SNoWPAC is a cubic B-Spline wavelet compressor for regular grid datasets (1D,2D,3D). Specializing in lossy compression for scientific data, the goal for this method is to provide a low cost, low overhead compression method for smart data reduction via a series of parameters achieving targetted levels of lossyness.
