EBBWV14 Grid

Attributes

Unit: metre

Geodetic CRS: EBBWV14-IRF

Datum: EBBWV14 Intermediate Reference Frame

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: Network Rail.

Revision date: 2022-02-10

Scope: Engineering survey and topographic mapping for railway applications.

Remarks: Defined through transformation ETRS89 to EBBWV14-IRF (1) (code 9941) and map projection EBBWV14-TM (code 9942). Emulates the EBBWV14 Snake projection applied to ETRS89 as realized through OSNet 2009.

Area of use: United Kingdom (UK) - on or related to the rail route from Newport (Park Junction) to Ebbw Vale.

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