Hi Garvan,
I have made a cut down sample map showing an error in routing as displayed in mapsource. The source is in polish format, and includes the junction where the errors are found, and a portion of a city to the south. If I delete more roads from the city, the error disappears, even though the error itself is apparently north of the city. The routing works correctly in gpsmapedit.
The graphic file shows the junction where the errors are happening. The route should be west and south from one waypoint to the other, and instead it jumps about, sometimes following roads, sometimes making straight-line jumps.
I can't find the point on the map the graphic is showing. What are the coordinates of the junction between the two flags?
Sorry , the junction is near N13.10330 E100.91647 Garvan
