Egypt Gulf of Suez S-650 TL

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

Selected transformation

Method: Geocentric translations (geog2D domain)

Remarks: Sometime referred to as "Egypt 1907 to WGS 84". However, application to WGS 84 coordinates of the reverse of this tfm results in Gulf of Suez S-650 TL, not Egypt 1907, position. Gulf of Suez S-650 TL and Egypt 1907 CRSs differ by some 20 metres.
