Hi all, I am a bit desolated reg. this problem, maybe you have new ideas for me. I try to describe what happens: 1) The style adds a road and one or more overlay lines 2) Before housenumber processing the roads are processed by the so called RoadMerger which may connect two or more roads with similar attributes, after that there is no easy way to find the corresponding overlay lines for a road. 3) When the housenumber functions add new nodes to the road to improve the address search, these nodes may be > 1m away from the overlay line. My first approach was to change the housenumber code so that it adds only nodes which are very close to the overlay line, but that turned out to be impossible in some cases, means, we either have bad results in address search or visible line distortions. Another approach would be to add the nodes also to the overlay ways, but as I said I see no easy and performant way to find the corresponding overlay lines, as they also may have a reverse order of points. My experience tells me that I should better try to find a completely different approach for the housenumbers, but up to now there was no "heureka" . If the img format would allow to say "use this point only for address search, but not for rendering" all would be easy, but I don't think that this is possible ? So, I'll try again to fix the overlay lines using a brute search algo, maybe the performance doesn't matter as there are not so many added nodes . Gerd Gerd Petermann wrote
Hi Minko,
thanks for the picture. I think the fix is not yet catching all cases, so I'll continue working on it.
Gerd

Thanks for the fix Gerd!

I think a distance of less than 0.4 m is not visible, and nearly all calculated points are now closer than that. A binary based on r3658 is here: http://files.mkgmap.org.uk/download/287/mkgmap.jar
