| 摘 要： | 本文结合三维地籍空间实体的特征,依据现代地籍管理需求,对OO3D数据模型进行扩展,提出了面向地籍的三维数据模型(CO3D),并详细阐述了CO3D的逻辑和概念模型,研究了CO3D拓扑关系类型、存储结构、查询方式的实现方法,探讨了模型的可视化原理及实现,并通过实例验证了CO3D模型的正确性和可行性。

| Abstract: | According to the characteristics of spatial entity in 3D cadastre and the need of modern cadastre management,a cadastre-oriented 3D data model(CO3D for short),which extends the OO3D and accord,was proposed.Conceptual and logical model of CO3D were presented in detail,and the implementation of CO3D,including its topology relationship type,storage structure and query method,was studied.Then,the theory of the CO3D visualization was discussed.Finally,a practical experiment was adopted to prove the validity and feasibility of the model proposed in this paper. |
