Method: Position Vector transformation (geog2D domain)
Remarks: Derived via WGS 72BE. Original transformation derived by GSI in 1980-81. The GSI memo incorrectly gave the parameters as from WGS 72 to Beijing 1954, but it has been determined by the OGP that the memo should have stated from Beijing 1954 to WGS 72BE.
Information source: ExxonMobil. Also Total via SSB in 1981.
