Thanks, Stuart, but that doesn't appear to be the problem.<br>

I have had banding issues like that with r.shaded.relief when the
resolution of the computational region is set higher than the
resolution of the input elevation data. You can set this with
'g.region res='.<br>

Hello all,<br>
Are there known issues with "banding" in the output of the
r.shaded.relief command? When I say banding, I mean the
generation of regularly occurring, narrow vertical and
horizontal lines. I've just created a large shaded relief map
of the northern Pacific coasts of the USA and Canada from the
STRM 90m v.4 Arc/Ascii files. At ~380 m intervals, ~30 m bands
have been generated that crisscross the output. I'd like to
know if this is a consequence of the STRM 90 data set (notably
3DEM appears to have no similar trouble with the same data),
or an artifact of the shaded relief command in GRASS. I can
attach an image if this would help the diagnosis.<br>
<br>
Much appreciated,<br>
