EPSG:4068

Katanga 1955 to WGS 84 (2)

Attributes

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.

Description: (-102.283, -10.277, -257.396, -3.976, -0.002, -6.203, 12.315)
