[GRASS-user] Strange r.slope.aspect output of Aster dem : slope calculations

[manuel.martin]

Hi all,
I just computed the slope using r.slope.aspect on the Aster data over 
the full French territory, and as a result got large artefact stripes on 
a south west-north east axe? When could it come from (inadequate 
re-projection, the slope routine or the aster data)?

The stripped result :

Thank you in advance,                Manuel
