[pgrouting-users] Adding bike routes to database

[Daniel Kastl]

Hi Yasir,

Just a question for better understanding:
Are you bike routes user generated (GPS) tracks or are they separate network
data that is just not part of OSM?
If you want to match GPS tracks to an existing road network, there is a
matching.sql with some functions in at least the trunk version of pgRouting.
