[GraphHopper] Using Shapefile as primary data for routing

[Rodolphe Quiédeville]

Hi,

What about using shp2osm http://wiki.openstreetmap.org/wiki/Shp2osm to
do this ? As the result will be an .osm file it will be easy to
transform it after to a .pbf file with
http://wiki.openstreetmap.org/wiki/Osmconvert and use it directly with
GraphHopper.

No programming will be necessary but some shell scripting anyway, I'm
afraid there is no solution out of the box.

Regards
