@atlefren, just saw your comment. Agree, I'll check with a guy who gave a talk on vitualenv and post back.

comment Install Shapely with GEOS on heroku
I've done some more investigation. With Shapely if you type shapely.geos.geos_version_string you get the version number. I get: "3.3.3-CAPI-1.7.4". So I've located this library at /usr/lib/libgeos-3.3.3.so . Now if I rename it, I can no longer type shapely.geos from python in the virtual environment. So I doubt that it will work on Heroku unless some other action is taken.

comment Install Shapely with GEOS on heroku
On my linux system I find that I have various libraries of GEOS with different version e.g. libgeos-3.2.2.so located in /usr/lib

comment Install Shapely with GEOS on heroku
R.K. Thank you. I've been through that page. As you know my issue is that I don't know how to deal with Shapely's C++ dependency which is I believe called libgeos.so. Does the answer lie in the "Local file-backed distributions" section of your link?

comment Will osm2po or other tools simplify links between nodes?
OK, thanks for a great answer. I follow the reasoning which I had not thought of before. osm2po is a great product to use.

comment Using the PgRouting driving_distance function can we see the edges?
Sorry about the terribly late reply. I left this field for a while. I cannot really remember. I gave up and started using a Dijkstra algorithm directly with the python language. The routine returns the distance (or time cost, if that is how you weight the links/edges) of every visited node back to the source as well as every nodes predecessor node. i.e.code.activestate.com/recipes/…
