Abstract: We investigate the possibility of using of hierarchical storage compression for problem of hyperspectral images storage. Results of image analysis of SpecTIR and AVIRIS spectrometers shown. Approximation of the spectral channels is proposed to improve the efficiency of the method while still allowing access to individual components. Computational experiments to study the efficiency of the developed algorithms on 16-bit hyperspectral images implemented.

Keywords: image compression, hyperspectral images storage, control of maximum deviation, hierarchical grid interpolation.
