GDA94 / Australian Albers

Selected transformation

Method: NTv2

Grid Files: GDA94_GDA2020_conformal.gsb

Remarks: Gives identical results to Helmert transformation GDA94 to GDA2020 (1) (code 8048). See GDA94 to GDA2020 (2) (code 8447) for alternative with local distortion modelling included. GDA2020 Technical Manual and fact sheet T1 give guidance on which to use.
