Onboard data lossless compression of remote sensing image based on "District Forecast"differential coding

DENG Bing①②,LIN Zong-jian②(①School of Remote Sensing and Information Engineering,Wuhan University,Wuhan 430079,China;②Chinese Academy of Surveying and Mapping,Beijing 100039,China)  
A major application of remote sensing image data compression is on-board data compression.According to the statistical rule of remote sensing information content,a kind of differential coding compression method is proposed.When this lossless compression method applied to the multi-spectral data and panchromatic band data tanking from "Beinjing No.1" small satellites,favorable results are obtained.The proposal of "District Forecast" differential coding compression is brought forward.
