Frequently Asked Questions
How do I convert NEA74 Noumea to RGNC91-93 coordinates?
Use the coordinate transformation tool above to convert NEA74 Noumea (EPSG:4644) to RGNC91-93 (EPSG:4749). Enter your source coordinates and click Transform. This uses the Coordinate Frame rotation (geog2D domain) method with 0.1m accuracy.
How do I transform NEA74 Noumea to RGNC91-93 using Proj4js?
Use proj4.defs to define both EPSG:4644 and EPSG:4749, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the NEA74 Noumea to RGNC91-93 transformation?
This transformation (EPSG:15889) has an accuracy of 0.1m using the Coordinate Frame rotation (geog2D domain) method. Area of use: New Caledonia - Grande Terre - Noumea.
