Marine geospatial data (marine geodata) is essential for marine planning at the local, regional, or national levels, planning for the future of the ocean and coasts, science and more.

Accessible marine geospatial data

  • Hydrographic survey data, traditionally called fair sheets, contain the soundings from the hydrographic survey.
  • Marine primary data consists mainly of seamless depth data and coastline data, in vector format.
  • Terrain models of the seabed: 5x5 meter, 25x25 meter and 50x50 meter regular grids of northern Norway (north of 67 degrees) are available.

Restricted access in coastal areas

Data inside the territorial limit of 12 Nm are subject to military restrictions. This means that data more dense than 50x50 meter between the nodes are defined as classified information in coastal areas.

Products with such limitations are hydrographic survey data and terrain models.

If a customer wants access to such data, the Norwegian Hydrographic Service can apply for permission from the Norwegian Armed Forces, on behalf of the customer.

Order marine geospatial data

Marine spatial data can be ordered via the Norwegian Hydrographic Service by e-mail,

Members of Norway Digital, the national geographical infrastructure, have free access to marine spatial data through the portal (only in Norwegian).
