Thank you very much, the reason I didn't ask in Pgrouting forum is that I
wanted another way to calculate route, when I downloaded the maps from
cloudmade, the roads wasn't in network shape, so I was thinking how do they
do their route, probably their road network is private.
on another topic, I see that osm2pgrouting works on linux (tested), and I
prefer to work with shp files since I did all the steps before, can you
point me to shp2pgrouting, I know it is possible using ARCGIS it self, but I
heard there is a tool called shp2pgrouting, if you can point me to it, it
would be great.
Sorry I am asking in routing, I should ask this in pgrouting.
Thanks in advance.
