Imagery in this service

• Flag of Norway — shown as a faint background watermark. The flag is a national symbol and its design is in the public domain; the file follows the official geometry and colours published on Wikimedia Commons. It is used as decoration only. It is not part of our logo or of any mark we claim, and its presence does not indicate that this service is operated, endorsed or approved by the Norwegian state.
• Compass rose — our own emblem, and the star and rhumb lines drawn across the page background. The compass rose with radiating rhumb lines is a cartographic convention in use on portolan charts since the 13th century and is not anyone's property; these renderings were made for this service.

Trademarks

BarentsWatch, Kystverket, OpenStreetMap and Kartverket are the marks of their respective owners. They are named here solely to credit the origin of the data shown in this service. Naming them does not imply any partnership with, endorsement by, or approval from those organisations.
