The depth data is administered in the Hydrographic Service's maritime primary database. The depth data was compiled in order to support a digital production trail for navigation products (nautical charts, electronic nautical charts and pilot sketches). Hydrographic survey data of varying age and quality 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 regularly as user requirements are reported.The depth data is taken mainly from hydrographic survey data measured using multibeam echo sounders, lasers and single beam echo sounders. In some places, smaller areas with little shipping may originate from digitised older nautical charts.
Areas that have not been surveyed are also described in this dataset.

WFS for the dataset Depth data. This is 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.
Areas that have not been surveyed are also described in this dataset.
