2 branches that use the WFS :
https://github.com/iTowns/itowns2/tree/WFS2_rebased --> There are all
building in France, and on the city of Lyon you can see datas vector in
the form of Lines and Points
https://github.com/iTowns/itowns2/commits/kmlLoader --> There is draping
a vector feature on the ground.(Example is located in the Alpes). You
can activate picking zone in GUI.
