Building Footprints Across Ireland from OpenStreetMap

Ireland's building footprints exported from OpenStreetMap, including features tagged as buildings such as residential homes, hospitals, schools, and places of worship. The dataset is provided by the Humanitarian OpenStreetMap Team (HOT) and was last updated on 2026-05-14. Completeness varies by region, with urban areas typically well-mapped and remote areas potentially incomplete.

Use Cases

• Population estimation based on building density and type.
• Damage assessment for disaster response using building footprint locations.
• Urban planning analysis of building distribution and land use.
• Infrastructure mapping for services like schools and hospitals.

Strengths

• Includes every OpenStreetMap feature tagged as a building (`building=*`).
• Covers a wide range of building types, from residential to institutional.
• Available in multiple geospatial file formats (GEOPACKAGE, SHP, 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.
