What's in it
- Data offered docs-verified
- surface reflectance bands (coastal, blue, green, red, nir08, swir16, swir22) · surface temperature (lwir11, lwir) · atmospheric opacity and transmittance bands · QA masks (cloud, cloud shadow, snow/ice, water, aerosol) · product metadata files (MTL json/txt/xml)
- Coverage docs-verified
- Global · 1982-08-22 to present (open-ended)
- Resolution docs-verified
- 30 m for reflectance, thermal and QA bands (gsd summaries list 30, 60, 100, 120 m)
- Formats docs-verified
- Cloud-Optimized GeoTIFF · STAC JSON (collection and items) · GeoJSON (items) · JPEG (thumbnails and browse images) · text/XML (metadata files)
- Access docs-verified
- No authentication listed in ENTRY. Licence recorded as 'proprietary' in ENTRY, but docs link the USGS data policy titled 'Public Domain'. Conflicting; verify against USGS policy.
Useful for
- Use cases llm-inferred
- Land cover and vegetation (NDVI) change baselines for FRA or habitat assessments using 1980s-onward archive · Surface temperature screening for urban heat or drainage context · Historic land-use and water-body change mapping for contaminated land or BNG baselines
- Audience llm-inferred
- GIS analysts · ecologists · hydrologists · environmental consultants · planners
Limitations
- Constraints llm-inferred
- Spatial resolution is 30 m for most bands, which may be coarse for site-scale work · Sensor changes across Landsat 4-9 (TM, ETM+, OLI/TIRS) require harmonisation for long time series · Cloud and shadow masking needed using QA bands before analysis · Licence wording is inconsistent between ENTRY metadata and docs
