EPSG:10215

ETRS89 to GWWAB22-IRF (1)

Attributes

Geodetic CRS: ETRS89

Datum: European Terrestrial Reference System 1989 ensemble

Data source: EPSG

Information source: Network Rail.

Revision date: 2023-01-12

Scope: Engineering survey and topographic mapping for railway applications.

Remarks: In conjunction with the GW22-LCC map projection (code 10211) applied to GWWAB22-IRF (code 10214), emulates the GWWAB22 Snake projection. Applied to ETRS89 (as realized through the OSNet v2009) defines GWWAB22-IRF hence is errorless.

Method: NTv2

Area of use: United Kingdom (UK) - on or related to the rail routes around Cardiff and the valleys.
