3D BIM-enabled spatial query for retrieving property boundaries: a case study in Victoria, Australia

Abstract

In the cadastral system of Victoria, the legal extent of properties is defined by a wide range of property boundaries referencing physical objects. These boundary types are typically represented in 2D plans. However, to address the challenges of 2D plans in complex buildings, there has been a growing trend towards the adoption of 3D models. These 3D models have been mainly used for visualization purposes, with no spatial query developed for identifying property boundaries in 3D models. Among 3D models, the Building Information Modelling (BIM) environment provides the potential capabilities for modelling property boundaries. In this paper, a spatial query approach predicated on topological re..
