HeiGIT generated this geospatial dataset covering 132,100 km of arterial roads in Italy using AI analysis of PlanetScope satellite imagery from 2020 and 2024. It provides deep-learning predictions for road surface, width, and passability for segments classified as motorway, trunk, primary, and secondary in OpenStreetMap.
Data is provided in GEOJSON and GEOPACKAGE formats; users should refer to the linked ArXiv paper (2512.04092) for detailed methodology on the HPI scoring and width classification.
