Dear all,<br><br>I have a digitized hydrological network and I need to calculate the stream order (Horton, Strahler etc). <br><br>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).<br>
<br>Is there a tool capable of doing this? Apparently ArcGIS can do this, but id prefer na open source solution.<br><br>Thanks<br><br>Best regards<br><br>Filipe<br>
