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 :

Could these stripes be related to the ASTER satellite's path ?
See the map of Terra paths here:
