Geodetic CRS: TM75
Datum: Geodetic Datum of 1965
Ellipsoid: Airy Modified 1849
Prime meridian: Greenwich
Data source: OGP
Information source: Ordnance Survey Ireland via EuroGeographics; http://crs.bkg.bund.de/crs-eu/
Revision date: 2003-06-27
Scope: For applications to an accuracy of 1 metre.
Remarks: TM75 is based on the geodetic datum of 1965 which should not be confused with the mapping adjustment of 1965 (TM65). May be taken as approximate transformations TM75 to WGS 84, TM65 to WGS 84 and OSNI 1952 to WGS 84 - see codes 1954, 1641 and 1955.
Method: Position Vector transformation (geog2D domain)
Area of use: Ireland - onshore. United Kingdom (UK) - Northern Ireland (Ulster) - onshore.
