随着人类对地观测卫星系统的发展,卫星遥感数据量爆炸性增长。海量的遥感数据对当今存储系统存储容量、数据可用性以及I/O性能等方面提出了越来越高的要求。针对需要持久化存储与高速交换的数据,该文设计并实现了一种基于共享文件系统和文件编目消息推送的海量卫星数据实时存储与交换方法。实验测试表明,该方法针对海量卫星遥感数据的实时存储与交换取得了很好的效果。
With the development of human Earth observation satellite system, the amount of satellite remote sensing data has exploded. Massive remote sensing data sets ever-higher demands on the storage capacity, data availability, and I / O performance of today’s storage systems. For data that needs persistent storage and high-speed exchange, this paper designs and implements a real-time storage and exchange method of massive satellite data based on shared file system and file cataloging message push. Experimental results show that this method has achieved good results in real-time storage and exchange of mass remote sensing data.
