Google Open Buildings

Google's Open Buildings is an open access dataset containing the geometry of buildings across most of Africa, South Asia and South-East Asia. This version of the dataset is transformed to be partitioned by admin 1 boundaries and available in cloud-native geospatial formats (PMTiles, GeoParquet). Note that https://source.coop/repositories/vida/google-microsoft-osm-open-buildings/description is likely a better source for this data. There is no commitment to keep this dataset up to date with the la

What's in it

Data offered docs-verified: building footprint polygons · per-building confidence score · Plus Code of building centre · area_in_meters attribute · country_iso · quadkey
Coverage docs-verified: Africa, South Asia, South-East Asia, Latin America and the Caribbean
Update frequency docs-verified: No committed update schedule; not guaranteed to track the latest source releases
Formats docs-verified: GeoParquet · PMTiles
Access docs-verified: Public; anonymous HTTPS and S3 access via data.source.coop; licensed CC BY-4.0 or ODbL v1.0 (user may choose)

Useful for

Use cases llm-inferred: Building footprint exposure screening for flood risk assessments in covered African and South/South-East Asian catchments · Building footprint counts and impervious-area proxies for drainage strategy runoff estimates in covered regions · Desk-based building constraint mapping for civils and planning studies in covered regions, previewed via PMTiles
Audience llm-inferred: flood consultants · drainage engineers · GIS analysts · planners

Limitations

Constraints llm-inferred: Covers Africa, South Asia, South-East Asia, Latin America and the Caribbean only; no UK or European coverage · Geometry only: no building type, street address or other attributes beyond confidence and Plus Code · No commitment to keep up to date with latest releases · Docs state another source is likely better: https://source.coop/repositories/vida/google-microsoft-osm-open-buildings/description · Entry regions field says Global, which conflicts with the documented coverage areas · Large downloads: PMTiles file is 121.61 GB
