Sorry Sam, I don't want to argue with anybody.

Tyler converted each province as separate .osm files. michel gilbert did a great job at converting the province boundaries and importing. note: it was only 1 person who imported all provincial boundaries. its commonly agreed that boundaries, and the enire 'boundary web' should actually consist of only 1 strand for each boundary line. think of it like a spiders web. if you were to paint inside each 'whole' you actually go over each strand 2 or more times in the process. unlike the whysical world, where thereis a boundary line, its clear that on 1 side is the municapality of 1 area and the other is of the next town/area. there needs not to be a 'nutral zone'. however, those rules are not set in stone, all boundaries dont need to be a relation, i prefer that the lowest boundary level (local community) gets mapped as polygons, then the next level up gets mapped as relations, so it just uses the same 'strand' Complexity which is better?
