Nigeria Building Footprints and Attributes from OpenStreetMap

OpenStreetMap exports from the Humanitarian OpenStreetMap Team contain all features in Nigeria where the 'building' tag is not null. The dataset includes potential attributes such as name, building type, levels, materials, and address components. It was last updated on 2026 03 03 and is available in multiple geospatial formats including GeoPackage, GeoJSON, and Shapefile.

Use Cases

• Urban density analysis based on building footprint locations.
• Infrastructure type classification based on the 'building' and 'office' attribute tags.
• Address validation and geocoding using the 'addr:full', 'addr:street', and 'addr:city' fields.
• Building material analysis for risk assessment using the 'building:materials' tag.

Strengths

• Data is provided in five common geospatial formats (GARMIN IMG, GEOPACKAGE, GEOJSON, SHP, KML).
• Attributes are linked to the OpenStreetMap wiki for detailed tag semantics.
• Dataset is sourced from the Humanitarian OpenStreetMap Team, a recognized authority in open mapping.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred from the linked OpenStreetMap wiki.
• Data may reflect geographic or contributor bias inherent to OpenStreetMap's crowdsourced nature.
