Official EPSG transformation from GDA2020 to WGS 84 (Transit)

The EPSG Geodetic Parameter Dataset defines 1 transformation between GDA2020 (EPSG:7842) and WGS 84 (Transit) (EPSG:7815). Its parameters, accuracy and area of use are listed below.

GDA2020 to WGS 84 (Transit) (1)

EPSG:8887±3 m

Method:: Geocentric translations (geocentric domain)
Area of use:: Australia - GDA
Scope:: (null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.

Parameter	Value	Unit
X-axis translation(tx)	0	metre
Y-axis translation(ty)	0	metre
Z-axis translation(tz)	0	metre

Approximation at the 3m level assuming WGS 84 (Transit) is equivalent to ITRF2014 within the accuracy of the transformation.

Frequently asked questions

How accurate is converting GDA2020 to WGS 84 (Transit)?: The most accurate official EPSG transformation between these systems is accurate to about ±3 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.
