I am using SRTM dem (dem raster) projected in UTM, for delineation of streams (Canales) in my area. I used these grass gis extensions:

r.stream.extract --overwrite --verbose \
      elevation=dem  \
      threshold=1000   \
      stream_raster=Canales  \
      stream_vector=CanalesV   \
      direction=Direccion

r.stream.order stream_rast=Canales  \
     direction=Direccion  \
     strahler=strahler  \
     shreve=shreeve  \
     horton=horton   \
     topo=topo   \
     hack=hack 

Now I need to see in the vector attribute table, for every single channel CanalesV its order already obtained in horton and other rasters too.

How can it be done in Grass GIS?

Your r.stream.order command should have the parameter stream_vect=CanalesV, instead of in the r.stream.extract.

  • that is right! I added stream_vect=CanalesV to my code for r.stream.order and I have everything! Thank you! – Juan López Jan 19 '17 at 16:03
