Convert coordinates from Manoca 1962 (EPSG:4193) 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 Manoca 1962 (EPSG:4193) 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) | -70.9 | metre |
| Y-axis translation(ty) | -151.8 | metre |
| Z-axis translation(tz) | -41.4 | metre |
Derived at two points, checked at a third by Stolt Comex Seaway and Geoid for Elf.
Derived via WGS 72BE. Can be implemented as a single position vector transformation with parameter values of dX = -56.7 m, dY = -171.8 m, dZ = -38.7 m, rX = rY = 0 sec, rZ = 0.814 sec, dS = -0.38 ppm.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4193", "EPSG:4326", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
