HeiGIT produced this dataset covering 68,800 km of arterial roads in the Republic of Korea using PlanetScope satellite imagery from 2020 and 2024. It features AI-derived attributes for road surface, width, and a Humanitarian Passability Index (HPI) to fill significant data gaps in OpenStreetMap.
The dataset is provided in GeoJSON and GeoPackage formats; users should verify the hdx-other license terms before commercial use.
