 在分析卫星海洋遥感单轨三级数据产品特征的基础上,针对游程编码无损压缩算法特征,提出了优化游程编码压缩算法,运用该算法实现了海洋遥感三级数据产品的无损压缩,并与流行的WinRAR压缩软件进行了比较测试,结果表明上述算法对海洋遥感数据均有较高的压缩率,优化游程编码压缩算法在空间复杂度及时间复杂度上均有明显的比较优势,可极大节约海洋遥感数据的存储与共享发布空间。 更多还原

【Abstract】 Based on analysis of the satellite ocean remote sensing L3A data products and the features of RLE(run-length encoding).An optimization algorithm to run-length encoding(ORLE) compression was put forward,which was used for lossless compression to ocean remote sensing L3A data.The lossless compression effectiveness has been tested and compared with WinRAR.The results show that all the algorithms for ocean remote sensing data have a higher compression ratio,ORLE algorithm has advantages in the space... 更多还原
