Convert coordinates from La Canoa (EPSG:4247) 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 La Canoa (EPSG:4247) 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) | -273.5 | metre |
| Y-axis translation(ty) | 110.6 | metre |
| Z-axis translation(tz) | -357.9 | metre |
Parameter values estimated accuracy: ± 2.0m; ± 2.7m; ± 1.3m respectively. Also used for PSAD56 to WGS 84 transformations.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | -270.933 | metre |

| X-axis rotation(rx) | -5.266 | arc-second |
| Y-axis rotation(ry) | -1.238 | arc-second |
| Z-axis rotation(rz) | 2.381 | arc-second |
| Scale difference(ds) | -5.109 | parts per million |
| Pivot X(px) | 2464351.59 | metre |
| Pivot Y(py) | -5783466.61 | metre |
| Pivot Z(pz) | 974809.81 | metre |
Parameter values are from La Canoa to REGVEN (1) (code 1771) assuming that REGVEN is equivalent to WGS 84 within the accuracy of the transformation.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4247", "EPSG:4326", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
