KKJ / Finland zone 4

Available transformations
to EPSG:4326
EPSG:4326 - WGS 84

Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Parameter values from KKJ to ETRS89 (2) (code 10098). Assumes ETRS89 and WGS 84 can be considered the same to within the accuracy of the transformation. Replaces KKJ to WGS 84 (1) (code 1639).
