【摘要】 为解决地震数据的无损压缩存储问题,研究了多种地震数据标准以及整型和浮点型数据的无损压缩算法。在此基础上,提出了地震数据的无损压缩存储方法。该方法通过分析多种地震标准的内部结构特点,有针对性地对整型和浮点型数据分别进行无损压缩。在保证了地震数据文件中各参数、标识等信息不被破坏的条件下,最大限度地减小了地震数据文件的大小。试验证明,本方法不仅对整型数据而且对于浮点型数据都可以做到无损的数据压缩与还原。更多还原

【Abstract】 To solve the problem of seismic data lossless compression effectively,many seismic data standards,lossless integer and float-point encoding are studied.Based on these,a design method of lossless compression of seismic data is presented.By analyzing the structure of the seismic standards,the integer data or float-point data is compressed separately in the method.The messages of seismic files are saved and the volume of the files is decreased as possible in the method.Finally,the feasibility of the method is validated by practical application.更多还原
