Electric network is a kind of utility network in GIS. In this network we have a point layer that consist power stations and end users. Power stations called source and end users called sink. And also we have one or more line layer that consist power lines. (in the simplest case).
The direction of this network is from sources to sinks
My question is how to use pgRouting to identify the direct of this network? pgRouting has function called pgr_createTopology that builds a network topology based on the geometry information. When I call this function it fill source column and target column of my line layer. source and target show the direction of my network. But this direction is not based of source and sink.
In general can we define our own direction in specific network with pgRouting and not use its default direction?
