Hi Jachym,
Thank you very much for your answer.
I think I was not very clear in explaining my problem. I have to
calculate distance from a line, but the distance has to be calculated
*following a path*, defined by a matrix of direction, as a 'flow
direction' in hydrology. It would be a very useful hydrological tool.
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!
Thank you in advance.
Cheers
