Building Footprints Across Tonga from OpenStreetMap

OpenStreetMap exports provide building footprints across Tonga, including every feature tagged as a building. The Humanitarian OpenStreetMap Team (HOT) compiled this data, which was last updated on 2026-05-15. Completeness varies by region, with urban areas typically well-mapped and remote areas potentially incomplete.

Use Cases

• Estimate population density based on building distribution.
• Assess building damage after natural disasters based on footprint data.
• Plan urban infrastructure and services based on building locations and types.

Strengths

• Includes a wide range of building types, from residential homes to hospitals, schools, and places of worship.
• Data is available in multiple geospatial formats, including GEOPACKAGE, SHP, and JSON.

Limitations

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