为了满足对运动目标和传感器的实时观测数据的采集、存储、分析和可视化的需求，需要发展一种新型的GIS--实时GIS。根据各种地理要素的特点和实时GIS中存储管理的要求，提出了一种面向动态地理对象和动态过程模拟的实时GIS时空数据模型，该模型集成了时空过程、地理对象、事件、事件类型和状态等相关元素，并在此基础上开发了一个新的GIS系统，实现了四个动态地理对象的时空数据实时访问、存储和可视化（运动对象、现场对象、视频对象和过程仿真对象）为例，验证了模型的可行性。
In order to satisfy the requirement of real-time observation data acquisition,storage,analysis and visualization for moving object and sensor,a new type of GIS,real-time GIS,is needed to develop.A real-time GIS spatiotemporal data model is proposed for dynamic geographic object and dynamic process simulation according to the characteristics of various geographic features and the requirements of storage management in Real-time GIS,the model integrates some related elements-spatiotemporal process,geo-object,event,event type and state.A new GIS has been developed based on the spatiotemporal data model,and this paper takes spatiotemporal data real-time access,storage and visualization of four dynamic geographic objects(moving object,situ object,video object and process simulation object)as an example and verifies the feasibility of the model.
