====== Inverse Distance Weighted ======

Inverse Distance Weighted (IDW) interpolation is simple and easy to use. It only takes an exponent as parameter. The resulting grid always intersects the data points. In 2D a low exponent produces rounded spikes, whereas higher exponents produce steep spikes.

A detailed description of the algorithm is beyond the scope of this documentation\\
