基于Condor的遥感数据分布式处理应用研究

Application of Distributed Processing to Remote Sensing Data Based on Condor

遥感系统的不断发展及其应用领域的扩展,致使海量遥感数据快速处理的要求与处理资源不足的矛盾日益突出,利用分布式的处理策略是解决这一矛盾的有效方法。在分析遥感图像数据处理面临问题的基础上,运用Condor建立了实用性的分布式处理软硬件环境,编写了适宜于该环境应用的基本遥感处理的算法模型和任务描述脚本,实现了遥感数据基本处理的分布式操作,最后对分布式环境下的遥感数据处理性能进行了分析。

With the rapid development of remote sensing system and its unceasing expansion of application area, the contradiction between the fast processing requirement of magnanimous remote sensing data and the insufficient processing resources is prominent day by day. The effective method to solve this contradiction is the distributed processing policy. Based on the analysis of the question faced in remote sensing image data processing, the practicable distributed processing software and hardware environment is established by using Condor. The basic processing al- gorithm model of remote sensing data and the duty description script are designed for adapting the environment, re alizing the distributed operation of basic processing for the remote sensing data. At last, the processing performance of remote sensing data under the distributed environment has been analyzed.
