Hi Marko,
In the warning output of finland.osm, I see 219 warnings about turn restriction relations. Apparently, there not that many errors in the map data, because I see duplicates, like this:
2009/10/20 15:39:32 WARNING (RestrictionRelation): Turn restriction 167929 has multiple 'to' members - first 'to' member is 18628061 2009/10/20 15:39:32 WARNING (RestrictionRelation): Turn restriction 167929 has multiple 'to' members - first 'to' member is 18628061 ... 2009/10/20 15:39:32 WARNING (RestrictionRelation): Turn restriction 167929 'to' way (18628061) doesn't start or end at 'via' node (62,59660/23,66127) ... 2009/10/20 15:40:11 WARNING (RestrictionRelation): Turn restriction 167929 has multiple 'to' members - first 'to' member is 18628061 2009/10/20 15:40:11 WARNING (RestrictionRelation): Turn restriction 167929 has multiple 'to' members - first 'to' member is 18628061 ... 2009/10/20 15:40:11 WARNING (RestrictionRelation): Turn restriction 167929 'to' way (18628061) doesn't start or end at 'via' node (62,59660/23,66127)
Could I get the two sets of warnings because I am running with --max-jobs=2? Would it be possible to suppress the duplicate warnings, or at least display a download URL for each violation, e.g., for the 'via' node?
Yes, those warnings are not ideal - I will take a look and see if I can remove the dups. Also, I nearly added the download URL the other day but I was too lazy, I'll do it now!
All in all, there do not seem to be too many errors in roundabouts and turn restrictions in Finland. I should be able to fix them myself, eventually.
I did not enable the checks on flare roads yet. In many roundabouts, the flare roads are bidirectional "radial spokes" instead of triangle-shaped oneway streets. Are these converted by mkgmap automatically? If not, could they be?
The thing about automatically converting stuff is that you have to be 100% sure that it's wrong otherwise you just make the problem worse. I guess the triangle shaped flares could be fixed automatically but when I go and edit the OSM data where the flare road errors are, I am finding all sorts of bad stuff and fixing that as well so it has a double benefit.
