Selected transformation

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.

Revision date: 2020-03-14

Attributes

Unit: metre

Geodetic CRS: Beijing 1954

Datum: Beijing 1954

Ellipsoid: Krassowsky 1940

Revision date: 2002-06-22

Scope: Topographic mapping (medium scale).

Remarks: Also found with truncated false easting - see Beijing 1954 / Gauss-Kruger CM 111E (code 24159). Replaced by Xian 1980 / Gauss-Kruger zone 19 (code 2333).

Area of use: China - onshore between 108°E and 114°E.

Coordinate system: Cartesian 2D CS. Axes: northing, easting (X,Y). Orientations: north, east. UoM: m.
