Building Footprints Across Chad from OpenStreetMap

Chad's building footprints, tagged from residential homes to hospitals, schools, and places of worship. The data is sourced from OpenStreetMap, a free collaborative world map, and was last updated on June 22, 2026. Coverage reflects where volunteer mappers have been active, with urban areas typically well-represented.

Use Cases

• Estimate population distribution based on building density and types.
• Assess damage to infrastructure after disasters using building footprint data.
• Plan urban development and service allocation using the spatial distribution of buildings.
• Cross-reference local field knowledge for critical decision-making in remote areas.

Strengths

• Includes diverse building types such as residential homes, hospitals, schools, and places of worship.
• Available in multiple geospatial file formats including GEOPACKAGE, SHP, and JSON.
• Sourced from OpenStreetMap, a widely-used, collaborative mapping project.

Limitations

• Coverage is uneven, with remote areas likely sparse due to reliance on volunteer mapper activity.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
