HeiGIT generated this geospatial dataset covering approximately 1,800 km of arterial roads in New Caledonia using AI analysis of PlanetScope satellite imagery from 2020 and 2024. It provides deep-learning predictions for road surface, width, and a Humanitarian Passability Index (HPI) to supplement existing OpenStreetMap (OSM) attributes. The data specifically targets motorway, trunk, primary, and secondary road classes.
Detailed methodology is available in ArXiv paper 2512.04092. The dataset is provided under the hdx-other license which may contain specific usage restrictions.
