I'm planning to write a QGIS plugin which calculates isochrones.

I have created an tested a network in PostgreSQL and now I want to create a plugin. The Idea is to use a point layer as input and calculate isochrones using the network and nodes I've already created

In PostgreSQL I used the pgDrivingDistance function and alphashape for the calculation of the isochrones.

Is there a way of using the pg function in a QGIS Plugin or are there any other Ideas how to implement a function with the same function as pgDrivingDistance?

  • whats your code so far? There are modules from pyqt which allows you to connect to the database and perform queries on it Commented Mar 29, 2018 at 8:40
  • I haven´t started to write any code at the moment. I will take a look at pyqt and keep you updated... thanks Commented Mar 29, 2018 at 8:47
  • You Can also use psycopg2 for that. Commented Mar 29, 2018 at 9:47

There exists already a pgRouting plugin for QGIS: https://github.com/pgRouting/pgRoutingLayer

It has implemented also the driving distance function, but it needs to be upgraded to work with the new QGIS 3. Contributions to this plugin are always welcome!
