The EPSG Geodetic Parameter Dataset defines 1 transformation between RGF93 v2b (EPSG:9782) and ETRS89 (EPSG:4258). Its parameters, accuracy and area of use are listed below.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | 0 | metre |
| Y-axis translation(ty) | 0 | metre |
| Z-axis translation(tz) | 0 | metre |
RGF93 v2b is a national realization of ETRS89. May be taken as approximate transformation RGF93 v2b to WGS 84 - see CT code 9792.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:9782", "EPSG:4258", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
