I will try explain this as best I can.
I have a point on a map and I want to create buffers surrounding the site; for example, 10Km, 20Km 50Km. This is easy. But I also need to show buffers for distance from site, based on road network. lets says 30mins, 60mins 180mins etc.
I have a detailed road network map showing the various road classes, and I could assign average speeds to them but from here...i am lost.
Is this possible in QGIS 2.6.1.
Also if i could use Googles route calculator it would be AMAZING!
Oh and i have tried the route calculator tool, but i want to put in point a, then identify max travel time, then show polygon of area.
