WebNatural neighbours are a concept from the field of Computational Geometrywhich describe properties of arbitrarily distributed points in any number of dimensions. They have … Natural neighbor interpolation is a method of spatial interpolation, developed by Robin Sibson. The method is based on Voronoi tessellation of a discrete set of spatial points. This has advantages over simpler methods of interpolation, such as nearest-neighbor interpolation, in that it provides a smoother approximation to the underlying "true" function.
