The Delaunay triangulation of the point set is first computed with the z-values of the vertices determining the tilt of the triangles.Interpolation is then simply a matter of identifying the value at each grid node by linearly interpolating within the …

Going On The Grid -- An Intro to Gridding & Spatial Interpolation

Inverse distance weighting (IDW) is a type of deterministic method for multivariate interpolation with a known scattered set of points. The assigned values to unknown points are calculated with a weighted average of the values available at the known points. This method can also be used to create spatial weights matrices in spatial autocorrelation analyses (e.g. Moran's I). The name given to this type of method was motivated by the weighted average applied, since it r… Webdeterministic methods do not use probability theory (e.g. proximal) 5.
