Convert coordinates from Beduaram (EPSG:4213) to WGS 84 (EPSG:4326) — official EPSG transformation parameters, accuracy and area of use, with a free in-browser converter.
The EPSG Geodetic Parameter Dataset defines 2 transformations between Beduaram (EPSG:4213) and WGS 84 (EPSG:4326). Each applies to a specific area — pick the one whose area of use covers your data.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | -106 | metre |
| Y-axis translation(ty) | -87 | metre |
| Z-axis translation(tz) | 188 | metre |
Used by Elf / CGG between December 1991 and March 1992. Probably derived from results of concatenated tfm Beduaram to WGS 84 (1) (code 8634).
Derived via WGS72BE. Can be used as a single position vector transformation with parameter values of dX = -101 m, dY = -111 m, dZ = +188.9 m, rX = rY = 0 sec, rZ = 0.814 sec, dS = -0.38 ppm
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4213", "EPSG:4326", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
