Transform Coordinates

Remarks

Concatenation of CTs 1150 and 8048 through GDA94. Scale difference in ppb where 1/billion = 1E-9. See WGS 84 to GDA2020 (4) (CT code 9691) for alternative for Australia including distortion model.

Frequently Asked Questions

How do I convert WGS 84 to GDA2020 coordinates?

Use the coordinate transformation tool above to convert WGS 84 (EPSG:4326) to GDA2020 (EPSG:7844). Enter your source coordinates and click Transform. This uses the Coordinate Frame rotation (geog2D domain) method with 3m accuracy.

How do I transform WGS 84 to GDA2020 using Proj4js?

Use proj4.defs to define both EPSG:4326 and EPSG:7844, then call proj4(source, target, [x, y]) to convert coordinates programmatically.

What is the accuracy of the WGS 84 to GDA2020 transformation?

This transformation (EPSG:9690) has an accuracy of 3m using the Coordinate Frame rotation (geog2D domain) method. Area of use: Australia - GDA.
