[Qgis-developer] Spatialize attribute columns XY oor WKT, design choice

[Hugo Mercier]

Hi,

I've added a wiki page to discuss the design of this feature here :
http://hub.qgis.org/wiki/quantum-gis/virtual_layers

It's mainly focused on Regis' use case (create a spatial view out of X,Y
coordinates).

Feel free to comment/complete.
