基于UML的时空建模

现实世界中存在大量的时空数据，时空数据的管理对时空建模提出了更高的要求，因此成为当前许多领域的研究热点.UML作为众多领域广泛使用的统一建模语言，基于UML的时空扩展模型也成为许多领域时空建模的重要形式.为此，本文提出一种时空UML模型，该模型能够表示与处理时空对象的多种时空拓扑关系(包括RCC-8空间和Allen-13时态拓扑关系)以及它们之间的复杂语义关系(例如关联、聚合、泛化和依赖)；同时给出了时空UML的形式化表示形式和语义解释方法.最后结合地籍变更的实例说明了所提方法的可行性和实用性.

Spatio-Temporal Model Based on UML

There are a lot of spatio-temporal data in the real world. The management of spatio-temporal data has proposed higher requirements for spatio-temporal modeling， which has become a hotspot in many fields. UML is a widely used unified modeling language， and the spatio-temporal extension model based on UML has become an important spatio-temporal modeling approach of many fields. This paper presents a spatio-temporal UML model， which can deal with a variety of spatio-temporal topology relationships (including RCC-8 spatial topology and Allen-13 temporal topology relationships) and the complex semantic relations among the spatio-temporal objects. In addition， this paper provides a formal definition and semantic interpretation of spatio-temporal UML model. Finally， an example of cadastral change is provided to demonstrate the feasibility and practicability of the proposed model.
