Useful for

Use cases llm-inferred: BNG habitat baseline screening using annual embedding features across a site and its surroundings · Land-surface change screening for catchment or site context, 2017 to 2025, in FRA or drainage desk studies · Training or feature inputs for GIS-based land-cover classification of study areas
Audience llm-inferred: GIS analysts · ecologists · hydrologists · planners

Limitations

Constraints docs-verified: Unofficial copy, not officially supported by Google · Bottom-up COG orientation: use the provided VRTs for anything beyond simple visualisation · Raw int8 values must be de-quantised before analysis; -128 marks masked pixels · Annual data only, 2017 to 2025 · No area metadata in files; use the index to locate coverage
