A geometric and semantic evaluation of 3D data sourcing methods for land and property information

Abstract

Urbanisation, the development of high-rise apartments and the advent of complex building structures creates unique challenges that cannot be met by 2D land and property information. These include inter-related titles and complex plans relating to (i) the land parcel and (ii) the building, both internal (indoor plans) and external attributes (roof and façade). Incorporating the third dimension into the land development cycle can potentially address such challenges by providing data that describes both the land parcel and building in 3D. This move towards 3D data administration requires the development of new 3D data processes, including 3D data sourcing, which forms the focus of this research..
