Monaco is hosting the 4th General Assembly of the International Hydrographic Organization (IHO), bringing together the global hydrographic community to address the future of ocean mapping and maritime safety…

Held every three years, the event runs at the Auditorium Rainier III, this year from from April 20 to 23, gathering representatives from governments, maritime authorities and industry leaders.

His Serene Highness Prince Albert II opened the assembly, underlining the importance of better understanding, preserving and protecting the world’s oceans. Over four days, delegates are discussing key developments in hydrography, including advances in seabed mapping, data standards and ocean exploration technologies.

A central focus of this year’s discussions is the transition towards new digital standards, notably the S-100 framework, which enables more detailed and dynamic maritime data. Innovations such as the growing use of drones and autonomous systems are also reshaping how hydrographic surveys are conducted, complementing traditional vessels.

During the opening ceremony, the Prince Albert I Medal for Hydrography was awarded to individuals recognised for exceptional contributions to the field. The assembly also marked the inclusion of new member states, bringing the organisation’s total to 104 countries.

By hosting this major international gathering, Monaco reinforces its position at the forefront of ocean governance and scientific cooperation, at a time when accurate maritime data is more crucial than ever.
