Parameter vales are from CI1979 to WGS 84 (1) (code 1081) assuming that WGS 84 is equivalent to NZGD2000 within the accuracy of the transformation.
Frequently Asked Questions
How do I convert Chatham Islands 1979 to NZGD2000 coordinates?
Use the coordinate transformation tool above to convert Chatham Islands 1979 (EPSG:4673) to NZGD2000 (EPSG:4167). Enter your source coordinates and click Transform. This uses the Coordinate Frame rotation (geog2D domain) method with 2m accuracy.
How do I transform Chatham Islands 1979 to NZGD2000 using Proj4js?
Use proj4.defs to define both EPSG:4673 and EPSG:4167, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the Chatham Islands 1979 to NZGD2000 transformation?
This transformation (EPSG:1082) has an accuracy of 2m using the Coordinate Frame rotation (geog2D domain) method. Area of use: New Zealand - Chatham Islands group.
