Spatial Interpolation Techniques
Spatial interpolation methods are important techniques for computation of
spatial data at unsampled locations from sample data available in the domain.
A number of methods have been developed for spatial interpolation in various
disciplines and there are a number of different terms used to distinguish them,
such as ‘interpolating’ and ‘non-interpolating’ methods or ‘interpolators’ and
‘non-interpolators’. In this chapter, all these methods are referred to as spatial
interpolation methods or spatial interpolators. Many of these methods have
modified versions suitable to compute different variants of spatial data. The
