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

From Felix Hartmann extremecarver at gmail.com on Fri Mar 23 08:50:00 GMT 2018

Well all the problems about problematic arcs so far came up from a
combination of two things:
a) my style creates two additional ways (bit different
road_class/road_speed based on input) if the following is met: route
relation hiking, bicycle or mtb | ( mtb:scale>0 & mtb:scale<5) |
class:bicycle>1. Additionally if a road is oneway - and it's a low level
road (so neither motorway,trunk,primary,secondary,tertiary) - and oneway, a
low class/speed non oneway road is added as well (intention to have lower
priority against the oneway than driving with the oneway direction. Also
additionally if bicycle lane against the traffic flow is possible, it will
create a line against the oneway.
b) mistakes in OSM data where wrongly several objects lie on top of each

Sorry my computer crashed yesterday evening, and I cannot boot it right
now. Seems my Mainboard is dead. So I probably won't have possibilities for
testing before Monday or Tuesday.
