The USGS Landsat 1 MSS Collection 2 provides access to raw satellite imagery, categorized into Tier 1 and Tier 2 based on data quality.
-
Tier 1 data represents the highest quality, suitable for time-series analysis and includes Level-1 Precision Terrain (L1TP) processed scenes.
-
Tier 2 data encompasses scenes that did not meet Tier 1 criteria, such as L1GT and L1GS processed scenes, and may be used when Tier 1 is unavailable.
-
Both Tiers offer DN values, representing scaled, calibrated at-sensor radiance captured by the Landsat 1 MSS instrument.

USGS Landsat 1 MSS Collection 2 Tier 1 Raw Scenes
Landsat 1 MSS 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 … c2 global l1 landsat lm1 mss -
USGS Landsat 1 MSS Collection 2 Tier 2 Raw Scenes
Landsat 1 MSS 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. This includes Systematic terrain (L1GT) and Systematic (L1GS) processed scenes, as well as any L1TP scenes that do … c2 global l1 landsat lm1 mss
