[GRASSLIST:7591] Network accumulated values

[Iñigo Marin]

Hi all,
 
I'm interested about getting accumulated node cost values(attribute of
the node) through the different paths from the outlet point of a
dendritic, arborescent network to the multiple ends of it.
 
 
This could be interesting for many purposes like getting the total
population or area served by a drainage network, ...
 
Maybe this could be done with some scripting using d.path...
 
 
Any ideas??
 
 
Thanks
