[GRASS-user] Calculate stream order from digitized hydrology network

[Filipe Silva Dias]

Dear all,

I have a digitized hydrological network and I need to calculate the stream
order (Horton, Strahler etc).

I found r.stream.order but it requires that the hydrological network comes
from a DEM, which in my case produced an hydrological network that is
considerably different than the digitized one (tried both with r.wateshed,
r.terraflow and r.stream.extract).

Is there a tool capable of doing this? Apparently ArcGIS can do this, but
id prefer na open source solution.

Thanks

Best regards

Filipe
