A few weeks ago I posted a message requesting help with a problem I was having
with r.slope.aspect.  When I used this command on a dem the resulting maps
came out with linear areas of 0 slope in areas that should have contained 
relatively steep slopes.  We'll, I think I found a solution (or at least a
fudge).

I did a reclass of all the areas that had 0 slope and turned them into 
areas of "no data."  I then used r.surf.idw2 to interpolate the values for all
the areas of no data.  The resulting map seems much better than the original
(although it is not perfect).  Does anyone know if I violated any cardinal
rules by doing this?  If so, any other solutions?
