ECML14_NB Grid

Attributes

Unit: metre

Geodetic CRS: ECML14_NB-IRF

Datum: ECML14_NB Intermediate Reference Frame

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: Network Rail.

Revision date: 2023-01-12

Scope: Engineering survey and topographic mapping for railway applications.

Remarks: The CRS's definition through transformation ETRS89 to ECML14_NB-IRF (1) (code 9759) and map projection ECML14_NB-TM (code 9760) emulates the ECML14_NB Snake projection applied to ETRS89 as realized through OSNet 2009 CORS.

Area of use: United Kingdom (UK) - on or related to rail routes from Newcastle Central to Ashington via Benton North Junction, and the section from Bedlington to Morpeth.

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