Is there a way to to something like
ArcGIS provides with the
Network Analyst with open source GIS tools?
What I am exactly looking for is: I am having a roadnetwork and in this roadnetwork I have several points. I want to check if any of these points is further apart from each other than a certain threshold (lets say 1km).
Is there a way to do that with freely available GIS?
I am aware of this https://anitagraser.com/2011/05/13/catchment-areas-with-pgrouting-driving_distance/ But that just gives me the distance of one point.
