3

I am looking to calculate the shortest distance along a road network for multiple starting points. The reason I am not doing this manually is that I have more than 5000 starting points. Does anyone know how to do this in QGIS 3? I have researched extensively with no results for this particular problem.

Input data: Input data part 1 Input data part 2

Snapshot of the results, which are probably wrong: Results snapshot

If only distance is the desired output of your analysis, you may use the QNEAT3 plugin as mentioned in this answer. You can use the OD-Matrix algorithms to compute the distances/duration between points of one dataset or two different point datasets. You can install the plugin via the plugin manager in QGIS.

  • @Oliver, are you looking at just obtaining the distance of each point to the road network?

  • Hi Tim. Yes I am. I am planning on exporting the distances to excel afterwards an continue my work there, so unless that it not an option, just finding the distances is enough for me. :)

  • @Oliver did you manage to achieve the desired result with QNEAT3?

  • @root676 Sorry for late answer. No, I have tried but I am still not sure what to use for the network layer. Also, does qneat3 calculate routes for the many points or does it simply calculate distance (direct distance in a line)?

    @root676 I wasnt able to find a mail in the link, but after a little digging I found a gmail with your name in it to which I have sent the files. I hope it is the right one, but I do not want to show it here in case you would like it to be private.
