Road Network of Nigeria from OpenStreetMap, Including Highways and Trails

OpenStreetMap data provides a road network across Nigeria tagged with the `highway` key, including motorways, residential streets, service roads, footways, and trails. The dataset is part of the exports grid on HDX by the Humanitarian OpenStreetMap Team and was last updated on 2026-06-26. Coverage reflects where volunteer mappers have been active, with urban areas usually well represented and remote areas potentially sparse.

Use Cases

• Route planning and navigation based on the detailed highway network classification.
• Accessibility analysis for services and infrastructure based on road connectivity.
• Evacuation and disaster response planning based on the mapped road network.
• Urban and regional transportation studies based on the types and distribution of roads.

Strengths

• Data is sourced from OpenStreetMap, a free, collaborative world map with a large contributor base.
• Includes multiple geospatial file formats (GEOPACKAGE, SHP, JSON, HTML) for flexibility.
• Explicitly tagged with the OpenStreetMap `highway` key, providing a structured classification for road types.

Limitations

• Coverage is uneven, with urban areas likely well-mapped and remote areas potentially sparse, reflecting volunteer mapper activity.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analyses.
