positions in python?

I have a very simple problem which I am not able to solve with my
current knowledge of scipy/python/...
I have a set of positions X, Y, and intensities Z provided in 1D arrays.
The positions are NOT at all on a regular grid.
Now for a new position Xnew, Ynew I would like to get the *interpolated*
Znew value, and if possible trying different schemes such as "bilinear",
"cubic", etc... I also would like to know if my point is EXTRApolated or
not so I can decide what to do (either take the extrapolated value or
Any suggestion on this simple item?
Thanks in advance
