AI-generated Key Takeaways
-
This page features various USGS Landsat 8 Collection 2 datasets, including Tier 1 and Tier 2, offering both raw Digital Numbers (DN) and Top-of-Atmosphere (TOA) reflectance.
-
Landsat 8 Collection 2 Tier 1 data represents the highest quality scenes suitable for time-series analysis, including real-time data for immediate use.
-
Tier 2 data comprises scenes that did not meet Tier 1 criteria but still provide valuable information for less critical applications.
-
All datasets offer global coverage and are processed to Level-1 Precision Terrain (L1TP), Level-1 Systematic Terrain (L1GT) or Level-1 Systematic (L1GS) standards, depending on the dataset and individual scene.

USGS Landsat 8 Collection 2 Tier 1 and Real-Time data TOA Reflectance
Landsat 8 Collection 2 Tier 1 and Real-Time data calibrated top-of-atmosphere (TOA) reflectance. Calibration coefficients are extracted from the image metadata. See Chander et al. (2009) for details on the TOA computation. Landsat scenes with the highest available data quality are placed into Tier 1 … c2 global l8 landsat lc8 satellite-imagery -
USGS Landsat 8 Collection 2 Tier 2 Raw Scenes
Landsat 8 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 not … c2 global l8 landsat lc8 oli-tirs
