HeiGIT generated this dataset of AI-derived road attributes for approximately 900 km of arterial roads in Guinea-Bissau using PlanetScope satellite imagery from 2020 and 2024. It provides surface type, width classifications, and humanitarian passability scores for segments classified as motorway, trunk, primary, and secondary in OpenStreetMap.
Methodology is detailed in arXiv:2512.04092; data is available in GeoJSON and GeoPackage formats under the hdx-other license.
