[Qgis-user] QGIS - Cluster Points alongside lines by a limit

[Nicolas Cadieux]

Hi,

I think geoda should be able to help you with some parts of  this. https://geodacenter.github.io/download.html. This software will cluster points in various group size but will use euclidien distances.

If you are interested in the distances along the network, then the idea would be to build a distance matrix based on the network distances (like an all paires Djikstra) https://www.mdpi.com/2306-5729/5/1/8 and then to use that matrix to create groups based on the n neighbor analysis.  This may take some python programming.
