I'm just starting to read the tutorial for pgRouting and the first issue that troubles me is the origin of the "base map" to feed pgRouting with. I'm aware that there's available a tool called osm2pgrouting, which converts OpenStreetMaps data into pgRouting compatible ones. But I'm not sure if it is the correct/best source for this info, although it clearly might be a starting point and is fairly easy to get it.
What are the other possible source options for this purpose?
I work in an AVL company so, we gather second by second lots of GPS data from vehicles, which we don't actually process to "connect the dots" and turn them into streets, but I'm not sure if this actually helps or not.
Data needed for this project would be for Chile and, as starting point only for the city of Santiago.
