Building Footprints Across Eritrea from OpenStreetMap

OpenStreetMap exports provide building footprints across Eritrea, including residential, hospital, school, and place-of-worship features. The Humanitarian OpenStreetMap Team (HOT) maintains the export, last updated on 2026-05-15. Completeness varies by region, with urban areas likely being more comprehensively mapped than remote areas.

Use Cases

• Population estimation based on building density and type.
• Damage assessment for disaster response based on building footprint changes.
• Urban planning and infrastructure development based on spatial distribution of buildings.
• Cross-referencing local field knowledge with crowd-sourced mapping data.

Strengths

• Includes multiple building types (residential, hospitals, schools, places of worship).
• Available in multiple geospatial file formats (GEOPACKAGE, SHP, JSON).
• Last updated on 2026-05-15.

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.
