This paper presents a 3D cadastral data model for buildings. A review of the relevant research shows that a common concept in the 3D cadastre domain is using the legal building unit, i.e. real property unit, as the core modelling unit. Alternatively, this study proposes using indoor space as a core modelling unit. The main reason is to enable the efficient integration of cadastral data with the data from other domains. On the conceptual level, the model is linked to the Land Administration Domain Model (LADM). The integration options are studied for three international standards: IFC, CityGML and IndoorGML.

室内空间作为3D地籍中建筑物建模的基础

本文提出了建筑物的3D地籍数据模型。对相关研究的回顾表明，在3D地籍领域中，一个常见的概念是使用法律建筑单位（即房地产单位）作为核心建模单位。或者，本研究建议使用室内空间作为核心建模单元。主要原因是要使地籍数据与其他域的数据有效集成。在概念上，该模型链接到土地管理领域模型（LADM）。针对三种国际标准研究了集成选项：IFC，CityGML和IndoorGML。
