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

Thu Mar 1 11:33:04 GMT 2018

Hi Felix,

okay, now I have it. Doesn't help much because the debug routine simply
creates OSM ways for the data, and since your style creates many duplicated ways JOSM cannot handle the data:-(
Maybe I'll change the debug code to create unique way ids and store the osm id in a tag later.

Did you try if --no-mergeroads helps?
Another option for you special style might be to disable the code that adds arcs for major roads.
Maybe try to comment this line in line 270 in RoadNetwork.java:
addArcsToMajorRoads();

This is improving long distance routing for normal maps but might cause trouble with styles for cycling.

Sorry typo: https://openmtbmap.org/debug_orig_map2.zip will work.

Hi Felix,

tried a few times now but always got "404 Not Found".
Please upload the file to http://files.mkgmap.org.uk/

well finally could access my server again -- maps with the additional patch and debug file here:

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.

Hi Felix,

please try also to compile with this additional patch and produce the debug info again.
The patch simply executes the road merging before the angle fixing. I am not sure
why we don't always do it in this order.

By the way, did you read this post?

Oh thanks - I did not notice that.

Here is now the orig_map compiled with the patched mkgmap. Hope this helps you.
