A 2026 dataset from the Heidelberg Institute for Geoinformation Technology (HeiGIT) provides AI-derived road surface classifications for the Seychelles. It distinguishes paved and unpaved roads using a hybrid deep learning approach on OpenStreetMap data, augmented with Mapillary imagery and urban layers. The data indicates approximately 0.0014 million km of roads are mapped, with AI estimates for paved (0.0002 million km) and unpaved (0.0001 million km) segments.
