The EPSG Geodetic Parameter Dataset defines 1 transformation between CSG67 (EPSG:4623) and WGS 84 (EPSG:4326). Its parameters, accuracy and area of use are listed below.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | -186 | metre |
| Y-axis translation(ty) | 230 | metre |
| Z-axis translation(tz) | 110 | metre |
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4623", "EPSG:4326", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
