What's in it

Data offered docs-verified: building footprints (polygons) · building height estimates (metres)
Coverage docs-verified: Global · Derived from imagery dated 2014 to 2025, varying by tile and release
Resolution docs-verified: Vector polygons (building footprints). Imagery resolution not stated.
Update frequency docs-verified: Irregular incremental releases; latest dataset refresh 2026-08-13
Formats docs-verified: GeoJSONL (line-delimited GeoJSON, gzipped with .csv.gz extension)
Access docs-verified: Free download and use, no auth stated. Licence per docs: CDLA Permissive 2.0. Entry metadata says ODbL, which conflicts with the docs.

Useful for

Use cases llm-inferred: Impervious area proxy from building footprints for drainage strategy and runoff estimates · Count and footprint area of buildings within a modelled flood extent for FRA exposure screening · Building height screening for massing and context in civils and planning desk studies
Audience llm-inferred: GIS analysts · flood consultants · drainage engineers · hydrologists · planners · BIM/civils engineers

Limitations

Constraints docs-verified: Footprints and heights are model-derived from satellite imagery, not surveyed; quality varies by place · No UK-specific validation stated; verify locally before use in formal submissions · Height estimates are -1 where no estimate exists · Imagery dates vary by tile, so the data is not temporally uniform · Licence conflict: entry metadata says ODbL, docs say CDLA Permissive 2.0 · Hosting moved on 2026-07-24; older links are not moved
