I still achieve best results by simply setting max nodes to 250 (which I assume of being quite save, yet sufficient). As testmaps with streets longer than 260 points (using max 300) caused no probs, I am pretty sure problem lies somewhere else > Cheers, > > Mark > _______________________________________________ > mkgmap-dev mailing list > mkgmap-dev at lists.mkgmap.org.uk > http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev > -------------- next part -------------- An HTML attachment was scrubbed...
