[postgis-users] PostGIS Topology with Z coordinate

[Berchet, Adrien]

I see, thank you very much for these enlightenments.
I think it would be nice to add this support to PostGIS. I think it is
possible to mix PostGIS Topology and PgRouting to get a similar result so
maybe it does not worth it. I will try such a mix when I have some time.
Thanks again,
Regards,
Adrien
