Description
OpenStreetMap exports provide the road network across Samoa, including motorways, residential streets, service roads, footways, and trails. The Humanitarian OpenStreetMap Team (HOT) compiled this data, which was last updated on 2026-05-15. Completeness varies by region, with urban areas likely being better mapped than remote locations.
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 transportation planning using the comprehensive highway network.
Assess infrastructure coverage by comparing mapped urban roads to potentially incomplete remote area data.
Strengths
Includes all OpenStreetMap features tagged with 'highway', covering a wide range of road types.
Data is provided in multiple geospatial formats (GEOPACKAGE, SHP, JSON) for flexibility.
Last updated on 2026-05-15, suggesting recent maintenance.
