Available transformations
to EPSG:11119

Selected transformation

Name: Pulkovo 1942(58) to ETRS89-ROU [ETRF2000] (4)

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Replaces S-42 to ETRS89 (3) (tfm code 15993). Consistent with Transdat v3.0 to better than 0.5m. May be taken as approximate transformation Pulkovo 1942(58) to WGS 84 - see code 15995.
