[mkgmap-dev] Testing inter-tile routing with mapsource

I have spent quite a while crawling around a 13 tile map using mapsource and, so far, I can route anywhere that's actually connected. N/S/E/W it doesn't seem to care. Sometimes, it will just draw a straight line but if you break the route down into smaller pieces it can route. It seems like that it's a complexity thing. It just gives up when it thinks the route is too tough to compute (computer says no). Felix's point about the OSM data being not perfectly connected is interesting but we can't control how the gps behaves and we can't just go around linking up roads that look close enough to be connected but aren't actually. So I don't know if we can do much about that. Cheers, Mark
