Subject: [QGIS-ZA-user] NTv2 Datum Transformation Grid

 

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
