In our role as the New Zealand Hydrographic Authority (NZHA), we’re responsible for preparing our country for the rollout of a new Universal Hydrographic Data Model – known as the S-100 standard.
S-100 products will be gradually phased in across the maritime community by 2030. Timings will align with those set by the International Hydrographic Organisation (IHO) to meet the update of the International Maritime Organisation (IMO) SOLAS S-100 ECDIS Performance standard.
By adopting and implementing S-100, shipping and related services will receive up-to-date information in real time, unlocking the potential of combining data to:
- improve navigation safety - in open ocean and port environments
- improve efficiency and optimise load capacity for ships
- reduce carbon emissions
- pave the way for autonomous shipping and e-navigation
- use of data beyond navigation.
LINZ is working to help mariners prepare for this digital future by introducing three S-100 products from 2026. These products are the S-101 (Electronic Navigational Charts), S-102 (Bathymetry) and S-104 (Water Level).
These foundational products will enable New Zealand mariners to enjoy the many benefits provided by a modern, geospatial S-100 data standard. LINZ is currently preparing for the production and distribution of these next-generation charting products.
What is S-100?
The S-100 is a technical framework that improves the interoperability of related datasets, enabling the seamless integration of data and messaging.
By blending together different data formats in real-time, the framework synthesises layers of complex information that are critical for decision-making. Ultimately, it will improve the safe navigation of vessels in open oceans or within ports – onboard both crewed vessels and autonomous ships of the future.
Mariners will be able to send and receive information about the physical environment – for example tides, weather, ice and other hazards. They’ll also be able to share information about berthing and land-side services, maximising the efficiency of ports, ships, and landside transport providers.
