Official EPSG transformation from ETRS89-NOR [EUREF89] to ETRS89-NOR [EUREF89] + NN2000 height

The EPSG Geodetic Parameter Dataset defines 1 transformation between ETRS89-NOR [EUREF89] (EPSG:10874) and ETRS89-NOR [EUREF89] + NN2000 height (EPSG:5942). Its parameters, accuracy and area of use are listed below.

ETRS89-NOR [EUREF89] to ETRS89-NOR [EUREF89] + NN2000 height (1)

EPSG:9593±0.02 m
Method:
Geog3D to Geog2D+GravityRelatedHeight (Gravsoft)
Area of use:
Norway - onshore
Scope:
Reversible geoid model transformation.

Grid file: HREF2018B_NN2000_EUREF89.bin

Reversible alternative to ETRS89-NOR [EUREF89] to NN2000 height (1) (code 9485). The interpolation CRS is EUREF89 but using any realization of ETRS89 including ensemble-based EPSG:4258 is adequate for grid interpolation.

Frequently asked questions

How accurate is converting ETRS89-NOR [EUREF89] to ETRS89-NOR [EUREF89] + NN2000 height?
The most accurate official EPSG transformation between these systems is accurate to about ±0.02 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation (including the grid-shift files listed below) in a desktop GIS.
Does my data leave the browser when I use this converter?
No. All coordinate transformations are computed locally in your browser using proj4js. The coordinates you enter are never transmitted to any server.
