Hi List, I've been using v.net.allpairs [1] for the calculation of shortest paths between pairs of nodes on a river network, and it is working very well. However, for some datasets there are several thousand individual nodes and I would like to reduce the associated processing time if possible.
Based on the documentation and the current outputs, the module calculates the shortest paths between all pairs of nodes on the network. In my case, I'm only interested in the shortest paths from one specific node. I'm therefore, wondering if it is possible to use the module in this way and limit the shortest path calculations from one node to all of the other nodes on network. I tried to use the 'cats' and 'where' options, but so far to no avail. I appreciate I am overlooking something, but would value any feedback or advice on how to reduce the associated processing time. Thanks in advance. Regards Daniel.
