[Qgis-user] google wms

[Andreas Neumann]

Another restriction is the fixed projection of the tiles and the licence
restrictions.

However, given that in some regions, Google maps is one of the very few
data sources available with ease, it is probably worth the effort.

I am not sure if the Google maps licence would allow the embedding of
Google maps data in Desktop GIS?
