[GRASS-user] v.stream.* questions

Hi Rich,

AFAIK, the tool v.stream.order was developed to work with grass vector 
files only (no raster input needed). So, the input needed for 
v.stream.order is the vector lines representing the streams (lines must 
be connected) and points that define the outlet of each river network 
that should be processed. I haven't tested v.stream.order for a while, 
so I am not sure if it still works with newer versions of GRASS?! 
However, tool comes with a testsuite (see source code) and a working 
example based on the NC-dataset to test operability of v.stream.order.
