Transformation

OSNI 1952 to WGS 84 (1)

Covered area

SimpleMap

WGS84 bounds:
-8.18 53.96
-5.34 55.36

Attributes

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.

Description: (482.5, -130.6, 564.6, -1.042, -0.214, -0.631, 8.15)
