Abstract：The huge information content of the remote sensing image bring on the great difficulty in the storage.record.transfer and processing for the image. Particularly, when the image processing operate in a micro-computer, the problem is more projecting. Technology of the image compression coding is a main way to resolve the problem. However, a number of the common in methods for image compression coding that are introduced by the literature, most of them bring about the reduction of the information content, a number of them can't suit the remote sensing image, otherwise, the realizing of methods is difficulty. This paper presents the method of adaptive mixed compression coding for image. The method absorbs the advantage for the several means of compression coding. It carry on the compression coding for an image, base on the spatial correlativity and local even level of the image. The method is both to realize easily and has the better effect for the image data compression. Generally, the compression ratio can attain about 2 .0. The method,of adaptive mixed compression coding belongs the redundance compression. It doesn't bring about the information to reduce.
