摘要：A preliminary comparison between loss and lossless compression approaches for the remote sensing data processing was made. A three-stage lossless compression algorithm of multispectral remote sensing images based on wavelet transformations and intra-bands correlation is proposed and developed. It allows one to consider peculiarities of remote sensing data and to increase the compression ratio of the algorithm. The paper describes a modification of the compression algorithm aimed at considerable improvement of com- putational performance and based on bands trimmed enumeration and data selective use. A research of the three-stage algorithm per- formance was carried out in comparison with the universal compression algorithms such as WinRar, WinZip and JPEG2000 using data from various remote sensing systems showing to some extent a superiority in the compression ratio, as well as some insignifi- cant lag of the computational performance was identified
