Hello, I am searching for a good idea to convert a raster-flow-direction map into a vector-network map.
Probably I will have to write a script. If it is possible at all... In case of writing a script it mean to me: how to produce a line within r.mapcalc? Has anyone a hint? Cheers, achim PS:for illustration I attached a little picture
