Transformation

TM75 to WGS 84 (3)

Covered area

SimpleMap

WGS84 bounds:
-10.56 51.39
-5.34 55.43

Attributes

Geodetic CRS: TM75

Datum: Geodetic Datum of 1965

Ellipsoid: Airy Modified 1849

Prime meridian: Greenwich

Data source: OGP

Information source: U.S. Defense Mapping Agency TR8350.2 September 1987.

Revision date: 2014-11-19

Scope: For military purposes only. Accuracy 3m in each axis.

Remarks: Derived at 7 stations. TM75 is based on the geodetic datum of 1965 which should not be confused with the mapping adjustment of 1965 (TM65).

Method: Geocentric translations (geog2D domain)

Area of use: Ireland - onshore. United Kingdom (UK) - Northern Ireland (Ulster) - onshore.

Description: (506.0, -122.0, 611.0, 0.0, 0.0, 0.0, 0.0)
