How does a node get to be in more than four areas?
..Steve
Good question, I was wondering that myself. It looks like with so few nodes per area, we end up with some very thin areas that for example result in the two areas on each side, plus two adjacent areas above, being included in the extended bounds/overlap if a node is in the centre of the thin area and close to the top. Here's an example of a node that wants to be in 5 areas: <node id="447665000" lat="46.0753181" lon="13.1930056" version="1" changeset="1930879" user="Stefano Salvador" uid="86130" visible="true" timestamp="2009-07-25T06:50:50Z"/> And here are the areas taken from areas.list, as generated with today's europe.osm file and running the splitter with --max-nodes=300000 (and a default overlap of 2000): 63240332: 2142208,608256 to 2148352,614400 # : 45.966797,13.051758 to 46.098633,13.183594 63240333: 2142208,614400 to 2146304,620544 # : 45.966797,13.183594 to 46.054688,13.315430 63240334: 2146304,614400 to 2148352,620544 # : 46.054688,13.183594 to 46.098633,13.315430 63240335: 2148352,608256 to 2154496,614400 # : 46.098633,13.051758 to 46.230469,13.183594 63240336: 2148352,614400 to 2154496,620544 # : 46.098633,13.183594 to 46.230469,13.315430 All the examples I've seen so far are hitting 5 areas max, but given the above I could imagine it's possible to get 6 or more too if there's an especially densely populated area on the map.
