Tanzania Road Network with Swahili Names and Surface Attributes

Tanzania road network data exported from OpenStreetMap by the Humanitarian OpenStreetMap Team (HOT) in March 2026. The dataset captures all geospatial features tagged with the 'highway' key, providing geometry and physical attributes for transportation infrastructure across the country.

Use Cases

• Assessing road navigability for logistics using 'surface' and 'smoothness' values
• Modeling urban traffic flow based on 'lanes' and 'oneway' attributes
• Mapping infrastructure elevation and crossings using 'bridge' and 'layer' tags

Strengths

• Available in five geospatial formats including SHP, KML, and GeoPackage
• Includes localized Swahili names via the 'name:sw' attribute
• Contains physical infrastructure details such as 'surface' and 'smoothness' tags

Limitations

• Crowdsourced data may have inconsistent attribute density between different regions
• Total record count and file size are not specified in the source metadata
