Ok, but you have to make sure that the house number belongs to that street, else you may assign the number to multiple streets. > > This would mean that you may have to keep around a lot of information > around for longer than if you did the housenumber step early on. > I don't know the answer of the best way to do it. I think this is a general point. If I got this right, mkgmap is doing a lot of complex calculations more than once. At some execution point, ways are split, at other points, ways are re-combined, sometimes distances are calculated, sometimes nearest nodes are searched. Maybe it is possible to find a good data structure (e.g. the quadtree used in LocationHook) that can be kept to aid such calculations? > ..Steve > _______________________________________________ > mkgmap-dev mailing list > mkgmap-dev at lists.mkgmap.org.uk > http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev -------------- next part -------------- An HTML attachment was scrubbed...
