# Landsat Collection 2 Level-2 Surface Reflectance
*data products*

## Specifications
- **level**: L2
- **distributor**: usgs
- **spectral range nm**: {"min":430,"max":2350}
- **spectral band count**: 7
- **gsd m**: {"native":30}
- **file format**: Cloud Optimized GeoTIFF
- **access endpoint**: https://earthexplorer.usgs.gov
- **access model**: open
- **licence**: USGS public domain (no restrictions on use or redistribution)
- **primary data portal url**: https://earthexplorer.usgs.gov
- **use cases**: ["Canonical multispectral surface-reflectance input for long-term forest change monitoring","Foundation for GLAD-L deforestation alerts and the Hansen Global Forest Change dataset","Annual deforestation mapping (PRODES uses Landsat as primary input)","Cross-sensor time series back to 1982 (longest continuous multispectral land archive)","REDD+, VCM, and EUDR baseline reflectance for forest cover analytics"]
- **practical limitations**: ["Band count and spectral range differ by sensor generation (6 bands 450 to 2350 nm for TM/ETM+; 7 bands 430 to 2290 nm for OLI/OLI-2)","LEDAPS atmospheric correction (Landsat 4 to 7) vs LaSRC (Landsat 8 and 9) introduces an algorithm discontinuity for cross-sensor time series","Landsat 7 ETM+ scan line corrector failure (May 2003) introduces about 22 percent data gaps in all post-2003 ETM+ scenes; gap-fill is the user's responsibility","Processing constraint requires solar zenith angle below 76 degrees; high-latitude winter coverage limited","30 m GSD insufficient for sub-hectare disturbance detection (use Sentinel-2 or commercial high-resolution for finer scale)"]
- **known artefacts**: ["BOA reflectance is a synonym sometimes used by lower-tier aggregators; USGS canonical term is Surface Reflectance","OLI scene contains 11 bands total (OLI plus TIRS) but the SR product distributes only the 7 reflective bands (panchromatic, cirrus, and thermal excluded)"]
- **last verified date**: "2026-05-18T00:00:00.000Z"
- **verified by**: agency-doc
