I can't find the point on the map the graphic is showing. What are the coordinates of the junction between the two flags? > In another post, I was told there are “short arcs” errors in the polish > format input. Could somebody describe exactly what a short arc is, > (length between nodes, length between routing nodes or something else, > and what is the minimum length arc)? A short arc is where two routing nodes are so close together that they are located at the same point. The minimum distance between routing nodes is approx 2.5 metres. > gpsmapedit reports that all nodes are greater than 5m apart in the input. Good, then it's probably not short arcs that are the issue here.
