Return to Landsat Quality Assessment Band Information


Quality Assessment (QA) bands are helpful for evaluating the overall usefulness of a Landsat pixel. Each pixel in the QA band contains an integer value that represents bit packed combinations of surface, atmospheric, and sensor conditions that can affect the individual pixel quality.

QA bands are currently provided with Landsat Level-1 and Landsat Level-2 Surface Reflectance data products.
