EPSG:10194

CNH22 Grid

Attributes

Unit: metre

Geodetic CRS: CNH22-IRF

Datum: CNH22 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 CNH22-IRF (1) (code 10192) and map projection CNH22-LCC (code 10193) emulates the CNH22 Snake projection applied to ETRS89 as realized through OSNet 2009. Also replaces CNH1_2019 and CNH3_2015.

Area of use: United Kingdom (UK) - on or related to the rail route from Crewe via Chester to Holyhead.

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

Center coordinates
212882.7 494118.03

Projected bounds:
131353.88 469634.53
294414.84 519293.67

WGS84 bounds:
-4.71 53.02
-2.28 53.46
