Reversible alternative to ETRS89-NOR [EUREF89] to CD Norway depth (2) (code 10130). Replaces ETRS89-NOR [EUREF89] to ETRS89-NOR [EUREF89] + CD Norway depth (1) (code 9885). Replaced by ETRS89-NOR [EUREF89] to ETRS89-NOR [EUREF89] + CD Norway depth (3) (code 10505). 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] + CD Norway depth?
The most accurate official EPSG transformation between these systems is accurate to about ±0.5 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.
