Our scientific and technical director, Sébastien Mancini, was in Wellington for Hydrospatial 2026 in March 2026 — the Australasian region’s flagship hydrographic and marine geospatial conference.
With the theme Shaping the Future of Marine Discovery, the event brought together national hydrographic offices, technology providers and researchers to talk seriously about where the sector is heading, and how fast it needs to get there. It was a conference grounded less in aspiration and more in implementation — a sign of how far the conversation has shifted in recent years.
Seb presented on S-100 and its role in moving beyond charts towards a connected operational ecosystem. One that supports voyage planning, port calls, dynamic routing and safer decision‑making through integrated data layers.
A recurring theme throughout the conference was that S‑100 is no longer theoretical, it is arriving. Progress is uneven, the complexity is real, and the pathways are not always clear — but the momentum is unmistakable. Across sessions and side conversations, the focus was less on whether S‑100 will be adopted, and more on how it will be implemented responsibly, consistently and at scale.
That shift is important as standards only become valuable when they start to shape day-to‑day operations.
A standout keynote came from Adam Greenland, New Zealand’s national hydrographer at Land Information New Zealand, who framed S‑100 as an enabling platform for integrated marine operations rather than a simple upgrade to navigational products. His talk prompted wide ranging discussion about what that really means in practice.
Questions surfaced repeatedly around data validation, update frequency, governance, and responsibility. Who publishes which products? How often are they refreshed? How are conflicts between datasets resolved? And how do products such as S‑104 and S‑111 move from pilots and trials into trusted operational use?
These are not abstract concerns — they sit at the heart of whether S‑100 delivers tangible benefits to mariners, ports and regulators, or becomes another technically elegant standard that struggles to gain traction.
One point raised repeatedly across sessions and informal discussions was that ports stand to be among the greatest beneficiaries of S‑100. Improved situational awareness, better coordination, safer transits and more efficient operations all sit squarely within the promise of the framework.
Yet port representation at the conference was limited.
By contrast, hydrographic surveyors were out in force. Many have long‑standing, productive working relationships with ports and understand their operational realities well. Surveyors openly acknowledged both the importance of port engagement and the difficulty of getting port stakeholders into the room more often.
This disconnect is not a criticism of ports. They are busy, operationally focused environments with competing priorities. But it does underline a challenge the sector needs to address. If ports are to be major beneficiaries of S‑100, they also need to be active participants in shaping how it is implemented.
What was encouraging, Seb said, was the appetite to move faster. Across hydrographic offices, surveyors and technology providers, there was broad recognition that collaboration is not optional. S‑100 spans hydrography, oceanography, meteorology and navigation, and cuts across institutional and jurisdictional boundaries.
Progress will depend on clearer pathways for publishing and consuming data products, better alignment between producers and users, and continued testing in real operational environments. It will also depend on conversations that are sometimes uncomfortable — about responsibility, readiness and resourcing — but are essential if the framework is to mature.
Events like Hydrospatial play a crucial role in this transition — they move the discussion out of standards documents and into practical reality. They create space for honest technical debate, shared learning and the relationships needed to turn ambition into delivery.
They also remind us that the future of marine discovery will not be shaped by standards alone, but by the people and organisations willing to engage, collaborate and make those standards work.
Thanks to the Australasian Hydrographic Society for a thoughtful, well run event, and to everyone who shared insights, questions and ideas along the way.
