[OSM-dev] Building routable graph from OSM data

[Mateusz Konieczny]

"The question is what the final purpose is."

Custom routing (more complicated than just finding route from A to B).

"For smaller scale graph stuff i am using postgis with the osmosis schema"

Can you give example how it is done (code/documentation)?

"not on a per country size."

For start it would be city-sized data, I am not interested in processing
data for
entire planet. It would be anyway routing for bicycle/pedestrians so range
is
limited.
