Method: Position Vector transformation (geog2D domain)
Remarks: Parameter values taken from TM65 to ETRS89 (2) (code 1953). Assumes ETRS89 and WGS 84 can be considered the same to within the accuracy of the transformation.
Information source: OGP
Revision date: 2003-06-27
Unit: degree (supplier to define representation)
Geodetic CRS: TM75
Datum: Geodetic Datum of 1965
Ellipsoid: Airy Modified 1849
Prime meridian: Greenwich
Data source: OGP
Information source: "The Irish Grid - A Description of the Co-ordinate Reference System" published by Ordnance Survey of Ireland, Dublin and Ordnance Survey of Northern Ireland, Belfast.
Revision date: 2004-01-06
Scope: Basis for topographic mapping.
Remarks: Uses Geodetic Datum of 1965 which should not be confused with the 1965 adjustment (TM65, datum code 6299 and CRS code 4299). Replaces OSNI52 (CRS code 4188) and TM65 (CRS code 4299). Replaced by IRENET95 (CRS code 4173).
