Landsat Processing Systems
Landsat Level-1 data products are produced by the Landsat Product Generation System (LPGS). LPGS also generates the 16-bit Quality Assessment Band (QA) and an angle coefficient file that are included in the Level-1 product, as well as a Full Resolution Browse (FRB) and an 8-bit Quality Image. The system then delivers the data products and images to the online cache for distribution.
