[Qgis-user] How to georeference vector data

[Andreas Neumann]

Hi Jacob,

It is not possible yet.

It is also on my wish-list. As soon as we can properly import DXF file
this will be an urgent need - as many DXF files lack proper georeferencing.

I hope that we can develop this functionality in QGIS 2.1 - if you are
able to (partially) finance such functionality it would be great.
