see the man page for an example of making a nicely colored accum map
based on standard deviations.

Why not setting colors for accum in the module?
If you like, but a simple linear color model will not work well:
Hmm, it does work with

so what remains todo befor 6.4rc1? IMO lib API and module list should be
frozen at that point, which means creating releasebranch_6_4. No need to
wait on that anymore IMO. bugfixes can continue on until the end.
if 6.4 is the last, that means for all of GRASS

In r34485 there were a bunch of changes to lib/gis/gisinit.c, one of
which calls G_init_locale(). However, this is not necessarily defined
in locale.c. I'm not really a C guy, but this seemed to fix it for
me. For reference, the build fails on an undefined reference

I am just trying out the new 'r.colors -a'. Results look good, visually
matches 'r.mapcalc abs($MAP)' + 'r.colors -g' exactly.
In general, it won't be an exact match, as -a uses log(abs(x)+1) so
that values close to zero don't hog the colour table. If your range
is small, you

In my personal opinion, flow accumulation of r.watershed is also more
realistic than flow accumulation of r.terraflow (SFD), but I have
admittedly not tested it in detail.
I just wanted to add that I have, in fact, compared the results of the
r.watershed with r.terraflow, as

Since the bulk of the flow accumulation output has little flow, a simple
fixed linear model would work in most cases as it does for the visual
I very much agree with Hamish:
it is really nice to have two independent methods to use race
against
each other, and compare the results of. ie apply the scientific
method.
Each will have its strength and weaknesses and now we can quantify
more
what those are.
I am a big proponent and

Markus Metz:
The new version of r.watershed produces results identical to the
original version at a substantial speed increase by optimizing the A *
search method.
that reminds me, the man page needs updating too,
Both versions use the AT least-cost search algorithm to determine the
