[Qgis-user] Developing a directed graph
Hello everyone, I am looking to create a directed graph based on a set of sensors on a road network. I have the coordinates of the sensors and the shape file of the network/ road layer. Is it possible to develop a directed graph / adjacency matrix using GIS tools. I have little to no experience in python scripting and hence looking for some inbuilt tools in GIS.

Re: [Qgis-user] Distance matrix using shortest path
Hi, The QNEAT3 tool for 'OD Matrix from Points as Table' works perfectly well for the problem. However, the API has limited access to points. I have a set of 1400 points, whereas the API allows only 50 points for matrix development. Is it possible to increase the access points?

[Qgis-user] Distance matrix using shortest path
Hi guys, I have a shape file with set of points on a road network. I am trying to find the shortest distance among these points using the shortest path tool. I have tried using the distance matrix tool in QGIS but it gives eucledian distance between these points whereas I am looking the path distance (based on road network). Can someone please suggest some tool or technique that can help me solve this problem?

[Qgis-user] Map matching in Qgis to plot trajectories
Hey guys, I am looking to plot the paths for different vehicles in qgis using the co-ordinates but cannot find a solution to it. I tried plotting using point to path processor but the points connect linearly whereas I am looking to plot the path that are realistic (similar to what we observe in google maps). I am using OSM as the network layer for projection. I also tried the plugin tool "offline map matching" but that didn't help. Can anyone please help me with the problem?
