多源多波束数据格式解码及统一管理软件设计

Multi-source multi-beam data format decoding and unified management software designing

多波束数据的广泛利用目前存在两个问题:一是多波束数据多以二进制等形式存储,难以直接进行读取使用;二是由于不同厂商的数据格式不同,批量处理多个来源数据的难度较大。为此,研究了S7K、ALL、HSX、XTF、XSE、GSF共6种主流多波束数据格式及数据结构,并比较分析了不同数据格式之间的差异性。在此基础上,设计开发了一款能够自动解译并快速显示和存储所需数据的软件系统。该软件通过数据库技术管理海量数据,可以按照自定义格式存储关键数据并以文本格式输出,数据可视化图形实时检索定位,有助于提高多波束数据解译和分析的效率。

The widespread utilization of multi-beam data currently has two problems:first,multi-beam data are mainly stored in binary format which is difficult to read and use directly;second,the formats of data vary greatly among different manufactures so that the data from different sources cannot be batch processed.Therefore,this paper not only studies the data formats and the data structures of six mainstream multi-beam,such as S7K,ALL,HSX,XTF,XSE,GSF,etc.,but also compares and analyzes the differences between different data formats.Based on this,a software system that can automatically decode with quickly display and store the required data is designed and developed.The software manages massive data through database technology,which can store key data in a customized format and output it in text format.The data can be visualized for real-time retrieval and positioning,which helps to improve the efficiency of multi-beam data interpretation and analysis.
