Hi.

I was trying to get an estimation from v.report on the total length of
drainage network (so as to compute drainage density, D=\sum(L)/A) but I
got stuck as I'm not able to get v.report to understand that I've set a
mask on a certain watershed and so he should compute me only the length
of the drainage network corresponding to the mask that I've set.
Is v.report ignoring my musk? Can't I get a way of computing the
drainage density for each watershed?

Thanks
