[Qgis-developer] [Qgis-user] Transformation using NTv2 grids

[Andreas Neumann]

Hi,

I think the grids of the major countries should be included in QGIS 
core. E.g. the german gsb file is only 87 kb. This could easily be 
distributed with QGIS core.

It is the duty of the local QGIS user groups to come up with a solution 
for their users - either by bundling it in QGIS core or through a plugin 
or good tutorial.

It would make the life much easier for the average user.

Andreas
