Geodetic CRS: Katanga 1955
Datum: Katanga 1955
Ellipsoid: Clarke 1866
Prime meridian: Greenwich
Data source: EPSG
Information source: SD Geomatique.
Revision date: 2020-03-14
Scope: (null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.
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.
Method: Molodensky-Badekas (CF geog2D domain)
Area of use: The Democratic Republic of the Congo (Zaire) - Katanga - Likasi-Lubumbashi area.
