[pgrouting-users] about use of navteq data

[Daniel Kastl]

Hello Emre,

I'm not sure exactly about the ID's of Navteq data. It's too long ago that I
have used it.
But it's better to have ID's starting with 1 and to keep them low. This
might be the reason why it's slow.

So you could create two new columns and renumber ID's. You don't have to run
topology function.

Daniel
