andsat Thematic Mapper (TM) multispectral imagery, while reducing image information loss. The method first removes interband correldtion of the image data by use of the Karhnnen-Loeve transform to prc luce the image principal components over the seven Landsat bands. The prin- cipal components are then compressed using wavelet and lossless en- coding techniques. Image compressions of typically of
