Im a novice user.

Im trying to perform spline and IDW interpolations from 12 points to produce an elevation model of groundwater levels, but ArcGIS spits back an error and says that I don't have enough points.

What is the minimum amount of sample points needed for spatial analysis interpolation?

Is there a way I can produce a set of DEM's from 12 sample points?
