EPSG:20047

GDA2020 / BCSG2020

Available transformations
to EPSG:4326
No other targets exist for this CRS

Selected transformation

Method: Geocentric translations (geog2D domain)

Remarks: Approximation at the 3m level assuming WGS 84 is equivalent to GDA2020. Ignores the low accuracy of the WGS 84 ensemble and the inconsistent application of tectonic plate motion to WGS 84 data.
