NZGD49 / North Taieri Circuit

Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: These parameter values are taken from NZGD49 to NZGD2000 (2) (code 1701) and assume that NZGD2000 and WGS 84 are coincident to within the accuracy of the transformation. For improved accuracy use NZGD49 to WGS 84 (4) (code 1670).
