The best interpolation method for this is the "Natural Neighbours" technique.

You can also use least squares (There are many variations of this technique)

You can ask the authors of the site I suggested for source code. They also have a paper discribing the technique. You could get this paper and then implement the interpolation technique yourself.

Good luck,

Jeff
