Available transformations
to EPSG:4258
EPSG:4258 - ETRS89

Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: In most areas accuracy is approximately 0.5m although in some areas it is in the order of 2m. May be taken as approximate transformation KKJ to WGS 84 - see code 10099. Replaces KKJ to ETRS89 (1) (code 1638).
