S-100: Harmonised data exchange

Harmonised data models are critical for the success of digital maritime services. They are crucial for interoperability between different information systems. They also extend existing systems and support the development of new services. Trends such as Maritime Autonomous Surface Ships (MASS) highlight this need.

S-100 standard

The IHO Universal Hydrographic Data Model S-100 is an ISO 19100-based geospatial standard. It supports various types of data sources. 

Data models use S-100 as the framework for representing maritime data. Examples include:

• ENCs (S-101)
• navigational warnings (S-124)
• traffic management information (S-127)
• UKCM data (S-129). 

Australian government agencies are also introducing new data models for their services. The Australian Hydrographic Office is working on providing S-101 ENCs and AMSA is trialling S-124 services. We expect other organisations will follow. New data models will support the next generation of data services. These data services will enhance safety and efficiency in the maritime industry.
