I have created a network with the GRASS module v.net. But when I try to create the travelling salesman path with v.net.salesman, I get:
Destination node 9383 is unreachable from node 9398
If I put the topo lines or points from the network into QGIS I can find the two nodes, but I can't manually figure out why one is unreachable from the other. The Topology Checker shows no errors. I know that the v.net.salesman works because I was able to create the path with another dataset. This dataset is faulty, even though v.net created a network. Is there a tool either in GRASS or QGIS that I can use to fix this problem?
