[mkgmap-dev] Bug in Road Merging - actually doubling roads.

From Felix Hartmann extremecarver at gmail.com on Sun Mar 11 14:13:06 GMT 2018

Hi Gerd,
oh - I had a different layout in gpsmapedit with 0x13 set to invisible and
not used to opening gpsmapedit from my laptop. So the map was actually

is now fine - though of course the visible rendering is not really
representing how it looks in reality - but broken routing is fixed.

as you said is still spiking - and actually with my style in that case also
wrongly ending up in 6 routable lines. For me really a simple remove all
semi connected ways at minimum length filter would be fine. I would just
remove clutter of micromapping.

As for the roundabouts.
1. https://www.openstreetmap.org/way/208976154
looks fine - just strange that way https://www.openstreetmap.
org/way/447282006 is not merged - all the others are merged.

2. https://www.openstreetmap.org/way/312642720
a bit strange that it gets split into 2 ways. Routing seems fine. (the NNE
section of the roundabout between the exit and entry is separated)

3. https://www.openstreetmap.org/way/148634420
actually looks much better then with older versions of mkgmap. Looks pretty
round - with a 3 month old mkgmap version (sorry don't have unpatched to
compare) it was not very round. Routing is fine.
Although here the north section is split off into a seperate way- it this a
need for roundabouts?
