EPSG:5120

ETRS89 / NTM zone 20

Attributes

Unit: metre

Geodetic CRS: ETRS89

Datum: European Terrestrial Reference System 1989 ensemble

Data source: EPSG

Information source: Norwegian Mapping Authority

Revision date: 2020-03-30

Scope: Engineering survey.

Remarks: ETRS89 / 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.

Center coordinates
-1361385.56 548136.07

Projected bounds:
-1406740.61 507651.93
-1316441.71 588830.07

WGS84 bounds:
-1.43 51.7
-0.36 52.24

United Kingdom (UK) - on or related to East West Rail (Phase 2) routes from Oxford to Bicester, Bletchley and Bedford, and from Claydon Junction to Aylesbury and Princes Risborough.
