The need for 3D Land Administration Systems (LAS) is growing. In this respect, research is carried out in the field of 3D LAS with respect to data sources, registration of 3D Rights, Restrictions and Responsibilities and dissemination services. Within this context, BIM/IFC models are considered promising sources for 3D LAS, even though the reuse of such models from practice has not yet been examined adequately. Evaluating BIM/IFC-models from practice is crucial, since they are created for different purposes, fulfilling various design criteria. This paper investigates the technical challenges encountered when using real-world BIM/IFC-models for apartment rights’ registration in a 3D LAS. It addresses the validation of five Dutch real-world BIM/IFC-models against four technical criteria, namely: existence of IfcSpace; geometric validity; no overlap and georeferencing. The results of the validation show that the collected BIM/IFC-models lack georeference, IfcSpace and a reference to attributes related to the respective legal units in the Dutch 3D LAS. After validation the models are stored in a 3D LAS Database management system (DBMS), in which the legal spaces are enriched with information of the Rights, Restrictions and Responsibilities (RRR’s) in line with the Land Administration Domain Model (LADM - ISO 19152:2012). The contents of the 3D LAS DBMS are visualised in a web viewer. Additionally, the design for a webservice is introduced, aiming to automate the process of validation, conversion and visualisation. The paper concludes with recommendations and guidelines for creators of BIM/IFC-models based on the outcome of the validation, as well as challenges and recommendations for implementing a validation webservice.

BIM/IFC 作为在 3D 土地管理系统中注册公寓权利的输入 – 原型网络服务


对 3D 土地管理系统 （LAS） 的需求正在增长。在这方面，在 3D LAS 领域开展了有关数据源、3D 权利注册、限制和责任以及传播服务的研究。在这种情况下，BIM/IFC 模型被认为是 3D LAS 的有前途的来源，尽管尚未充分检查此类模型在实践中的重用。从实践中评估 BIM/IFC 模型至关重要，因为它们是为不同的目的创建的，满足各种设计标准。本文研究了在三维 LAS 中使用真实世界的 BIM/IFC 模型进行公寓权利登记时遇到的技术挑战。它解决了根据四个技术标准对五个荷兰真实世界 BIM/IFC 模型的验证，即：IfcSpace 的存在;几何效度;无重叠和地理配准。验证结果表明，收集的 BIM/IFC 模型缺乏地理配准、IfcSpace 和与荷兰 3D LAS 中相应合法单位相关的属性的引用。验证后，模型存储在 3D LAS 数据库管理系统 （DBMS） 中，其中法律空间根据土地管理领域模型 （LADM - ISO 19152：2012） 丰富了权利、限制和责任 （RRR） 的信息。3D LAS DBMS 的内容在 Web 查看器中可视化。此外，还介绍了 Web 服务的设计，旨在自动化验证、转换和可视化过程。本文最后根据验证结果为 BIM/IFC 模型的创建者提供了建议和指南，以及实施验证 Web 服务的挑战和建议。
