摘　　要：立足现代地籍管理的需要,基于UML建立了城市三维地籍对象模型。聚焦三维地籍要素类,提出了基于B-rep模型的三维地籍空间数据表达方式,设计了三维地籍数据的属性结构与关系模型,综合建立了三维地籍数据模型。本文研究提出的数据模型,能够为城市三维地籍数据组织、表达与管理提供技术借鉴。A three-dimensional urban cadastre object model is established based on UML according to the needs of modern cadastral management.Focusing on the three-dimensional cadastral feature class,a method for spatial data expression of three-dimensional cadastre based on B-rep model is put forward,the attribute structure and relationship model of three-dimensional cadastre is designed,and a three-dimensional cadastral data model is comprehensively established.The data model proposed in this paper can provide technical reference for the organization,expression and management of urban three-dimensional cadastral data.
