This service contains generalized depth curves in the Norwegian Sea, as well as detailed shadow reliefs along the coast of Northern Norway. The data is not detailed. The depth curves come from very different sources and have widely varying quality and accuracy. The overview data must only be used as background information. The detailed shadow reliefs are of good quality because they are based on modern surveys.

The main chart series covers the coast of Norway from the border with Sweden to Grense-Jakobselv. The scale is normally 1:50,000. This also includes port chart series, which are nautical charts at more detailed scales which show ports and seaward approaches along the coast of Norway. Planning charts at less detailed scales are also included in this service. The coastal chart series is not included in the service. Updates are imported approx. Once a fortnight as Efs publishes them. Layers can be changed or removed in the future without notification.

WMS service for electronic nautical charts. Includes the official electronic navigation charts (ENC). These electronic nautical charts are produced in accordance with the International Hydrographic Organization's (IHO) standard for the exchange of digital nautical chart information, S57. The WMS service is updated regularly.

Elektroniske sjøkartdata er basert på norske offisielle ENC-er (Electronic Navigational Charts). Disse elektroniske sjøkartene er fremstilt i henhold til the International Hydrographic Organization (IHO) sin standard for utveksling av digital sjøkartinformasjon, S57. Dataene er standardisert med hensyn på innhold, struktur og format. Elektroniske sjøkartdata kan kombineres med mange typer data. Kartverket oppdaterer elektroniske sjøkartdata kontinuerlig.

Havnekartserien består av 45 sjøkart i målestokk fra 1:5 000 til 1:25 000. Den dekker havner og innseilinger langs norskekysten. En del havnekart har spesialer i større målestokker over sentrale deler av havner eller trange farvann. Havnekart gir brukeren et detaljert bilde av dybdeforhold og kaianlegg i havnene. Tjenesten oppdateres to ganger pr måned med nye og endrede sjøkart.

The dataset shows terrain variations on the seabed. These terrain models have been produced by using high quality hydrographic survey data. \\nThe 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 50m x 50m. 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.

Hovedkartserien Svalbard, Jan Mayen og Bouvetøya består av 21 sjøkart i målestokk: 1:15 000 til 1:100 000. Den dekker kystnære polare strøk. Store deler av Svalbard gjenstår før området er dekket av kart i målestokk 1:100 000, selv om det er den mest vanlige målestokken. Oppdateringer legges inn ca. hver 14. dag i takt med Efs utgivelse.

Kystkartserien består av 12 kart i målestokk fra 1:200 000 til 1:350 000. Kartserien dekker norskekysten fra svenskegrensen til Grense Jacobselv. Kartene i kystkartserien brukes til navigering i kyststrøk som ikke er dekket av hovedkartserien, i utenskjærs seilas langs kysten, samt på fiskebankene. Kartene utgis i Mercator projeksjon
