I tried again, with a bit more time, and:
* I can compute shortest paths with the two algs
* I cannot get meaningful convex hullsfor the two service area algs.
I'm probably not understanting how the area algs work. Alex, could you
please give a quick explanation, or point to an existing one, and/or
share a sample project and params?
Thanks a lot.
