[Numpy-Discussion] 3d interpolation

[Robert.Denham at dnr.qld.gov.au]

I have a series of x,y,z irregular data points.  I would like to create a
2-d array (surface) from this data, each cell in the array being an
interpolated value based on the nearby z values.  I was wondering if anyone
had any experience or suggestions under python?  The interpolation algorithm
needn't be elaborate, kriging is definite overkill, I was thinking more
along the lines of splines or even inverse distance weighting.

Thanks
