PortWatch Chokepoints: 28 Strategic Maritime Passages for Global Trade

28 major global maritime chokepoints, such as straits and canals, critical for global shipments. The dataset, created by PortWatch, tracks these narrow passages where large traffic volumes are vulnerable to disruptions from conflict, disasters, or accidents. It was last updated on March 24, 2026.

Use Cases

• Modeling supply chain disruption risk based on chokepoint vulnerability.
• Analyzing global trade flow patterns through strategic maritime passages.
• Visualizing geographic distribution of critical shipping chokepoints for logistics planning.
• Assessing the impact of geopolitical or natural events on specific trade routes.

Strengths

• Focuses on 28 clearly defined, globally significant maritime chokepoints.
• Includes geospatial data (GeoJSON format) for mapping and location-based analysis.
• Data is actively tracked and analyzed by the PortWatch platform.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
