AI-generated Key Takeaways
-
This page provides access to USGS Landsat 8 Collection 2 datasets, including Tier 1 and Tier 2 Raw Scenes, as well as Tier 1 and Real-Time data in both Raw and Top-of-Atmosphere (TOA) Reflectance formats.
-
Landsat 8 Collection 2 Tier 1 data represents the highest quality scenes suitable for time-series analysis and includes Level-1 Precision Terrain (L1TP) processed data.
-
Landsat 8 Collection 2 Tier 2 data contains scenes that did not meet Tier 1 criteria and includes Systematic Terrain (L1GT) and Systematic (L1GS) processed scenes.
-
Real-Time data is available for Tier 1 scenes in both raw Digital Number (DN) values and calibrated TOA reflectance.
-
All datasets provide global coverage and are calibrated to at-sensor radiance or reflectance.

USGS Landsat 8 Collection 2 Tier 1 Raw Scenes
Landsat 8 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 l8 landsat lc8 oli-tirs -

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
