My tried solutions:
- v.clean (snap) to close possible small gaps in the topology
- add length per line segment via field calculator and use this as a 'weight' in v.net modules
- use other v.net modules (e.g., v.allpairs, v.net.path)
I think all modules consider the shortest path from line intersection to line intersection in the general direction to the next node. As a consequence, nodes are connected via short line segments that might not result in the overall shortest path (see 3rd image).
Which module/approach would connect the nodes via the overall shortest path?
