Convert coordinates from Chua (EPSG:4224) to SIRGAS 2000 (EPSG:4674) — official EPSG transformation parameters, accuracy and area of use, with a free in-browser converter.
The EPSG Geodetic Parameter Dataset defines 1 transformation between Chua (EPSG:4224) and SIRGAS 2000 (EPSG:4674). Its parameters, accuracy and area of use are listed below.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | -144.35 | metre |
| Y-axis translation(ty) | 242.88 | metre |
| Z-axis translation(tz) | -33.2 | metre |
Mandatory for SICAD use. Replaces Chua to WGS 84 (2) (code 3972). May be used as a tfm to WGS 84 - see tfm code 4834.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4224", "EPSG:4674", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
