空间信息应用集成与互操作

Integration and interoperation of spatial information applications

基于WebServices技术和GML(geographymarkuplanguage)技术,给出了一个新的空间信息应用集成与互操作系统——π系统框架(PKUapplicationsintegrationsystemframework),将不同的空间信息获取服务和其他空间信息查询分析服务有机地集成起来,屏蔽了空间信息应用的分布性和GIS平台的异构性.对于π系统框架的使用者来说,如同在网络中使用同一GIS平台开发一样,能够使用不同GIS厂商平台的空间分析服务,也能使用不同空间信息库进行空间信息的存储和查询.

Based on Web Services and GML Techniques, a new integration and interoperation framework - π System framework (PKU applications integration system framework) is presented. π System framework can integrate different spatial information access services and other spatial query or analysis services automatically to complete GIS tasks, and shield the distribution of spatial information and the heterogeneity of different GIS platforms. Further developers can use π system as the same GIS platform in network: they can not only use spatial analysis services from different GIS venders, but also store and query different spatial databases.
