摘要
提出了实时GIS的概念,分析了实时GIS的特征,设计了一种实时GIS体系架构。该体系结构由数据采集层、数据服务层、Web服务层和用户层组成,并对实时GIS关键技术进行描述。用智能手机、RFID等进行实时数据采集,用数据库触发器和消息服务器发布数据更新服务,用服务器推技术实现客户端实时信息接收,用Web内容挖掘技术实现海量网络信息搜索,对实时GIS的应用前景及后期研究内容进行展望。
Proposed the concept of real-time GIS, Analysis the characterized of real-time GIS, designed a real-time GIS architec- ture. The architecture consists of data acquisition layer, data services layer, web services layer and user layer, and description the key technology of real-time GIS. Smart phones, RFID and other real^time data acquisition, release database trigger and news server update services, server push technology to receive real-time client, web content mining technology to achieve mass net- work information search. Finally, outlook the prospects for the real-time application of GIS and post research content.
