USGS Landsat 9 Collection 2 Tier 1 Raw Scenes
Landsat 9 Collection 2 Tier 1 DN values, representing scaled, calibrated at-sensor radiance. Landsat scenes with the highest available data quality are placed into Tier 1 and are considered suitable for time-series processing analysis. Tier 1 includes Level-1 Precision Terrain (L1TP) processed data that have … c2 global l9 landsat lc9 oli-tirs -
USGS Landsat 9 Collection 2 Tier 2 Raw Scenes
Landsat 9 Collection 2 Tier 2 DN values, representing scaled, calibrated at-sensor radiance. Scenes not meeting Tier 1 criteria during processing are assigned to Tier 2.
