Offering AI-derived road attributes for approximately 24,500 km of arterial roads in Cameroon, generated by HeiGIT using PlanetScope satellite imagery from 2020 and 2024. It includes surface type, road width, and a Humanitarian Passability Index (HPI) for segments classified in OpenStreetMap as motorway, trunk, primary, and secondary. The analysis fills critical data gaps, providing surface information for 489% more road length than is currently tagged in OSM.
Data is provided in GeoJSON and GeoPackage formats; users should note that HPI Score 1 represents the highest passability while Score 6 represents the lowest.
