Datasets tagged c2 in Earth Engine

  • This content describes various Landsat Collection 2 datasets from USGS, including both Tier 1 and Tier 2 scenes for Landsats 1-5 (MSS/TM) and Landsats 7-9 (various instruments).

  • Tier 1 scenes represent the highest available data quality and are suitable for time-series analysis, often processed with Level-1 Precision Terrain (L1TP).

  • Tier 2 scenes are those that do not meet Tier 1 criteria and include Systematic terrain (L1GT) and Systematic (L1GS) processed data.

  • The datasets provide scaled, calibrated at-sensor radiance (DN values) or calibrated top-of-atmosphere (TOA) reflectance, with calibration details derived from image metadata and external references.

  • Some Landsat 7 and 8 datasets also include real-time (RT) data in addition to Tier 1 scenes.
