摘要
根据地理本体思想,提出和构建了基于对象-事件-过程的面向对象的时空数据模型。该模型基于3个基本地理实体类型:地理对象、地理事件和地理过程,三者基于地理本体的特性,本体化地表达和概括了地理现象和事物。该模型能有效地描述和表达复杂的地理动态现象和事物,能增强性的探讨和表征地理现象发生和发展的内在关联。甚者,鉴于描述和表达三者的侧重点不同,该模型可灵动性地整合或拆分成其它时空数据模型,不失为一种通用的时空数据模型。最后,以动态变化的海冰为例,验证了模型的可行性和有效性。
Based on the characteristics of the ontology, this paper discussed the construction of a modeling approach for dynamic geospatial domains based on the concepts of geo-objects, geo-events and geo-processes, which is called OEP （Object-Event- Process）-based spatiotemporal data model. The OEP-based model can effectively describe and represent the complex dynamic geographical phenomena. This model can also enhance the exploration and characterization of geographical phenomena associated with the occurrence and development of internal evolution. More importantly, given the different emphases on the geo-objects, geo-event and geo-processes,the model can integrate or be split into other spatiotemporal data models, so that it can be assumed as a unified spatiotemporal data model. Finally, this model can be applied to model the sea-ice dynamics, and validate itself feasi- bility and effectiveness.
