Isle of Man Road Surface and Passability Data (2020-2024)

Offering AI-derived road surface, width, and passability metrics for approximately 500 km of arterial roads in the Isle of Man, produced by HeiGIT. It utilizes PlanetScope satellite imagery from 2020 and 2024 to supplement OpenStreetMap (OSM) data, focusing on motorway, trunk, primary, and secondary road classes.

Use Cases

• Evaluating logistical accessibility for heavy vehicles using the Road Width Class (1-3)
• Monitoring infrastructure development trends via the Road Surface Change indicator
• Planning humanitarian or emergency routing based on the Humanitarian Passability Index (HPI)

Strengths

• 89.2% surface prediction accuracy compared to 64.7% for standard OSM tags
• Multi-temporal analysis identifying road surface changes over a four-year span
• Standardized width classification based on heavy vehicle capacity

Limitations

• Geographic scope is limited to the Isle of Man
• Excludes non-arterial road classes which may be critical for last-mile logistics
• AI predictions may be affected by environmental factors like cloud cover or dense canopy
