The Landsat Collection 2 Level-1 product metadata (MTL.txt) file includes a SATURATION_BAND_ x
parameter for each Landsat band. This field indicates the presence of radiometric saturation for each band
in every Landsat scene.

Data that is processed to meet Collections specifications has a Landsat Product Identifier, as opposed to the historical Landsat Scene ID. Along with information inherited from the Scene ID, the Landsat Product Identifier includes the processing level, processing date, collection number, and collection category (bolded below). Scene ID Landsat Product Identifier LXSPPPRRRYYYYDDDGSIVV LXSS_LLL...
Definitive Ephemeris is used for geometrically correcting Landsat data and providing improved accuracy over predicted ephemeris. Learn more (and download DE files): Landsat Definitive Ephemeris
Landsat Calibration Parameter Files (CPFs) provide radiometric and geometric coefficients needed for processing of raw, uncorrected Landsat image data into Level-1 data products. Over 15,000 coefficients are issued to span distinct timeframes and are updated with improved calibration coefficients. CPFs are often updated with improved coefficients. Learn more (and search CPF files): Landsat...
Landsat Bias Parameter Files (BPFs) supply radiometric correction parameters that are applied during Level-1 processing of Landsat data. Learn more (and search for BPF files): Landsat Bias Parameter
Use the senor viewing angle model coefficients in the Landsat Collection 2 Angle Coefficient files to create angle bands and to compute the solar and senor viewing angles on a per-pixel basis. Learn more: Solar Illumination and Sensor Viewing Angle Coefficient Files
Landsat Level-1 data can be rescaled to the top of atmosphere (TOA) reflectance and/or radiance using radiometric rescaling coefficients provided in the metadata file (MTL.txt) that is delivered with the Landsat Level-1 product. The MTL file also contains the thermal constants needed to convert thermal band data to TOA brightness temperature (BT). Formulas for these conversions are at Using the...
The Landsat Collection 1 Level-1 product identifier includes the Collection processing levels, processing date, collection number, and collection tier category: LXSS_LLLL_PPPRRR_YYYYMMDD_yyyymmdd_CC_TX Where: L = Landsat X = Sensor (“C”=OLI/TIRS combined, “O”=OLI-only, “T”=TIRS-only, “E”=ETM+, “T”=“TM, “M”=MSS) SS = Satellite (”07”=Landsat 7, “08”=Landsat 8) LLL = Processing correction level (L1TP...
The sensors onboard each of the Landsat satellites were designed to acquire data in different wavelengths within the electromagnetic spectrum. View Bandpass Wavelengths for all Landsat Sensors The Multispectral Scanner (MSS) carried on Landsat 1,2,3,4 and 5 collected data in four ranges (bands); the Thematic Mapper (TM) sensor on Landsat 4 and Landsat 5 included those bands found on earlier...

This is the third video in a series describing the new U.S. Geological Survey (USGS) Landsat Collection 1 inventory structure. Collection 1 required the reprocessing of all archived Landsat data to achieve radiometric and geometric consistency of Level-1 products through time and across all Landsat sensors.
