Engineering survey and topographic mapping for railway applications.
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.
United Kingdom (UK) - on or related to the rail route from Crewe via Chester to Holyhead.
