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.

This image depicts information about maritime navigation and data standards. It is divided into several sections, each illustrating different aspects of marine navigation and safety. It displays a range of S-100 based data models designated for specific maritime information.The different data models are:
S101 - Electronic Navigational Charts (ENC)
S102 - Bathymetric Surface
S104 - Water Level Information
S111 - Surface Currents
S122 - Marine Protected Areas
S123 - Radio Services
S124 - Navigational Warnings
S128 - Catalogues of Nautical Products
S129 - Under Keel Clearance Management (UKCM)
S131 - Marine Harbour Infrastructure
S201 - Aids to Navigation Information
S411 - Ice Information
S412 - Weather Overlay
S413 - Weather and Waves Conditions
S414 - Weather and Waves Observations
S421 - Route Exchange Format
