Chile Building Footprints from OpenStreetMap for Urban Analysis

OpenStreetMap exports provide building footprints across Chile, including features tagged as residential homes, hospitals, schools, and places of worship. The Humanitarian OpenStreetMap Team (HOT) maintains this export, last updated on 2026-05-14. Completeness varies by region, with urban areas likely being more complete than remote areas.

Use Cases

• Population estimation based on building density and type.
• Damage assessment for natural disasters based on building footprint locations.
• Urban planning and infrastructure development based on the spatial distribution of buildings.
• Cross-referencing local field knowledge with mapped building data for validation.

Strengths

• Includes a variety of building types such as residential, hospitals, schools, and places of worship.
• Available in multiple geospatial file formats including GEOPACKAGE, SHP, and JSON.
• Data is sourced from the collaborative OpenStreetMap project and maintained by the Humanitarian OpenStreetMap Team (HOT).

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.
