Building Footprints Across Gambia from OpenStreetMap

OpenStreetMap exports contain every feature tagged as a building across Gambia, including residential homes, hospitals, schools, and places of worship. The Humanitarian OpenStreetMap Team (HOT) provides this data, last updated on 2026-05-15. Completeness varies by region, with urban areas typically well-mapped and remote areas potentially incomplete.
