[Qgis-user] Shortest path (Network Analysis)

[Nicolas Cadieux]

Hi,

Is there an all-paires options?  If so, you can put the source and destination in the same file and all possible source and destinations will be done.  You will then need to filter of what you don’t need.  How many routes are you dealing with?

I may have something for you but it’s not published OpenSource yet.  Could be useful if you have millions of routes to calculate.

There are two plugins (Networks and QNEAT3) and Network analysis tools in Processing Toolbox but none of them allow me to calculate shortest path between two layers. Either the tools will allow me to find the shortest route between a layer (multiple locations) to a single location by picking interactively an origin or a destination location or interactively picking one an origin and a destination location. However, none of the tools will allow a person to upload or select two layers that has multiple point locations to calculate the shortest path.
