EPSG:5120

ETRS89-NOR [EUREF89] / NTM zone 20

Attributes

Unit: metre

Geodetic CRS: ETRS89-NOR [EUREF89]

Datum: ETRS89-NOR [EUREF89]

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: Norwegian Mapping Authority, https://www.kartverket.no/

Revision date: 2025-09-12

Scope: Engineering survey.

Remarks: EUREF89 / UTM is the projected CRS for Norway recommended by the Norwegian Mapping Authority. This CRS using NTM is an alternative when UTM scale is too far from unity, in particular for construction projects.

Area of use: Norway - onshore - between 20°E and 21°E.

Coordinate system: Cartesian 2D CS. Axes: northing, easting (N,E). Orientations: north, east. UoM: m.
