The full name of S-127 is Marine Traffic Management Product Specification, also known as S-127 Marine Traffic Management. It aims to provide supplementary information for Electronic Chart Display and Information Systems (ECDIS) to improve the management efficiency and safety of marine traffic.

• Data Content: Mainly describes information related to marine traffic management, such as fairway information, vessel traffic services, pilotage, route measures, and ship reporting systems.
• Relationship with S-101: Compared to S-101 data, which focuses on providing basic fairway data with a lower update frequency, S-127 emphasizes dynamic information directly related to marine traffic management. It includes more detailed fairway information, covering service areas, service content, contact details, and related metadata such as quality, production agency, data source, and release date. Given that S-127 data has lower complexity and volume, and is easier to update, it can be prioritized for use.
