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 9°E and 10°E.
Coordinate system: Cartesian 2D CS. Axes: northing, easting (N,E). Orientations: north, east. UoM: m.
