Building Footprints for Réunion from OpenStreetMap

OpenStreetMap exports provide building footprints across Réunion, including every feature tagged as a building. The Humanitarian OpenStreetMap Team (HOT) maintains this export, last updated on 2026-05-14. Completeness of the data varies by region, with urban areas likely being better mapped than remote areas.

Use Cases

• Population estimation based on building density and type.
• Damage assessment for disaster response using building footprint data.
• Urban planning and infrastructure development analysis leveraging geospatial building locations.
• Cross-referencing local field knowledge with volunteered geographic information for validation.

Strengths

• Includes all OpenStreetMap features tagged as a building, covering types from residential homes to hospitals and schools.
• Data is provided in multiple geospatial file formats (GEOPACKAGE, SHP, JSON) for flexibility.
• Maintained by the Humanitarian OpenStreetMap Team (HOT), a recognized organization in the field.

Limitations

• Completeness varies by region; remote areas may be incomplete.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
