S-JTSK [JTSK03] / Krovak East North

Available transformations
to EPSG:4326

Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Parameter values taken from S-JTSK [JTSK03] to ETRS89 (1) (code 8367) assuming that ETRS89 (ETRF2000 realization) is coincident with WGS 84 within the accuracy of the transformation. Within the 1m accuracy of this transformation, it is reversible.
