Frequently Asked Questions

How do I convert RT90 to ETRS89 coordinates?

Use the coordinate transformation tool above to convert RT90 (EPSG:4124) to ETRS89 (EPSG:4258). Enter your source coordinates and click Transform. This uses the Coordinate Frame rotation (geog2D domain) method.

How do I transform RT90 to ETRS89 using Proj4js?

Use proj4.defs to define both EPSG:4124 and EPSG:4258, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
