多源空间数据汇交服务系统的应用研究
|
摘要
多源空间数据汇交服务是以兼容性的空间数据存储模型为基础,采用自动化的网络传输方式完成异地空间数据源的交互,是空间数据共享理论的一种具体实现。汇交服务能够有效地提高政务系统内部空间数据传输共享的执行效率,缩短地方政府地理信息综合应用平台的建设周期。本文首先介绍了空间数据汇交服务系统的总体架构和运行模式,然后通过多项测试验证系统的执行效率和稳定性,并验证其实际应用价值。
Multi-Source Spatial Data Exchange Service is based on the compatibility of space-based data storage model,and adopts automatic transmission via Internet for spatial data long-distance communication. It is a specific realization of the spatial data sharing theory. Exchange service can effectively improve the efficiency of spatial data's interflow in different government department,and shorten the construction period for local government geographic information integrated application platform. Firstly,the overall architecture and running mode of the Spatial Data Exchange System is introduced,and then execution efficiency,stability and practical application value of the system has been verified by a list of system testing.
