The WMS service shows the depth conditions in Norwegian sea areas as shadow relief with resolutions of 5 m, 25 m, 50 m. The data on the map is scale-dependent and more details are shown when one zooms into the map. If you zoom into the map, this will automatically take you to 50-meter resolution, then on to 25 meters and – if the data is detailed enough – down to a 5-meter resolution between depth points. There are 5 meter and 25 meter grids, but only outside the territory boundary (12 nautical miles) as data within the territorial boundary is classified by the Norwegian Armed Forces. The very few areas, which have been released by the Norwegian Armed Forces, are exempted from this. The shadow relief is derived mainly from regular grids (terrain models), which are based solely on modern multibeam surveys. The dataset has best coverage in the areas in Northern Norway where the Norwegian Mapping Authority Hydrographic Service and partners have carried out hydrographic surveys over the past few years. The dataset also has some coverage in Central Norway and will be extended as new hydrographic surveys are carried out and terrain models are produced for the seabed.

The dataset shows terrain variations on the seabed. These terrain models have been produced by using high quality hydrographic survey data. The data in this dataset, which are close to the shoreline, includes some coverage in Central Norway (large areas in Hordaland, and otherwise, certain areas in the counties of Sogn and Fjordane, Møre and Romsdal, and Trøndelag). But the dataset has the best coverage in the areas in Northern Norway, with almost continuous coverage north of 67 degrees. In ocean areas, the coverage is largely dependent on the surveys organized by the MAREANO program (for more information: www.mareano.no/en). MAREANO has surveyed the ocean areas off the coast of all of the northern counties: Møre and Romsdal, Trøndelag, Nordland, Troms, and Finnmark; plus the eastern part of the Barents Sea, and, otherwise, certain areas around Svalbard. The coverage area is extended continuously and the data is updated whenever new hydrographic surveys are finished being processed. The resolutions of the terrain models are 5m x 5m. Partners in Norge Digital have the possibility of downloading data from the Norge Digital downloading service. Other users must request the data by sending an application or an order to: sjodata@kartverket.no.

In areas farther from the shore, the coverage is largely dependent on the surveys organized by the MAREANO program (for more information: www.mareano.no/en). MAREANO has surveyed the ocean areas along the coast of all of these northern counties: Møre and Romsdal, Trøndelag, Nordland, Troms, and Finnmark; plus the eastern part of the Barents Sea, and, in addition, certain areas around Svalbard. The coverage area is being extended continuously and the data is updated whenever new hydrographic surveys are finished being processed. The resolutions of the terrain models are 25m x 25m.
