Comoros Road Surface Classification from OpenStreetMap and AI Predictions

HeiGIT (Heidelberg Institute for Geoinformation Technology) provides a dataset detailing road surfaces in Comoros, derived from OpenStreetMap and augmented with deep learning predictions from Mapillary imagery. It distinguishes paved and unpaved roads, covering approximately 0.0025 million kilometers of mapped roads, with AI-derived estimates for 11.6003% paved and 7.7376% unpaved. The dataset was last updated on March 2, 2026.

Use Cases

• Transportation planning based on road surface type classification (paved/unpaved).
• Infrastructure analysis based on OSM attributes like highway type, surface, and width.
• Climate emissions assessment based on road surface data for vehicle emission modeling.
• GIS applications for routing and logistics based on urban/rural classification attributes.

Strengths

• Includes AI-derived surface predictions for roads where OSM data is missing, using a hybrid deep learning approach detailed in a referenced paper.
• Combines data from multiple sources: OpenStreetMap, Mapillary imagery, GHSU Global Human Settlement Urban Layer 2019, and AFRICAPOLIS 2020.
• Provides specific statistics on road coverage, including that approximately 0.002 million km (80.6621%) of surface information is missing in OSM.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
