摘要
面对爆炸式增长的多源异构遥感影像数据和实时快速响应的应用需求,传统的遥感影像生产流程已无法满足影像数据快速检索、高并发访问、行业定制化应用等服务需求。本文基于多源遥感影像管理平台的服务链,提出并建立统一地理信息标准的多源遥感元数据处理方法,通过FTP服务器解决分布式文件共享传输问题,搭建多源遥感影像管理平台,并在平台上尝试以服务为驱动,整合多类需求、服务和数据,构建服务链,实现遥感影像数据的在线实时处理。
Facing explosive growth of multi-source heterogeneous remote sensing image data and the application demand of real-time and rapid response,the traditional production process of remote sensing image cannot meet the requirements of fast retrieval,high concurrent access,industry customized applications,and other service demand of image data.This paper studied the service chain based on multi-source remote sensing image management platform,proposed and established a processing method for multi-source remote sensing metadata based on unified geographic information standard.The problem of distributed file sharing transmission was solved by FTP server,and the multi-source remote sensing image management platform was developed.A service chain was built to realize online real-time processing of remote sensing image data on the platform by integrating multiple requirements,services and data.
