Resampling Filter


Description

Resampling filter for grids. Resamples in a first step the given grid to desired resampling cell size, expressed as multiple of the original cell size (scale factor). This is an up-scaling through which cell values are aggregated as cell area weighted means. Second step is the down-scaling to original cell size using spline interpolation. Specially for larger search distances this is a comparably fast alternative for simple low and high pass filter operations.
