EPSG:7711

ETRS89 to ODN height (2)

Attributes

Geodetic CRS: ETRS89

Datum: European Terrestrial Reference System 1989 ensemble

Data source: EPSG

Information source: Ordnance Survey of Great Britain.

Revision date: 2021-02-05

Scope: Derivation of gravity-related heights from GNSS observations.

Remarks: OSGM15 supersedes OSGM02 geoid model. Replaces ETRS89 to Newlyn height (1) (tfm code 10021). For reversible alternative to this transformation see ETRS89 to ETRS89 + ODN height (2) (code 9587).

Method: Geographic3D to GravityRelatedHeight (OSGM-GB)

Area of use: United Kingdom (UK) - Great Britain onshore - England and Wales - mainland; Scotland - mainland and Inner Hebrides.
