Frequently Asked Questions
How do I convert ETRS89-FRA [RGF93 v2] to ETRS89-FRA [RGF93 v2b] coordinates?
Use the coordinate transformation tool above to convert ETRS89-FRA [RGF93 v2] (EPSG:9777) to ETRS89-FRA [RGF93 v2b] (EPSG:9782). Enter your source coordinates and click Transform. This uses the Position Vector transformation (geog2D domain) method with 0.005m accuracy.
How do I transform ETRS89-FRA [RGF93 v2] to ETRS89-FRA [RGF93 v2b] using Proj4js?
Use proj4.defs to define both EPSG:9777 and EPSG:9782, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the ETRS89-FRA [RGF93 v2] to ETRS89-FRA [RGF93 v2b] transformation?
This transformation (EPSG:9788) has an accuracy of 0.005m using the Position Vector transformation (geog2D domain) method. Area of use: France.
