Unveiling the Progress of IHO S-100: The Innovative Geospatial Standard for Hydrographic Data of the International Hydrographic Organization
The International Hydrographic Organization (IHO) is leading a significant shift in the maritime industry with the introduction of the IHO S-100 standard. This modern, evolving global framework is set to revolutionise the integration of diverse maritime datasets, going beyond traditional navigation.
IHO's primary function is to support the safety of navigation and contribute to the protection of the marine environment. In line with this mission, IHO is a Class A Liaison Organization to ISO/TC211, a group responsible for geographic standards development.
The Evolution of S-100 and S-57
The IHO S-100 standard builds on and extends the capabilities of the older IHO S-57 standard, which has been the format for Electronic Navigational Charts (ENCs) since 1992. While S-57 remains the operational standard for ENCs today, the shipping industry and hydrographic bodies are transitioning toward S-100 to enable richer, flexible, and interoperable marine data applications.
S-100 is a broader framework for multiple marine data types and integration beyond just ENCs. It supports a broad range of nautical product specifications like electronic navigation charts (S101), bathymetric surfaces (S102), water level info (S104), weather overlays, marine protected areas, and more, facilitating a richer, multi-layered maritime information environment.
Current Status and Key Differences
S-100 is actively being rolled out and tested, with pilot trials such as those on the St. Lawrence River by the Canadian Hydrographic Service. It is gaining traction as the next-generation framework that will become mandatory for maritime vessels by 2029.
The UK Hydrographic Office has developed resources and surveys to promote industry awareness and prepare stakeholders for the transition. Key differences between S-100 and S-57 include a broader purpose, scope of application, technical foundation, data complexity and richness, and standards alignment.
The Future of Maritime Data
S-100 represents a "revolutionary step forward" as described by IHO, aiming to enhance the integration of marine information systems in a standardized way, extend the utility of charting data beyond navigation into broader maritime domain awareness, and align hydrographic data more closely with international geospatial standards.
In summary, while S-57 remains the operational standard for ENCs today, the shipping industry and hydrographic bodies are transitioning toward S-100 to enable richer, flexible, and interoperable marine data applications with mandatory adoption expected by 2029.
