The Norwegian Mapping Authority Hydrographic Service is responsible for preparing and updating nautical charts, and covers all marine and coastal waters in Norway and around Svalbard, as well as Norwegian areas in the Antarctic.
All tasks undertaken by the Norwegian Mapping Authority involve geographical or ratified information, whether in regard to data on which a map is based, the name of a town, property boundaries or property rights issues.
The Norwegian Hydrographic Service was established in 1932 and has operated as a division of the Norwegian Mapping Authority since 1986. The division has 120 employees and is based in Stavanger.
Official nautical charts
The Norwegian Hydrographic Service is the only authorised producer of official nautical charts and electronic navigational charts (ENC) in Norway, and vessels over a certain size are obliged to use these charts. As well as cartographical work, the Hydrographic Service is also responsible for information about tidal waters and currents.
The Norwegian Hydrographic Service is required to facilitate safe and effective navigation in Norwegian coastal and marine areas. The Hydrographic Service undertakes this task by gathering, administering, processing and publishing official maritime information to a range of user groups.
Charting the ecosystem
While safe coastal navigation takes top priority, the Hydrographic Service’s deep water database is also useful for other purposes, including coastal zone planning and administration of fisheries.
As a supplier of bathymetric data, the Norwegian Mapping Authority helps to improve knowledge of the structure, mode of operation and status of the marine ecosystem. This knowledge provides a framework for establishing sustainable management of coastal and marine areas in Norway.
Primar is an international collaboration dedicated to providing a consistent and reliable electronic navigational chart (ENC) service, and is operated on a non-profit basis by the Norwegian Hydrographic Service.
