Google-Microsoft-OSM Open Buildings - combined by VIDA

This dataset merges Google's V3 Open Buildings, Microsoft's GlobalMLFootprints, and OpenStreetMap building footprints. It contains 2,705,459,584 footprints and is divided into 200 partitions. Each footprint is labelled with its respective source, either Google, Microsoft, or OpenStreetMap. It can be accessed in cloud-native geospatial formats such as GeoParquet, FlatGeobuf and PMTiles.

What's in it

Data offered docs-verified: building footprints · footprint source label (Google, Microsoft or OpenStreetMap)
Coverage llm-inferred: Global · Source snapshots: Google 2023-10-02, Microsoft 2024-05-28, OpenStreetMap 2024-05-28 (Microsoft imagery 2014-2023)
Update frequency llm-inferred: No fixed schedule stated; combined release 2.0 dated 2024-09-04; page last updated 21 Aug 2025
Formats docs-verified: GeoParquet · FlatGeobuf · PMTiles
Access docs-verified: Public; anonymous HTTPS/S3 access via data.source.coop; licence ODbL v1.0

Useful for

Use cases llm-inferred: Building exposure counts within a flood extent for FRA screening · Impervious-area inputs from footprint totals for drainage strategy estimates · Desk-based constraints mapping of building footprints for civils site feasibility
Audience llm-inferred: flood consultants · drainage engineers · GIS analysts · planners

Limitations

Constraints llm-inferred: Google component covers only its inference area (Africa, South Asia, South-East Asia, Latin America and Caribbean); UK coverage is not stated in the docs · Footprints carry only geometry and a few fields: no building type, address or attributes beyond source and confidence · Microsoft footprints have null confidence values · Source snapshots date from 2023-10-02 to 2024-05-28 (Microsoft imagery 2014-2023), so may not reflect current buildings · Docs conflict on partition count: 200 in the overview vs 182 root partitions in the Partitioning section · Schema lists bf_source as Google or Microsoft only, although OpenStreetMap footprints are also labelled · Very large dataset (4.8 TB served per docs analytics); query by country or S2 partition rather than the whole file · Partition country_iso=None holds geometry for unnamed boundaries (e.g. Abyei) · ENTRY licence says 'see product README' while DOCS state ODbL v1.0; confirm before commercial reuse · ODbL carries attribution and share-alike obligations
