Spatial interpolation is the process of taking measurement information from a set of points and extending or interpolating that measurement across a spatial region. The key idea is that measurements ...

Interpolation includes the set of mathematical and statistical procedures applied to derive estimates at unsampled locations within the spatial coverage of the sample values available. Interpolation ...

With inverse distance weighting we interpolated to new, unobserved locations by using a weighted average of the values at sampled locations, with the weights inversely proportional to the distance to ...
