Querying 3D Cadastral Information from BIM Models

Abstract

There has been significant research on the intersection of 3D cadastre and building information modelling (BIM) over the recent years. BIM provides a multidimensional environment for capturing, curating and communicating the physical and functional aspects during a building’s lifecycle. A BIM-based solution for 3D cadastre provides a rich repository of legal and physical datasets in a common environment. The knowledge encapsulated inside a cadastral BIM model should be tapped to unlock the value of 3D cadastral information. Therefore, this article aims to develop BIM-based queries for interrogating questions about the legal ownership of properties inside multistorey buildings. These queries include identifying legal spaces that belong to a private or common property; querying physical elements that bound a legal space; and finding legal spaces that are adjacent to each other at a specific building element.

Indoor space as the basis for modelling of buildings in a 3D Cadastre

“…All studies identified the IfcSpace as the most important class for the integration of IFC with RRR data. Atazadeh et al (2019) propose an approach that uses IfcSpace and IfcZone classes and is aligned with our modelling approach. The authors establish a link with LADM classes, by linking IfcSpace with the LA_LegalSpaceBuildingUnit class and IfcZone with LA_BAUnit (Fig.…”

Visualization of 3D Property Data and Assessment of the Impact of Rendering Attributes

“…Instead of manipulating the geometric layout of the visualization model, Wang et al (2016) suggested using transparency as a visual variable not only to encode data but also to relieve the occlusion inherent in 3D visualizations of cadastres. Accordingly, Atazadeh et al (2019) and Vandysheva et al (2011) found mixed transparent and opaque object representations useful to simultaneously visualize structural and legal boundaries in a 3D BIM visualization.…”

“…Another difference between GIS and BIM is the access to data: Data is accessed with different objectives and subsequent requirements. (Atazadeh et al, 2019) conclude in their article on "Querying 3D Cadastral Information from BIM Models":…”
