[postgis-users] flow analysis

[Jonatan Malaver]

The WITH RECURSIVE construct looks a lot as to what I am trying to do. I'm not sure if pgRouting has functions already built in.

Thanks,

Jonatan Malaver

Hi,

Here is a write up of a Max Flow Analysis I found on the pgRouting wiki:

https://github.com/pgRouting/pgrouting/wiki/Max-Flow

But I am not aware that this was ever implemented. I also searched to see if Jay had it in fork but did not see one.

I'm CC'ing this to the pgRouting list as someone might have more information on this.
