研究地震数据存储及交换的SEED和miniSEED格式标准,对存储格式中的Steim1和Steim2的压缩方法和编码方式进行了深入分析,对比了国内外SEED格式的差异,利用MATLAB软件实现了SEED和miniSEED格式压缩数据的解压和应用。
- Abstract:
-
In this paper,the SEED and miniSEED format standards for seismic data storage and exchange are studied. The compression methods and coding methods of Steim1 and Steim2 in the storage format are deeply analyzed,and the differences between SEED formats at domestic and abroad are compared. Decompression and application of compressed data in SEED and miniSEED format are carried out based on the MATLAB software.
