Selected transformation

Method: NTv2

Grid Files: National 84 (02.07.01).gsb

Remarks: Replaces AGD84 to GDA94 (4) (code 1593) which itself replaced variant 3 (code 1559). Input expects longitudes to be + west; EPSG GeogCRS AGD84 (code 4203) and GDA94 (code 4283) both have longitudes positive east. May be used as tfm to WGS 84 - see 15785
