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.

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.
