Hi listers,
I am using GRASS64 on Debian Lenny and I am getting warnings about
ill-conditioned signatures. As usual the sigfiles are created by i.cluster and
I do not know why the first signature is ignored.
I googled the warning but haven't found a solution or workaround for this.
Cheers,
It works fine on my machine. Mac OS X, compilied addon and compilied
GRASS from scratch. The strahler output also looks sensable. I do
have a question, though. Say I have my own delineated streams with
another method, but in raster format- will this still work? And is
there an easy way to a

I inadvertently typed 1 instead of 10 for the resolution of my mapset.
Is there a way to permanently change this setting so that I don't
have to g.region everytime. I want to limit my screwups.

Sorry for crossposting - I do not know whether the problem resides in
grass or in qgis.
I'm following:

All fine, but for the fact that the calculated ndvi map appears on grey
scale, and applying the ndvi color table does not change it.

Hi Andy,
Yes, it looks like the right info for the SPOT sensor platforms.
Iwave.cpp expects the data to be in 2.5nm increments so you will have
to interpolate the data to the correct interval. It's a bit tedious,
but is straight forward. I might be able to dedicate some time to it,
but

Yes, I found this problems too for using v.strahler..
so we tried to solve with r.strahler.. but we still have some problems for
low values of (r.wateshed) threshold..
but maybe Jarek has a better way with this new approach to the problem..
just no dependencies sounds good..
so we wait for good

Hi Jarek!
I think that, with Horton and Strahler, it would be useful also Hack stream
order, it is very nice because assigns value 1 to the main channel and so it is
simple to achieve the main channel lenght. (Please see
