Name: TM65 to WGS 84 (1)
Method: Geocentric translations (geog2D domain)
Remarks: Derived at 7 stations.
Information source: U.S. Defense Mapping Agency TR8350.2 December 1987.
Revision date: 1996-10-18
Unit: degree (supplier to define representation)
Geodetic CRS: TM65
Datum: TM65
Ellipsoid: Airy Modified 1849
Prime meridian: Greenwich
Data source: EPSG
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: 2006-01-16
Scope: Basis for topographic mapping in Republic of Ireland between 1965 and 1975; for scientific purposes only in Northern Ireland.
Remarks: Replaced by 1975 Mapping Adjustment alias TM75 (CRS code 4300). Not to be confused with the Geodetic Datum of 1965 (datum code 6300) which is used by TM75.
