[Qgis-user] Transformation using NTv2 grids

Hi Marco,

Is this already in 2.1?
If yes, where could one find it?


Would it be possible to define a "Custom CRS" for the source CRS containing the 
nadgrids-stuff for doing ntv2 transformation in QGIS 2.0.1?

For example GK3:
"+proj=tmerc +lat_0=0 +lon_0=9 +k=1.000000 +x_0=3500000 +y_0=0 +ellps=bessel 
+units=m +nadgrids=BETA2007.gsb +wktext" 


cheers,
  robert
