Hydrographic Service

The Hydrographic Service of the Royal Netherlands Navy informs mariners about shipping routes, the seabed and underwater hazards such as shipwrecks. To this end, the Hydrographic Service compiles nautical charts, carefully details the maritime borders of the Netherlands and carries out depth measurements. The Hydrographic Service thus contributes to the protection of Dutch interests at sea and to safe shipping routes. Go directly to Hydrography and Notices to Mariners.

In 2024 the Hydrographic Service celebrates its 150th anniversary.
