EPSG:5127

ETRS89 / NTM zone 27

Selected transformation

Method: NTv2

Grid Files: rgf93_ntf.gsb

Remarks: These parameter values are taken from RGF93 to NTF (2) (code 15958) as RGF93 may be considered equivalent to ETRS89 within the accuracy of the transformation.

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 27°E and 28°E.

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

Center coordinates
-1833485.66 5805.4

Projected bounds:
-2622643.4 -699208.87
-1146044.65 752180.47

WGS84 bounds:
-4.87 41.31
9.63 51.14

France - onshore - mainland and Corsica.
