public class InverseGridResampler
extends GridResampler

The InverseGridResampler class performs generic data resampling between 2D earth transforms using an inverse location lookup method. The steps are as follows:

1. The destination grid is divided into rectangles of a bounded physical size.
2. For each rectangle in the destination grid, a polynomial function is derived that maps from destination grid coordinates to source grid coordinates.
3. For each coordinate in the destination grid, a source coordinate is computed and data from the source grid transferred to the destination.

WARNING: This class is not thread-safe.
