Global Landsat 8-9 Satellite Imagery and Derived Products

Worldwide data products from the Landsat 8 and 9 missions, accessible since each mission's start. The collection, provided by the ESA via the USGS EarthExplorer platform, includes Level 1, Level 2, and Level 3 products. These range from calibrated imagery to higher-level biophysical products like surface water extent and burned area.

Use Cases

• Classify land cover types using calibrated Level 1 imagery and derived surface reflectance products.
• Monitor environmental changes over time by analyzing time-series data of surface water extent and burned area products.
• Estimate surface temperature and evapotranspiration for climate and agricultural studies using Level 2 and Level 3 products.
• Map snow cover dynamics and assess water resources with the dedicated snow cover biophysical product.

Strengths

• Collection 2 features major improvements including enhanced geolocation accuracy and radiometric calibration.
• Provides a global spatial coverage for consistent worldwide analysis.
• Includes multiple processing levels from raw data to higher-level biophysical products.

Limitations

• Specific row counts, file sizes, and temporal resolution details are unknown.
• The dataset's update frequency and recency of the latest data are unspecified.
• License terms for use and redistribution are not provided.
