s.surf.idw

[Bruce K. Wylie (303) 490 8336]

	I would like some information on the method used to
generate the surface with s.surf.idw. What method was used? Is
it similar to the "moving average" technique (Geo.
Stats.--J.C.Davis)? Does it use the Pythagorean equation? Are
s.surf.idw methods similar to the methods used in r.surf.idw?
What would be a good reference for s.surf.idw?
