The above map uses Google Maps. A rough polygon has been superimposed on the map for each of the authorities that has released a dataset. For each authority, I'm using the quickhull algorithm to wrap a convex hull around the points that form the routes of their public rights of way. I'm using some quickhull code that was produced by Jakob Westhoff.
