摘要:Current research on spatial temporal data modelling meets many problems, such as the separation of space and time, application- driven, not incorporating human cognition and confusing of representation for discrete and continuous spatial change. This paper proposes a general object-oriented model that tries to overcome above problems. The model is directed by human cognition on spatial object that each object have what/where/when attributes. Attributes of theme, space, and time are tightly linked to each other in a unified object class. The precise and flexible structure of this model supports multi-semantics of space and time. Besides complex spatial relationships, it is also capable of modelling linear/branch/cyclic time order, various spatial change, and complex temporal relationships. Verified by different spatial temporal scenarios, this model is proven to be extendable to different spatial temporal applications
