About S-100

The S-100 Universal Hydrographic Data Model (S-100) is a set of guidelines and definitions for designing and maintaining hydrographic geospatial products and services. It is the new international standard being developed by the International Hydrographic Organization (IHO) to ensure consistency in maritime products and services . S-100 supports the integration of various digital nautical data including:

Please visit the S-100 products specification glossary page for view a full list of the S-100 standards that Canada is contributing to.

S-100 hydrographic products and services take advantage of high-definition data in near real-time where possible resulting in:

The S-100 standards are set to be operational by the January 1, 2026 deadline set by the IHO.

Canada and S-100

The Canadian Hydrographic Service is a leader in contributing to the development of S-100 products and services at the IHO. By adopting the S-100 universal hydrographic data model in the production of hydrographic products and services, mariners in Canadian waters have access to the most up-to-date and detailed information for safe and efficient navigation.

Canada's contributions to its implementation involve:
