Hi Mark, I've experienced the same problem: a short arc disappered in Rome (I'm still looking for it...). And the routing gets broken. Did you understand why those short arcs (with no collapsing end nodes) get deleted? Ciao, Marco. --- Gio 4/6/09, Mark Burton <markb@ordern.com> ha scritto:

Hi Felix,
Shame on me, I had in my batch the call for the unpatched mkgmap version, which of course did not.
OK.
What can I say about the patch? Get it into TRUNK!!!!
I will commit it soon as it won't affect the default operation.
Finally Routing over longer distances IS possible. Route calculation time decreased in mapsource by up to 50%, and possible route length increased about 20-25%. Also no single Mapsource Crash since!!!!!!!!!!!!!
Good.
At least in Austria where because of the import, many roads are not connected, this patch is absolutely essential!
The patch only merges nodes that are close and already connected. It doesn't merge nodes that are close and not connected.
On my Vista HCx also many destinations that previously took 2-3 minutes to calculate just calculated only 20-30 seconds!
Great.
Maybe don't enable it by default, I have not really tested whether now there are any problems with roads connected that should not be connected, but so far it has been working great!
I will commit something that has the same effect as the patch you have tried.
Cheers,
Mark _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
