Selected transformation

Australia

code 1669

Accuracy 1.0 m
7 parameters

Method: Coordinate Frame Rotation (geog2D domain)

Remarks: Parameter values from AGD84 to GDA94 (2) (code 1280). Assumes GDA94 and WGS 84 can be considered the same to within the accuracy of the transformation. Replaces AGD84 to WGS 84 (2) (code 1236). Note: AGD84 officially adopted only in Qld, SA and WA.
