I'm pretty sure it will be published with coordinates. There are existing laws with coordinates in them, at least for borders between municipalities. But it's hard to find them all since only the recent changes are made available digitally. > I wonder what happens when the river or stream used as a borderline > by OSM changes its course by itself. There are defentily cases where the border is the historic path of a river, and either the river changed by itself or man altered it's path but that the border stayed. But it's not only rivers. Roads are often also the border and might later be widened, straighten out and so on. You can do 2 things when currently mapping them and you don't have official coordinates: - Re-use the existing nodes, nodes end up in 2 ways - Use other points for them, they don't share nodes In the first case you of course need to be careful when moving such a node. But we might not know better where the border really is so it's often easier to map re-use the nodes.
