Inverse distance weighted (IDW)

Spatial interpolation is the process of using points with known values ​​to estimate the values ​​at other unknown points. As we have punctual data we use the interpolation IDW among several methods.

Inverse distance weighted (IDW) interpolation of a set of sample points. The weight is a function of inverse distance. The surface being interpolated should be of a locally dependent variable.

This method assumes that the variable being mapped decreases in influence with distance from its sampled location.
