This dataset, which contains terrain models of the seabed, shows the variations in the terrain on the seabed. These terrain models have been produced by using high quality hydrographic survey data.

This dataset is suitable for planning at the detail level. This data is frequently used for planning the routes for submarine cables, pipelines, and subsea tunnels, etc.; planning of the development of harbour areas or the coastal zone; different types of thematic maps; petroleum activities; modelling of ocean currents, sea level changes, and marine pollution, etc.; fishing and aquaculture; mapping of seabed conditions, marine vegetation, and conservation areas, etc.; and emergency response planning, and in search and rescue operations.

There are no restrictions on use. Members of Norway Digital, the national geographical infrastructure, can download all open data from the Norwegian Hydrographic Service at this Internet address: http://data.kartverket.no/download/content/geodataprodukter?korttype=3631&aktualitet=All&datastruktur=All&dataskema=All

The 25x25 meter grids are defined as classified information inside the Norwegian territorial limit of 12 nautical miles. 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. The application will normally be approved on the condition that the data is returned/destroyed within five years.

This dataset is organized as areas of 30X30 minutes, i.e. ENC D-cells, in ASCII files in EUREF89 datum and (most often) UTM zone 33 coordinates (source: https://www.kartverket.no/en/data/kartdataer/Marine-Geospatial-Data/Terrain-Models-of-the-Seabed/). The exceptions to the UTM33 deliveries are in the Hordaland county and in the Trondheim fjord, which are delivered in UTM zone 32. It is possible to obtain the datasets in geographical coordinates as well, but at the present time only by direct contact to sjodata@kartverket.no.
