Dear MathGroup

Somewhere, I have read an article or chapter on a related problem, but I
cannot find the source? Can you help please?

Here is a problem statement:

There is a rectangular plot of land, several acres in size, which is
contaminated by a single hazardous waste. We have some chemical
measurements of the concentation of the waste in the soils at N randomly
spaced points -- these points are NOT on a grid.

From other information about the deposition of the waste, we know that the

        concentration( x, y )

is well behaved and smoothly varying.....

So, I want to use a 2D InterpolationFunction in Mma to model the
concentration in the soils, but first I have to estimate the concentrations
at each of the intersections on a square grid (or a rectangular grid). From
that point, the InterpolationFunction is easy.....

Any suggestions? Thank you for your help
