UK Traffic Separation Schemes and Deep Water Routes, Approved Coordinates

United Kingdom Hydrographic Office publishes polygons depicting Traffic Separation Schemes and Deep Water Routes around the UK and in the southern North Sea. The coordinates are approved by the UK Maritime and Coastguard Agency and most are also approved by the International Maritime Organisation. This data was last updated on 2026-07-08.

Use Cases

• Visualizing maritime traffic lanes on navigational charts based on the published polygon data.
• Analyzing shipping route compliance based on the approved Traffic Separation Scheme boundaries.
• Integrating official deep water routes into maritime Geographic Information Systems (GIS).
• Supporting marine safety and collision avoidance planning based on the formally adopted schemes.

Strengths

• Coordinates are formally approved by the UK's national competent authority, the Maritime and Coastguard Agency.
• All but one of the schemes have been approved by the International Maritime Organisation.
• Data is used to depict schemes on official UK Hydrographic Office navigational charts.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified despite the 2026-07-08 update timestamp.
