EPSG:5125

ETRS89 / NTM zone 25

Selected transformation

Method: NTv2

Grid Files: s45b_2022.gsb

Remarks: In conjunction with the S45B-reconstruction map projection (code 10253) applied to S45B-IRF (code 10252), enables transformation of coordinates between the historic CRS S45 and ETRS89. File is also available in GeoTIFF format (s45b_2022.tif).

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 25°E and 26°E.

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

Center coordinates
-573013.3 735000.59

Projected bounds:
-597760.56 707492.14
-548483.55 762589.02

WGS84 bounds:
14.59 54.94
15.25 55.38
