Uganda Road Surface and Passability: 15,400 km of Arterial Roads

This dataset maps 15,400 km of arterial roads in Uganda, providing AI-derived surface types, widths, and passability scores generated by HeiGIT from 2020 and 2024 PlanetScope satellite imagery. It covers motorway, trunk, primary, and secondary road classes, filling surface data gaps for the 34% of segments that lack tags in OpenStreetMap.

Use Cases

• Logistics planning using the Humanitarian Passability Index (HPI) to identify segments with high blockage risk
• Infrastructure development monitoring by analyzing Road Surface Change from 2020 to 2024
• Transport capacity modeling based on Road Width Class to determine heavy truck accessibility

Strengths

• 89.2% surface prediction accuracy
• Covers 15,400 km of arterial road infrastructure
• Includes temporal change detection between 2020 and 2024
• Standardized Humanitarian Passability Index (HPI) for logistics

Limitations

• Excludes minor and residential road networks
• AI-derived predictions may contain errors compared to ground-level surveys
• Relies on OpenStreetMap geometries which may have varying spatial precision
