Hi Felix, I think I've found the reason for the problems (increased img size) Your style file probably contains many continue statements. This leads to the following situation: the same OSM way is added multiple times to the road network. For each node of a road, the highway count is increased. For a road that appears twice or more often, that means that all nodes will become routing nodes, not only those nodes that are also used in other streets. In the trunk version, this doesn't happen because each way is only counted once (but also ways that will not be added as roads) It is easy to fix that problem, but I still have no idea why routing breaks with the patch (in the default style we don't add roads multiple times) Attached is the corrected patch. highwayCount_v2.patch <http://gis.19327.n5.nabble.com/file/n5749522/highwayCount_v2.patch> Gerd Felix Hartmann-2 wrote
Smaller?
For me my austria map size increased from 295MB to 345MB...
Routing over long distances is not working at all anymore (much much worse to before). Don't have time (need to sleep) to find out if any roads become unroutable though... On 07.02.2013 22:25, GerdP wrote:
Hi ,
attached is a patch that reduces the img size. Up to now, mkgmap created many so called CoordNodes when a road and e.g. a building shared an OSM node. This is not needed and was not intended. As far as I know it just blows up the size of the img file (typically ~500kb for each tile).
The patch reduces the amount of CoordNodes and also cleans some dead code around the highwayCount.
Please test if you see any (new) routing problems with this patch, I tried quite a while and found none in BaseCamp.
