Vietnam Arterial Road Surface and Passability Data (2020-2024)

HeiGIT produced this geospatial dataset covering 68,100 km of arterial roads in Vietnam using PlanetScope satellite imagery from 2020 and 2024. It provides AI-derived classifications for road surface, width, and a Humanitarian Passability Index (HPI) to supplement missing OpenStreetMap attributes.

Use Cases

• Identifying infrastructure upgrades by filtering for 'Road Surface Change' from unpaved to paved between 2020 and 2024
• Planning disaster response logistics using the 'Humanitarian Passability Index' to determine vehicle access levels
• Estimating transport capacity for heavy machinery based on 'Road Width Class' (1-3)

Strengths

• 89.2% surface model accuracy
• Covers 68,100 km of road network
• Includes 2020-2024 temporal change indicators

Limitations

• Geographic scope is limited to Vietnam
• AI-derived attributes may contain errors in regions with high cloud cover or dense vegetation
• Excludes minor and residential road classes
