Geodetic CRS: OSNI 1952
Datum: OSNI 1952
Ellipsoid: Airy 1830
Prime meridian: Greenwich
Data source: OGP
Information source: OGP
Revision date: 2004-04-09
Scope: For applications to an accuracy of 1 metre.
Remarks: Parameter values from TM75 to ETRS89 (2) (code 1953). Assumes each pair of (i) OSNI 1952 and TM75, and (ii) ETRS89 and WGS 84, can be considered the same to within the accuracy of the transformation.
Method: Position Vector transformation (geog2D domain)
Area of use: United Kingdom (UK) - Northern Ireland (Ulster) - onshore.
