建筑三维产权体空间关系剖析

Analysis of Spatial Relationships of 3D Building Properties

城市土地的立体化开发利用促使土地管理模式由平面管理走向更精细的空间管理,当前的建造技术支持了各种形体的建筑建设,为三维产权空间管理提供了现实案例。三维地籍的核心是对产权体的描述与管理,本文从现实的多个三维建筑形体出发,从建筑物的三维产权体与地表形态的关系、与地表的方位关系以及与地表宗地的对应关系3个角度讨论建筑产权体的空间关系分类,围绕三维产权体可能的空间形态开展分析研究,以便快速了解各类复杂建筑和产权体的显著特征,有助于准确描述产权体的空间状况及权利划分状况。

With 3D utilization of urban land,land administration tends to transform from 2D model to 3D space which is more precise.Modern building and construction technology supported various 3D shapes,and many application cases of 3D building properties provide new challenges for our land administration.The cores of 3D cadaster are the descriptions and management of 3D building property.This paper focuses on the application cases of 3D building properties,and analyze them from morphological aspect.This paper first analyzes the relations between 3D properties and earth surface,and the location relations between 3D properties and earth surface form,and the correspondence between 3D properties and earth surface parcel,then classifies the category according to these three profiles,which would promote the understandings of complex buildings and 3D building properties and would enhance the descriptions and the segmentation of 3D building properties.
