Cape / Lo19

Available transformations
to EPSG:4326
EPSG:4326 - WGS 84

Selected transformation

Method: Geocentric translations (geog2D domain)

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.
