Abstract

The three-dimensional spatial description of city construction provides key relationships between the real world and the data model. In the researches of the essential attribute and existence about object, ontology plays an important role in the process of spatial description. It not only provides theoretical foundation for the composition of space entities, but also has a description about spatial relationships of the entities. As an important concept of ontology, Part - Whole itself is a kind of level spatial relationship, and is associated with the nature of the object. In this paper, the description level and the geometry definition of city construction according to the geometry characteristics of entities in space is presented based on the Part - Whole theory of ontology. Then, the relation between each level of three-dimensional spatial entities from two parts of the spatial relationship of ontology (horizontal relation and vertical relation) is analyzed. Next, a framework for describing three-dimensional spatial relationship of city construction based on the ontology is proposed. In the end, a prototype system is designed and realized.
