摘要
现有的空间信息共享平台框架及开发模式较难灵活地完成地理信息服务和应用系统多层次的融合、空间信息资源整合及空间信息的共享等问题。本文通过一种基于SOA网格管理模型(service-oriented architecture,SOA)的空间信息共享平台设计框架,结合空间信息多级网格和SOA服务体系框架的优点解决了在广域网络环境下整合空间信息资源从而有利于空间信息共享的问题,并通过多级地图缓存服务,即利用对各种比例尺的地图数据在计算机内存中的临时存储,来提高用户在编辑、特征渲染和标注等操作的响应速度的技术来解决空间数据的传输和显示等问题。
Existing framework for spatial information sharing platform and a flexible development model is more difficult to complete the application of geographic information services and multi-level integration,spatial information resource integration and sharing of spatial information issues.In this paper,combining with the spatial information multi-grid and the SOA service system framework,the framework of spatial information sharing platform resources that based on SOA（service-oriented architecture） is contribute to the problem of spatial information sharing,which has the advantage of spatial information sharing.Through multi-level map cache service,namely the use of various scale map data in computer memory for temporary storage,to improve the user to edit,feature operations such as rendering and label the response speed of the technology to solve the transmission and display of spatial data and other issues.
