05 Feb 2013 Surface Fitting using gridfit Model 2-d surfaces from scattered data Author: John D'Errico

This is an amazing program. I do have one question. I have a scattered grid of latitude(Y) and longitude(X) coordinates corresponding to brightness(Z) values. I've been using GRIDDATA to interpolate to a new grid that is not scattered and within a smaller range of latitude and longitude values, but GRIDDATA smooths the data so much that it becomes useless.

I understand that GRIDFIT is not an interpolant, and from my reading of the help, it does not seem that it was meant to be used in this fashion, but I just want to make sure.
