[GRASSLIST:4506] filter out extrem values

Hi!

I got 35000 points where I measured the depths of a lake. Now I have to
filter out the extrem values (maybe by moving average?). 

I want to interpolate the surface of the lake bottom.


I'm not quite shure if s.windavg is what I'm looking for or shall I
switch over to gstat? 

Thanks
Malte
