A method of spatial interpolation from an arbitrary arrangement of numerical observations is derived, with examples shown as contour maps. The fit to the original data and the smoothness of the resulting lattice values are optimized simultaneously by an iterative numerical technique. The algorithm does not require specification of distance dependent influence functions.
