摘　　要：通过统一多源异构遥感影像元数据建库标准,解决多源遥感影像数据信息异构。将元数据库与瓦片分级管理机制相结合,即时融合多源多时相遥感影像数据,有效解决多源遥感影像数据组织方式和版本异构问题。运用GIS、Web等技术搭建遥感影像即时服务云平台,实现多源异构影像数据高效查询检索、统筹管理与即时服务,提高影像数据共享与应用效率。In order to solve the heterogeneity of multi-source remote sensing image data,this paper unifies the standard of multi-source heterogeneous remote sensing image metadata database construction.The metadata database and tile hierarchical management mechanism are combined to fuse multi-source and multi-temporal remote sensing image data in real time.Thus,the problem of heterogeneous organization and versions of multi-source remote sensing image data is effectively solved.GIS,Web and other technologies have been used to build a cloud platform for real-time service of remote sensing images,to realize efficient query and retrieval,manage the immediate service requirement,and improve the efficiency of image data sharing and application.
