Convert coordinates from POSGAR 2007 (EPSG:5340) 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 POSGAR 2007 (EPSG:5340) 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) | -0.41 | metre |
| Y-axis translation(ty) | 0.46 | metre |
| Z-axis translation(tz) | -0.35 | metre |
Derived as average at all points common between the POSGAR 94 and POSGAR 2007 networks. Accuracy 0.1m in 1994 increasing by approximately 1.5cm per year due to tectonic plate motion.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | 0 | metre |
| Y-axis translation(ty) | 0 | metre |
| Z-axis translation(tz) | 0 | metre |
Approximation at the +/- 1m level assuming that POSGAR 2007 is equivalent to WGS 84.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:5340", "EPSG:4326", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
