I am trying to generate my own iso-chrones using Google and Python and have reached a point where I can produce two data-sets which I would like to combine in the following way:
What I wanted to do was find a way of combining the points and the roads network shapefile to create a nice polygon that will become the isochrone.
The goal is turn the bottom image (which I create) into something that looks like the native arcGIS drive-time isochrone (the top image) working only with points inside a desired duration and roads shape-file:
