In this paper a compression method for multispectral image data basedon Karhunen-Leove Transformation (KLT) was presented
and the statistical properties of multispectral image using KLT was analyzed. After deducing the theoryof KLT
we discussed the schemes of applying this method to the practical compression system of multispectral image data. A maxium degree decreasing bit flow method is researched and presented. Experiment results shows that this methodcan obtain the compression ratio 3.2~5.3 for sixteen band multispectral
almostlossless. It is superior to the method of applying DCT to remove the spectral correlation .
