[GRASS-dev] Re: [GRASS GIS] #1577: r.stream.extract/r.stream.order - "calculated" mainchannel vs. "real" mainchannel

[Helmut Kudrnovsky]

what does it means? Any reference? Main channel established in real network
or algorithms of modeling main channel?

the mentionned "real" mainchannel is the part of real Austrian river network
(i.e. listed in the annual Austrian hydrographical handbook as the river
'Isel')

>>an example screenshot of river basin in the eastern part of the alps is
attached

>where it is? 
 
it's in the ticket, see
