[GRASS-user] r.stream : vetor of horton order

[Milton Cezar Ribeiro]

Dear all,

I extracted the drainage and direction from a DEM using r.stream.extract.
r.stream.extract --o elevation=aster_dem_wgs84_UTM threshold=50
   stream_vect=aster_dem_wgs84_UTM_vect_th00050
   stream_rast=aster_dem_wgs84_UTM_rast_th00050
   direction=aster_dem_wgs84_UTM_rast_th00050_direction

How can I obtain a vector of Horton order?!

cheers

milton
