Katanga 1955 / Katanga Gauss zone C

The Democratic Republic of the Congo (Zaire) , accuracy 1.0 m, code 4068 (default) [7]
The Democratic Republic of the Congo (Zaire) , accuracy 1.5 m, code 4066 [3]

Selected transformation

Method: Molodensky-Badekas (CF geog2D domain)

Remarks: Parameter values taken from Katanga 1955 to RGRDC 2005 (2) (code 4067) assuming that RGRDC 2005 is equivalent to WGS 84 within the accuracy of the transformation.
