Official EPSG transformation from ITRF2014 to SWEREF99

The EPSG Geodetic Parameter Dataset defines 1 transformation between ITRF2014 (EPSG:7789) and SWEREF99 (EPSG:4976). Its parameters, accuracy and area of use are listed below.

ITRF2014 to SWEREF99 (1)

EPSG:10824±0.004 m
Method:
Concatenated operation
Area of use:
Sweden
Scope:
Geodesy, topographic mapping.
  1. ITRF2014 to ETRF2014 (2) (null)
  2. ETRF2014 to NKG_ETRF14 (1) (null)
  3. NKG_ETRF14 to SWEREF99 (1) (null)

The coordinate epoch (in years) of the coordinates referenced to the source CRS (ITRF2014) is user-defined and is used as the source epoch in step 2. For coordinates originating before 2021-02-07, the NKG2008 transformation should be used.

Frequently asked questions

How accurate is converting ITRF2014 to SWEREF99?
The most accurate official EPSG transformation between these systems is accurate to about ±0.004 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation 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.
