N2000 fairway and nautical chart reform - Improved safety and efficiency

N2000 fairway and nautical chart reform

A new selection of nautical chart products and fairway depth information that are tied to the N2000 vertical coordinate reference system will be introduced gradually from 2021 onwards. The reform process is set to begin in the Bay of Bothnia region and, according to current estimates, will reach full sea area coverage by 2026. The current, mean water level-based reference level for depth information for the sea area will be replaced with a reference level that is tied to the N2000 vertical coordinate reference system. The introduction of the N2000 vertical coordinate reference system, which is tied to the Earth's crust, will increase the compatibility of both national and international depth information.

What will the reform mean in practice?

Finnish nautical charts and fairways will adopt a single unified reference level for depth information which is tied to the N2000 vertical coordinate reference system. This reform will help simplify the process used to observe any changes in depth information – primarily as a consequence of land uplift – in practical maritime navigation activities.

Why is the reform being implemented?

Safe navigation, the efficient use of Finnish fairways, and future means of navigation – these all require more up-to-date and harmonised depth information that can be used in nautical chart products and by those navigating our waterways.

How will the reform be implemented?

Under the current plan, all nautical charts and fairway information will be renewed between 2021 and 2026. Those responsible for the maintenance of waterways will be contacted in connection with the changes made to the information concerning their waterways.
