Depth data

These are downloadable files with unclassified depth data for general use. Depth information is referenced to nautical chart zero level defined in Norway. Coastal contours, coastal construction and islets/awash rocks are referenced to the medium high tide level. This depth data is the basis for the navigational products and the services of the Norwegian Hydrographic Service. Depths. The depth curves are selected in accordance with the Armed Forces navigation plan, i.e., 50m between depths, and the following curve intervals: 2, 5, 10, 15, 20, 30, 40, 50, 100, 150, 200, 250, and so on.

Purpose

The depth data was compiled in order to support the production of navigational products (nautical charts, electronic nautical charts and pilot sketches). Hydrographic survey data of varying ages and qualities has been compiled to form a seamless terrain model from which the depth data is derived. This work has been in progress since 1997 and is updated continuously as user requirements are reported in.

Depth data can be used for presentation of terrain variation in sea, and for the basis of planning and analysis. The depth data is only in saltwater, not fresh water.

The data is not approved for navigation.

Spatial scope
Specific usage

Depth data can be used for planning, modeling, illustrations, research and analysis in connection with, for example:

- coastal zone planning

- development in ports and coastal zones

- environmental monitoring

- geological surveys

- preliminary mass calculation

- the basis for different types of thematic maps

- pre-design of various petroleum activities

- planning of fisheries and aquaculture

- support for conservation areas

- support for emergency plans

- pre-planning of sea cables / pipeline routes

The depth data is only in saltwater, not fresh water.

The depth data set is also available as a WMS and WFS service.

If you need high-resolution depth data, please use Sjømålingsdata.
