Geodetic CRS: ETRS89
Datum: European Terrestrial Reference System 1989 ensemble
Data source: EPSG
Information source: Norwegian Mapping Authority (Statens Kartverk).
Revision date: 2023-11-30
Scope: Derivation of depths from GNSS observations.
Remarks: For reversible alternative to this transformation see ETRS89 to ETRS89 + CD Norway depth (1) (code 9885). Replaced by ETRS89 to CD Norway depth (2) (model "CD Norway 2021b", code 10130).
Method: Geographic3D to Depth (Gravsoft)
Area of use: Norway - inshore and nearshore.
