EPSG:1315

OSGB36 to ED50 (1)

Attributes

Geodetic CRS: OSGB36

Datum: Ordnance Survey of Great Britain 1936

Ellipsoid: Airy 1830

Prime meridian: Greenwich

Data source: EPSG

Information source: UK Offshore Operators Association.

Revision date: 2021-03-18

Scope: Oil and gas exploration and production.

Remarks: Known as the "UKOOA landward/seaward transformation". This transformation is concatenated from OSGB36 to WGS 84 (6) (Petroleum) (code 1314) minus ED50 to WGS 84 (18) (Common Offshore) (code 1311). Accuracy better than 4m and generally better than 2m.

Method: Position Vector transformation (geog2D domain)

Area of use: United Kingdom (UK) - Great Britain - England and Wales onshore, Scotland onshore and Western Isles nearshore including Sea of the Hebrides and The Minch; Isle of Man onshore.
