A 2026 dataset from HeiGIT provides AI-derived road surface classifications for Saint Helena, distinguishing paved and unpaved roads. It is based on OpenStreetMap data augmented with deep learning predictions from Mapillary imagery and PlanetScope satellite data. The dataset includes approximately 0.0005 million kilometers of mapped roads, with surface information missing for about 75.728% of that length in the original OSM data.
