英文摘要：

The management and sharing of multi-source remote sensing images is very important for full using of image data,however,the traditional management modes sometimes appear passive effects in practice,owing to the lack of techniques.In this paper,we presented and discussed the system goals,the system flow,four function modules and four key technologies.Through analyzing the data source,existing management mode and business processes of remote sensing images,we designed a logical organization model of multi-source remote sensing images,and then established a massive remote sensing image database.Then we discussed the four function modules in detail and analysis the four key technologies.The four function modules are image pre-processing,image management,security control and image applications and services.And the key technologies are the system architecture on the basis of plug-in module and messages broadcast mechanism,automatic extracting meta-data,quick searching for images and efficiently online application services.The system uses Client/Server and Browser/Server mixed architecture,which is developed in the local area network to ensure a highly safe reliable and real-time environment.The result shows,comparing with traditional methods,this study achieves a unified and efficient management,quick searching,efficient browsing of massive multi-source remote sensing images and seamless integration with other subsystems,which provides convenient image data services for city application and helps to make further use of remote sensing images.
