I am looking for an open source GIS and now asking myself if it is possible to integrate a route planner into QGIS.
The route planner should be able to calculate the distance from one position in the map in all directions (e.g. 30 minutes driving time) and mark it as a catchment area. It would also be helpful to export the data of the marked area to excel (e.g. name of the administrative districts and also demographic date).
