Sierra Leone Road Network from OpenStreetMap for Routing and Analysis

OpenStreetMap's road network for Sierra Leone includes features tagged with `highway`, such as motorways, residential streets, and footways. The Humanitarian OpenStreetMap Team (HOT) maintains this export, which was last updated on 2026-05-14. Completeness of the data varies, with urban areas likely being better mapped than remote regions.

Use Cases

• Plan evacuation routes based on the network of motorways and residential streets.
• Analyze accessibility to services based on the inclusion of footways and trails.
• Perform routing analysis for logistics using the categorized road network.

Strengths

• Includes a diverse range of road types, from motorways to trails, as specified by the `highway` tag.
• Data is provided in multiple geospatial formats (GEOPACKAGE, SHP, JSON) for flexibility.
• Last updated on 2026-05-14, indicating recent maintenance.

Limitations

• Completeness varies by region; remote areas may be incomplete according to the description.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
