Baltic Sea E-Nav

A new data model, the S-100 Universal Hydrographic Data Model, has been introduced by the International Hydrographic Organization (IHO) to support the production of electronic nautical charts and related data products. Building on this model, product specifications have been developed that redefine the way essential navigation information is designed, including nautical charts, bathymetry, water levels, and surface current conditions. This innovative method of producing, visualizing, and combining multiple layers of information will lead to digital nautical charts featuring dynamic depth contours and enhanced tools for safer and more efficient route planning and decision-making.

The Baltic Sea E-Nav project aims to develop and produce some of the first S-100-based products for the Baltic Sea region. By fostering seamless navigation and coordinating development efforts among Baltic Sea nations, the project adopts a transnational approach, engaging nine countries and 14 organizations. The project is EU-funded through Interreg Baltic Sea Region and is led by the Swedish Maritime Administration.

Project Outputs

The Baltic Sea E-Nav Base Package includes:

• S-101 next-generation electronic navigational charts with full coverage of the major shipping routes in the Baltic Sea.
• S-102 seafloor information products will cover most relevant shipping routes, fairways and harbor approaches, where hydrographic survey data of sufficient quality is available.
• S-104/S-111 water levels and surface currents. The Finnish Meteorological Institute will develop information services for most areas within Finnish waters in the Baltic Sea. For Swedish test areas, SMHI (Swedish Meteorological and Hydrological Institute) will begin producing S-104 and S-111.Guidelines adopted regionally under Baltic Sea Hydrographic Comission (BSHC).

·         These guidelines will regulate how the products and services shall be harmonised across borders between different nation‘s respective resonsibility.

Duration

The products will be available for commercial use after the project's completion in October 2026, the year when compatible S-100 navigation systems will be approved for use.
