This question already has an answer here:
I have 2 vector shapefiles (one line, one point), and I have tried at least 4 ways to try to get the distance matrix at one time (and most concern the directions of each river segment)
- quantum navigator
- GRASS tool - v.net.allpairs
- roadgraph plugin
In the end I think that roadgraph plugin is the one which is the closest to my goal, and it also can set the directions of the river, but I can't modify it to get the distances between all pairs of points(and I want to get this in matrix form).
What/How could I do? Is there any other way to get this distance matrix on qgis？
