Convert coordinates from S-JTSK (EPSG:4156) to S-JTSK/05 (EPSG:5228) — official EPSG transformation parameters, accuracy and area of use, with a free in-browser converter.
The EPSG Geodetic Parameter Dataset defines 1 transformation between S-JTSK (EPSG:4156) and S-JTSK/05 (EPSG:5228). Its parameters, accuracy and area of use are listed below.
| Parameter | Value | Unit |
|---|---|---|
| Latitude offset | 0 | arc-second |
| Longitude offset | 0 | arc-second |
S-JTSK/05 is derived from the R05 realisation of ETRS89 and constrained to be coincident with S-JTSK.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4156", "EPSG:5228", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
