Building Footprints Across Mali from OpenStreetMap

OpenStreetMap volunteer mappers have tagged every building feature across Mali, from homes to hospitals and schools. The dataset is useful for population estimation, damage assessment, and urban planning. Coverage reflects mapper activity, with urban areas usually well-represented and remote areas potentially sparse.

Use Cases

• Estimate population distribution based on building density and type.
• Assess disaster damage by comparing pre- and post-event building footprints.
• Plan urban development and infrastructure projects using building location data.
• Analyze the distribution of public facilities like schools and hospitals.

Strengths

• Includes all OpenStreetMap features tagged `building=*`, covering a wide range of building types.
• Available in multiple geospatial formats including GEOPACKAGE, SHP, and JSON.
• Last updated on 2026-06-23, suggesting recent maintenance.

Limitations

• Coverage is uneven, with urban areas well-represented and remote areas likely sparse.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
