The extreme points of Norway include the coordinates that are farther north, south, east or west than any other location in Norway; and the highest and the lowest altitudes in the country. The northernmost point is Rossøya on Svalbard, the southernmost is Pysen in Lindesnes Municipality, the easternmost is Kræmerpynten on Svalbard, and the westernmost is Hoybergodden on Jan Mayen.[1] The highest peak is Galdhøpiggen, standing at 2,469 m (8,100 ft) above mean sea level, while the lowest elevation is sea level at the coast.[2]
The Norwegian Antarctic territories—Bouvet Island, Queen Maud Land and Peter I Island—are not part of the Kingdom of Norway.[3] If included, the Antarctic territories account for the southernmost, easternmost, westernmost and highest extreme points.[4][5]
The latitude and longitude are expressed in degrees, minutes and seconds, in which an "N" value refers to the northern hemisphere, and an "S" value refers to the southern hemisphere. Similarly, a "E" longitude value refers to the eastern hemisphere, and a "W" refers to the western hemisphere. The extreme points of latitude and longitude are published by the Norwegian Mapping Authority, while the elevations are published by the World Fact Book. Both make use of the World Geodetic System (WGS) 84, a geodetic reference system.
