Along with the new Landsat Product Identifier, new files and additions to metadata are also being implemented and delivered with the Level-1 data products:
NOTE: Adding these files creates a larger Level-1 data product. See this FAQ for a comparison of file sizes between Pre-Collection and Collection 1 data products.
The C Function of Mask (CFMask) algorithm will be used to populate fill, cloud, cloud confidence, cloud shadow, and snow/ice in Landsat 4-5, Landsat 7, and Landsat 8 scenes, and will be populated in the Quality Assessment (QA) band.
Removal of Sensor Chip Assemblies (SCA) overlaps from Band 9 and Band 10
The processing level designations will be changing in Collection 1 Level-1 data products. The table below displays the levels currently used compared to those being implemented for Collection 1 data products.
The Landsat Collections Web page contains the details about all aspects of the Collection 1 effort.
