[Qgis-user] hub lines

Thu Mar 27 06:10:00 PDT 2025

Good morning.
I have the following question.
I have a number of georeferenced points and I need to generate a route with a road shape and have the optimal route created with all the points at once. There are a lot of points, and extensions from point to layer or layer to point aren't optional for me.

Hi Michael,
I believe what hat you are looking for is Network analysis. You can have a look HERE<https://protect.checkpoint.com/v2/r02/___https:/docs.qgis.org/3.40/en/docs/training_manual/vector_analysis/network_analysis.html___.YzJlOmNvcnJlb3NkZWNvc3RhcmljYXNhOmM6bzpiN2VhNTcyYzdmNmJlZDljYzEzYmM5YzZiMWQyMGFjZjo3OjJlNjM6MDdlMzI2NGMxMTZiZDZlNjRlZjUwY2JmYzQwZDQ0MDgzNWVhOTA5MTgyY2UzMGFmYjE4MzE0ZjQzYjg0N2ZhOTpoOlQ6Tg> which should help. Shortest Path is what you would be looking at.
Kind Regards,

Richard

Subject: [Qgis-user] hub lines

I have produced a map with hub lines using the vector analysis tool but now want to analyse the lines themselves e.g. work out max/min/total distances from a node and not sure how to do this as the attribute table from the hub layer does not have the line related data. Presumably I have to add it to the table but not sure how to do that in this instance.
