ED50 / TM 0 N

Available transformations
to EPSG:4326

Selected transformation

Remarks: 1990 agreement between Denmark, Germany, Great Britain, Netherlands and Norway. Replaces 1981 6-nations agreement between ED50 and WGS72 or WGS72BE. Only actively used offshore Norway but see ED50 to WGS 84 (24) (code 1613) for simpler transformation.

Information source: Norwegian Mapping Authority publication 1990:1 "The transformation between ED50 and WGS84 for exploration purposes in the North Sea".
