[pgrouting-users] Can pgRouting assign source and target id that follows the same direction?

[Heinz Chen]

Hello, guys, I am working with PostgreSQL 9.2 and pgRouting 2.0 to route my
river network. My question is hard to give it a brief title, so I post some
details in the forum,

pgRouting assign number of source and
target<http://stackoverflow.com/questions/23887283/pgrouting-assign-number-of-source-and-target>

Can I achieve my goal? Or is there any other way to solve this problem?
Please give me some hint to begin with and feel free to give me any
suggestion, thanks!
