[pgrouting-users] Adding bike routes to database

Hi Yasir,


I have some bike routes data that I would like to insert to the 'ways' table

If you can ensure that you keep a valid topology you don't have to run it
again. But probably it's easier to do so.

You might have a problem if nodes get very close to existing ones. they
might "snap" if you set your "tolerance" value too high.
Also I'm not sure you want to create new roads beside existing ones.
Probably you would like to try to match your bike routes with existing
roads.

Best regards,
Daniel
