning to be added to Landsat Metadata (MTL) file

The version number of the GCPs used to register an image will be recorded in the MTL file following the next processing system release in September 2014. The Landsat Project is in the process of improving the ground control points (GCPs) used to georegister Landsat products. (Read More)

July 9, 2014 - Landsat Metadata (MTL) File Changes

The Metadata (MTL) file distributed with the Level-1 data products will be changing in September 2014, to remove padding from the end of the file. This change will remove the extra lines that are currently at the end of the file, which was historically used to distribute a fixed-size MTL to support the HDF4 format. Since GeoTIFF is now the only data format provided, the bytes at the end of the file, the extra lines will be removed. Samples of the modified MTL files are available to download: .zip (4.77 KB)

April 25, 2013 - Old Metadata Format to be Removed

For over 6 months, Landsat 1-7 products have included a new metadata format to align with operational data from the Landsat Data Continuity Mission. We have been including the historic metadata format to allow users enough transition time to adjust to the new format. That file, *_OLD.txt, will be removed as of Monday, April 29, 2013.
