Antarctica Road Surface Classification from OpenStreetMap and Satellite Imagery

A geospatial dataset providing road surface classifications for Antarctica, distinguishing paved and unpaved roads. It is derived from OpenStreetMap data and augmented with deep learning predictions based on Mapillary imagery and PlanetScope satellite data. The dataset was last updated on March 3, 2026, by the Heidelberg Institute for Geoinformation Technology (HeiGIT).

Use Cases

• Transportation planning based on road surface type and urban classification attributes.
• Infrastructure analysis using predicted surface classes and OSM-derived attributes like highway type and width.
• Climate emissions assessment leveraging the distinction between paved and unpaved road lengths.
• GIS applications utilizing the geospatial geometry and combined surface classifications.

Strengths

• Includes AI-derived surface predictions (paved/unpaved) from a hybrid deep learning approach detailed in a published paper.
• Combines multiple data sources: OpenStreetMap, Mapillary imagery, PlanetScope satellite imagery, and urban settlement layers.
• Provides multiple classification fields, including OSM-derived, model-predicted, and combined classifications with different priority rules.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description indicates 0.0 million km of roads are mapped, suggesting the dataset may be illustrative of a methodology rather than containing extensive mapped features for Antarctica.
