Building Footprints Across Guinea-Bissau from OpenStreetMap

Guinea-Bissau building footprints exported from OpenStreetMap. The data includes every feature tagged as a building, from residential homes to hospitals, schools, and places of worship. It was compiled by the Humanitarian OpenStreetMap Team (HOT) and last updated on 2026-05-15.

Use Cases

• Population estimation based on building density and type.
• Damage assessment for disaster response using building footprint data.
• Urban planning analysis based on the spatial distribution of structures.
• Infrastructure planning based on the locations of hospitals and schools.

Strengths

• Includes all OpenStreetMap features tagged as a building (`building=*`).
• Covers a specific geographic region: Guinea-Bissau.
• Available in multiple geospatial file formats: GEOPACKAGE, SHP, JSON.

Limitations

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