Convert coordinates from Campo Inchauspe (EPSG:4221) 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 Campo Inchauspe (EPSG:4221) 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) | -154.5 | metre |
| Y-axis translation(ty) | 150.7 | metre |
| Z-axis translation(tz) | 100.4 | metre |
Derived through ties at 2 stations (Cerro Colorado and Chihuido Sur) to 4 IGS stations in February 1995
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | -148 | metre |
| Y-axis translation(ty) | 136 | metre |
| Z-axis translation(tz) | 90 | metre |
Derived at 20 stations. Accuracy 5m in each axis.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4221", "EPSG:4326", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
