I am looking for a way to produce a time-space map in QGis or ArcGIS. See an example here.
As input data, I have a city in the centre of Germany with travel times to some other cities around it. I am looking for a way to deform the "normal" geographic map of Germany to show the travel time instead of distance.
Any idea on how to do that with QGIS, ArcGIS or other GIS ?
