[QGIS-ZA-user] NTv2 Datum Transformation Grid

[Craig Leat]

Hi,

I have SG Diagrams using the Cape Datum and I need to transform these to
the Hartebeesthoek94 datum using the NTv2 datum transformation grid. QGIS
can take a custom proj definition with the option
+nadgrids=nameoftheNTv2file.gsb

Does anyone know where I can obtain the NTv2 grid (the .gsb file)? I don't
know if there is one file for the whole country or one for each degree
square.

Regards

Craig
