Official EPSG transformation from ETRF2014 to NKG_ETRF14

The EPSG Geodetic Parameter Dataset defines 1 transformation between ETRF2014 (EPSG:8401) and NKG_ETRF14 (EPSG:10805). Its parameters, accuracy and area of use are listed below.

ETRF2014 to NKG_ETRF14 (1)

EPSG:10809±0.003 m
Method:
Geocentric translations using NEU velocity grid (gtg)
Area of use:
Europe - Nordic and Baltic countries
Scope:
Geodesy.

Grid file: NKG_RF17vel.tif

Nordic Geodetic Commission (NKG) 2020 transformation. Accuracy estimated as 0.1, 0.1, and 0.4 mm/year for the North, East, and Up components, respectively. Because the difference in coordinates between ETRF2014 and NKG_ETRF14 is small (under a decimetre), although the interpolation CRS is given as ETRF2014, any realization of ETRS89 (including NKG_ETRF14) may be used as the interpolation CRS. The source CRS ETRF2014 is a dynamic CRS and the coordinate epoch for the coordinates referenced to it is a user-defined input.

Frequently asked questions

How accurate is converting ETRF2014 to NKG_ETRF14?
The most accurate official EPSG transformation between these systems is accurate to about ±0.003 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.
