[SciPy-User] 2D interpolation question

Hi list,

I'd like to do a 2D interpolation but not sure to use scipy.ndimage.map_coordinates or scipy.interpolate   Your help is greatly appreciated.

I have a large evenly spaced 2D array (say 8000x8000). I need to interpolate over a smaller-but-finer grid (say 500x500). The grid is an evenly spaced rectangular, but it is rotated (i.e., with an angle).

Which scipy function should I call?

Thanks,
Shawn
