[GRASS-dev] problem with r.shaded.relief on win7 and vista

Hi all,
I had a problem generating shaded relief (nc dataset, raster: elevation) both on Windows 7 and on Windows Vista, but not on XP, using 6.4.2RC2. Resulting map is scratched with vertical lines. Region was set at 1 meter of resolution. Please could anyone using those platforms verify that? I’d like someone to confirm the defect before opening the bug. Thanks!
Best regards,
madi

tested here on winvista32-box (nc dataset, raster: elevation), g.region
res=1m

I can confirm this.

Yes but the elevation map does not have one meter resolution AFAIK?

You need to use e.g.
g.region align=elevmap
prior to r.shaded.relief to match the elevation map resolution.

yes I know, but it seems to be a different behaviour between winxp and
winVista/win7
(see original mail from Margherita di Leo).
