EPSG:1129

Cape to WGS 84 (2)

Attributes

Geodetic CRS: Cape

Datum: Cape

Ellipsoid: Clarke 1880 (Arc)

Prime meridian: Greenwich

Data source: EPSG

Information source: Private Communication, Directorate of Surveys and Land Information, Cape Town.

Revision date: 2021-09-23

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 are from Cape to Hartebeesthoek94 (1) (code 1504) assuming that Hartebeesthoek94 and WGS 84 are equivalent within the accuracy of the transformation. Residuals should not exceed 15 metres.

Method: Geocentric translations (geog2D domain)

Area of use: South Africa - mainland onshore.

Description: (-134.73, -110.92, -292.66, 0.0, 0.0, 0.0, 0.0)
