Hi Felix, it probably depends on the --levels option, means, how many levels you put into a gmapsupp.
And yes, I don't have a clear idea how to detect parallel lines which will / should collapse into one line.

The main problem I feel is now that sometimes highways you can see both directions apart - while before this was less rare - or lost in the jaggedness. --x-simplify-filter-line-errors=23:3.6,22:4.2,21:5.4,20:6,19:7,18:7.5,16:8,15:9 --x-simplify-filter-polygon-errors=23:4.6,22:7,21:8,20:9,15:10 --polygon-size-limits=24:16,23:14,22:12,21:11,20:10,19:9,18:8,17:7,16:6,15:5,14:4,13:3,12:2,11:0,10:0 seems to give pretty nice results - and much faster on my Garmin 600 at lower resolutions. I guess those highways with dual directions are much harder to solve...

Next planned step is to check if the simplify4.patch still improves things and maybe improve it further.

I'm waiting for updates on the new branch to test things. I still feel level>=1, the higher the level the less exact it needs to be. It just needs to be small and beautiful from resolution 21 and lower. While actually driving/riding/walking you will always use 24-22 (even 22 only in car I feel. Maybe 21 on highways). Those levels are important on PC and GPS device for orientation. And while actual switchback turns on a road would be quite worthwhile, those zig zag things aren't. _______________________________________________ mkgmap-dev mailing list [email protected]<mailto:[email protected]> https://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev -- Felix Hartman - Openmtbmap.org & VeloMap.org _______________________________________________ mkgmap-dev mailing list [email protected] https://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
