Transform Coordinates
Remarks
This transformation is for users wanting to apply a 7-parameter conformal transformation from AGD66 to GDA2020 in the ACT.
Frequently Asked Questions
How do I convert AGD66 to GDA2020 coordinates?
Use the coordinate transformation tool above to convert AGD66 (EPSG:4202) to GDA2020 (EPSG:7844). Enter your source coordinates and click Transform. This uses the Coordinate Frame rotation (geog2D domain) method with 0.05m accuracy.
How do I transform AGD66 to GDA2020 using Proj4js?
Use proj4.defs to define both EPSG:4202 and EPSG:7844, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the AGD66 to GDA2020 transformation?
This transformation (EPSG:9185) has an accuracy of 0.05m using the Coordinate Frame rotation (geog2D domain) method. Area of use: Australia - Australian Capital Territory.
