Frequently Asked Questions

How do I convert ED87 to ETRS89 coordinates?

Use the coordinate transformation tool above to convert ED87 (EPSG:4231) to ETRS89 (EPSG:4258). Enter your source coordinates and click Transform. This uses the Position Vector transformation (geog2D domain) method with 0.3m accuracy.

How do I transform ED87 to ETRS89 using Proj4js?

Use proj4.defs to define both EPSG:4231 and EPSG:4258, then call proj4(source, target, [x, y]) to convert coordinates programmatically.

What is the accuracy of the ED87 to ETRS89 transformation?

This transformation (EPSG:4078) has an accuracy of 0.3m using the Position Vector transformation (geog2D domain) method. Area of use: Europe - west.
