摘要:

虽然相对传统的GIS 数据模型而言,人们对时空数据模型的研究起步较晚,但是大量的时空数据模型已经 被提出了。在综述已有时空数据模型时,就如何区别时空数据模型的异同,众多研究人员和学者更多地是比较模型 优缺点或罗列和陈述各模型针对某一案例的实践和应用,而没有阐述模型间的本质区别,没有过多地解释模型扩 展及其关联性,也就无法跟踪已有模型的扩展、变异和发展趋势,最终导致在选择模型的应用、实践和整合其他非- 时空数据模型时,不能做出最优抉择。与众多相关时空数据模型的综述文献不同,本文进一步提升和归纳已有模 型,主要集中叙述众多相关时空数据模型的扩展和关联性,阐述模型间的本质区别,呈现模型的演变过程,从而为 人们在应用和实践时空数据模型时提供科学的指导,为模型的扩展和新模型的研究提供理论依据和参考。

关键词: 关联性, 扩展, 时空数据模型

Abstract:

Comparing to the traditional GIS data models, research on spatiotemporal data modeling, although still in its early stage, has generated a large number of data models. In reviewing these spatiotemporal data models, many researchers focused more on pros and cons or applications of the models, but ignored their inherent differences, expansions and associations; thus losing tracks of their expansions, variations and development trends. This eventually results in non-optimized choices when selecting applications, practices and integration of the model. This paper further enhances and induces the existing models, mainly focusing on 1) describing the expansions and associations of the related spatiotemporal data models, 2) analyzing the inherent differences between models, and 3) presenting the model's evolvement. The results should provide guidelines for the applications of the models and theoretical bases for model expansions and the research of new data models.
