Building Footprints Across Madagascar from OpenStreetMap

OpenStreetMap exports provide building footprints across Madagascar, including residential homes, hospitals, schools, and places of worship. The Humanitarian OpenStreetMap Team (HOT) compiled this data, which was last updated on 2026-05-14. Completeness varies by region, with urban areas likely being more thoroughly mapped than remote locations.

Use Cases

• Estimate population distribution based on building density and type.
• Assess damage from natural disasters by comparing pre- and post-event building footprints.
• Plan urban infrastructure development based on the location of schools, hospitals, and residential areas.

Strengths

• Includes a variety of building types such as residential homes, hospitals, schools, and places of worship.
• Data is available in multiple geospatial file formats including GEOPACKAGE, SHP, and JSON.

Limitations

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