EPSG:6277

OSGB 1936

Attributes

Ellipsoid: Airy 1830

Prime meridian: Greenwich

Degree from Greenwich: 0

Data source: OGP

Information source: Ordnance Survey of Great Britain.

Revision date: 2016-09-29

Scope: Topographic mapping.

Remarks: The average accuracy of OSTN compared to the old triangulation network (down to 3rd order) is 0.1m. With the introduction of OSTN15, the area for OGSB 1936 has effectively been extended from Britain to cover the adjacent UK Continental Shelf.

Area of use: United Kingdom (UK) - offshore to boundary of UKCS within 49°46'N to 61°01'N and 7°33'W to 3°33'E; onshore Great Britain (England, Wales and Scotland). Isle of Man onshore.
