Hi Clinton,
I have found a reproducible routing error, which occurs when I split and compile the Italy extract from Geofabrik.de.
- The error occurs when routing on the A1 from Modena to Parma. (I have only tested this in MapSource so far.) If I route in the opposite direction (South-East), the problem does not occur.
- As soon the route crosses the tile boundary, the route starts jumping back and forth over a very large area.
Can you route successfully if the roads in question are contained in a single tile? I'm just wondering if it is a general routing issue or specifically an inter-tile routing issue. I only wonder because I have an example map that has broken routing so I know that there still exists problems with intra-tile routing. Cheers, Mark
