Another interesting example are polygons like this: http://www.openstreetmap.org/way/400182030
Polygon geometry is fine here, but it has one pointless node close to one of the nodes. Pointless because it does not influence the final geometry of the polygon. And if you look around there are a lot of such buildings with pointless nodes. I would say almost every building has them... -- Tomas _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
