<FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>Beginning sometime in the 1st half of July, we’ve started getting some weird artifacts in surface process models that we’ve been developing using r.flow, r.slop.aspect, and r.mapcalc. The results are linear zones of deposits that seem to follow cell grid lines. This wasn’t happening previous to early July. We’ve scouring our scripts and so far can’t find anything to account for this changed behavior. It acts like some kind of dynamic resolution change artifact, but we are not doing anything to cause this AFAICT.<BR>
<BR>
It is probably something squirrelly in our scripts that we just haven’t seen. But I thought I go for a long shot and ask if there have been any changes that might affect the behavior of r.flow or r.slope.aspect recently. I didn’t see anything obvious in the commit list archives, but may have missed a library change of some kind.<BR>
<BR>
Thanks<BR>
