Convert coordinates from WGS 84 (G2139) (EPSG:9753) to ITRF2014 (EPSG:7789) — official EPSG transformation parameters, accuracy and area of use, with a free in-browser converter.
The EPSG Geodetic Parameter Dataset defines 1 transformation between WGS 84 (G2139) (EPSG:9753) and ITRF2014 (EPSG:7789). Its parameters, accuracy and area of use are listed below.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | 0 | millimetre |
| Y-axis translation(ty) | 0 | millimetre |
| Z-axis translation(tz) | 0 | millimetre |
| X-axis rotation(rx) | 0 | milliarc-second |
| Y-axis rotation(ry) | 0 | milliarc-second |
| Z-axis rotation(rz) | 0 | milliarc-second |
| Scale difference(ds) | 0 | parts per billion |
Scale difference in ppb where 1/billion = 1E-9 or nm/m.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:9753", "EPSG:7789", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
