Cook Islands Road Surface and Passability Metrics (2020-2024)

HeiGIT generated this dataset of AI-derived road surface, width, and passability metrics for arterial roads in the Cook Islands using PlanetScope satellite imagery from 2020 and 2024. It covers approximately 100 km of road segments classified as motorway, trunk, primary, or secondary in OpenStreetMap.

Use Cases

• Assessing logistical constraints for heavy transport using 'Road Width Class' and 'Humanitarian Passability Index (HPI)'
• Identifying infrastructure improvements by tracking 'Road Surface Change' between 2020 and 2024 predictions
• Enhancing transport network models by integrating 'DL Surface Prediction' where 'surface tag' is null

Strengths

• AI surface model achieves 89.2% accuracy compared to 64.7% for OSM tags
• Includes multi-temporal data from 2020 and 2024 for change detection
• Standardized width classes (1-3) based on vehicle capacity and flow

Limitations

• Restricted to arterial roads (motorway, trunk, primary, secondary), omitting local and residential networks
• Small total coverage area of approximately 100 km
• AI predictions may be affected by environmental factors like cloud cover or shadows in satellite imagery
