基于 UML 的时空建模.

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. [ABSTRACT FROM AUTHOR]
