Belize Arterial Road Surface, Width, and Passability (2020-2024)

AI-derived road surface, width, and passability metrics for approximately 1,200 km of arterial roads in Belize. Produced by HeiGIT using PlanetScope satellite imagery from 2020 and 2024, it covers motorway, trunk, primary, and secondary road classifications.

Use Cases

• Evaluating emergency vehicle access using the Humanitarian Passability Index (HPI) score
• Identifying infrastructure improvements by filtering for 'unpaved to paved' transitions in the Road Surface Change column
• Determining heavy transport feasibility based on Road Width Class 3 (>5.5 m) segments

Strengths

• 89.2% accuracy for AI-derived surface model predictions
• Multi-temporal coverage (2020 and 2024) allows for infrastructure change detection
• Standardized Humanitarian Passability Index (HPI) for logistical accessibility

Limitations

• Geographic scope is limited to the arterial road network
• AI-derived predictions may contain classification errors inherent to satellite imagery analysis
