Frequently Asked Questions

How do I convert ED50(ED77) to WGS 84 coordinates?

Use the coordinate transformation tool above to convert ED50(ED77) (EPSG:4154) to WGS 84 (EPSG:4326). Enter your source coordinates and click Transform. This uses the Geocentric translations (geog2D domain) method with 0.5m accuracy.

How do I transform ED50(ED77) to WGS 84 using Proj4js?

Use proj4.defs to define both EPSG:4154 and EPSG:4326, then call proj4(source, target, [x, y]) to convert coordinates programmatically.

What is the accuracy of the ED50(ED77) to WGS 84 transformation?

This transformation (EPSG:1858) has an accuracy of 0.5m using the Geocentric translations (geog2D domain) method. Area of use: Iran - Kharg Island.
