Engineering survey and topographic mapping for railway applications.
Intermediate CRS created in 2022 to assist the emulation of the ETRS89 / SMITB20 SnakeGrid projected CRS through transformation ETRS89 to SMITB20-IRF (1) (code 10273) used in conjunction with the SMITB20-TM map projection (code 10274).
United Kingdom (UK) - on or related to the rail route from Okehampton to Penstone.
Ellipsoidal 2D CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree
