I need to generate routes based on a consecutive set of points exactly as given in this routing script by Anita Graser.
As given in this image, I have a layer of consecutive points as well as a network layer. I need to generate a path along the network using these points.
I tried using her script modifying the lines of code so that it may work in QGIS 3.x
However I get an error indicating that the Network Analysis library couldn't be found.
Is there any method I could use to achieve routing as mentioned here or a way I could edit this script so that it will function in QGIS 3.x?
