| 摘 要： | 提出主动空间信息服务的概念,主动空间信息服务是网络条件下解决空间信息服务不同节点及其服务对象的分布性和空间信息服务的实时性要求之间的矛盾而提出的。为满足主动空间信息服务的需求,提出主动式地理信息系统的概念,并就主动式地理信息系统的体系结构、实现途径和关键技术进行了研究。实验结果表明,主动式地理信息系统可以有效地提供实时空间信息服务。

| Abstract: | Spatial information service has the demand of real time.The active spatial information service is the need to overcome the illogicality between the distributed feature and the demand of real time of the spatial information service.Firstly,to resolve this illogicality,this paper advanced the conceptions and active geographic information system.Secondly,it advanced the architecture and active service rules of the active geographic information system take example for a node of the distributed GIS.Thirdly,it considered that a node of the active GIS includes a typical GIS,an event drive knowledge base and an event monitor.The realization of the active function depended on the event monitor scout some event's arise and active service rulers in the event ruler base.Lastly,it advanced basic event and its expression,event operation's methods and the expression of complex event.And studied the realization approaches and key technologies of the active geographic information system.The architecture,realization approaches and key technologies had been tried in a application GIS.The experiments indicated that the active geographic information system is efficient for real time of the spatial information service in the distributed environment. |
