摘　　要：随着国家高分辨率对地观测重大专项的实施,我国计划未来几年研制发射一系列高分辨率对地观测卫星,将大大提高遥感卫星为国民经济和国家安全提供信息保障服务的能力。但落后的影像处理手段导致海量卫星影像快速处理与影像及时应用发生阻塞,不能实现遥感技术价值最大化。利用GXL软件开展了效率对比、生产试验等方面的研究,分析了该软件在海量遥感数据正射影像制作时的优势。With the implementation of major subject of high resolution ground observation in China, the planning of research and development a serious of high resolution earth observation satellite has been coming in the next few years, which can improve ability of security services for national economy and national security provides by remote sensing satellite greatly. But with treatment means of backward, it becomes blocking from rapid processing of massive satellite images to application in time, which cannot realize the value maximization of remote sensing technology. Starting the study of efficiency comparison and production test based on GXL, the advantage in massive remote sensing data production of GXL has been analyzed.
