Hi Andrzej, what do you mean with "break continuity of roads" ? My understanding is that such a relation is only used at nodes where mkgmap will create a so-called route node.

I can only suggest for mkgmap to break continuity of roads at junction indicated by "through_route". This could give more warnings from navigation. I'm not sure how popular "through_route" is. If there are redundant cases, break could be limited for roads type 0x01-0x03 and when "through_route" turns with acute angle. Too many breaks would degrade routing performance. -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
