开发适合时态 GIS 应用的时空数据模型仍然是一个具有挑战性的研究问题。本文提出了事件和过程的新定义,以描述和建模 GIS 中的时空现象,在此基础上,并基于对象版本的扩展概念,生成了基于事件的概念时空数据模型。
The development of a spatiotemporal data model adapted to temporal GIS applications is still a challenging research issue. The paper presents a new definition of events and processes to describe and model spatiotemporal phenomena within GIS, based on which, and on an extended concept of object version, an event-based conceptual spatiotemporal data model is produced.
