Method: NTv2
Grid Files: TN15-ETRS89-to-ECML14_NB-IRF.gsb
Remarks: In conjunction with the ECML14_NB-TM map projection (code 9760) applied to ECML14_NB-IRF (code 9758), emulates the ECML14_NB Snake projection. Applied to ETRS89 (as realized through the OSNet v2009 CORS) defines ECML14_NB-IRF hence is errorless.

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 28°E and 29°E.
Coordinate system: Cartesian 2D CS. Axes: northing, easting (N,E). Orientations: north, east. UoM: m.
