设计了基于Arc SDE空间数据管理、ArcGIS Server REST地图服务、Flex富客户端可视化查询等关键技术的遥感影像发布系统架构。介绍了系统中显示层、逻辑层、服务层和数据层等结构,利用中间件实现了空间数据库信息到客户端可视化的工作流程。开发实现了遥感影像发布系统,测试结果表明,系统可视化和交互效果好,便于扩展和维护,具有较高的应用价值。

The system architecture of publishing multi-source remote sensing images was designed, based on the key technologies of spatial data management with Arc SDE, REST map services with Arc GIS Server and visual query with Flex rich browser client. The multi-layer framework was analyzed including display layer, logic layer, service layer and data layer. The workflow from spatial database information to client map service visualization was implemented by middle-ware. Finally, a remote sensing images publishing system was developed and implemented with the methods discussed above. The testing results prove that the system can provide better visualization and interaction than traditional systems, easier expansibility and maintenance. And the system has superior practical value.
