You're right: The routing problems occur even with everything in one tile. I don't know if this is caused by bad data or just general routing weirdness. What would be the best way to analyze this? Cheers. On Thursday, April 9, 2009, Mark Burton <markb@ordern.com> wrote:
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,
