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

From Felix Hartmann extremecarver at gmail.com on Wed Feb 28 19:54:47 GMT 2018

Hi Gerd
will do so tomorrow - cannot get onto my server since 2 hours (if I still
cannot get on the server I will compile locally on Friday).

As for the mail - yes I read it and replied in here.
I think the order for most would be the opposite - throw away the first
roads, not the last! Usually you would first put in routes, bridges and so
on into your map - then maybe lines just for visualisation - all with
continue, and then finally put in the road itself without continue.
For my maps the best approach in doubt would be:
1. check if one segment is completely double (same type - fully covered by
the same type).
2. Throw away 0x13 (I use this invisibly for routing)
3. Throw away those roads created first if still needed.
