Hi Markus,

Cheers

Hi List!
I was wondering if there is a way to obtain a (raster) map of distances from
a point or a line, in which the path is defined by a map (i.e. a flow
direction).
It would be very useful for me!
if I understand what you mean, r.cost should do it:

-> Example Distance to water (r.cost)
The r.cost manual page contains an example.
