Abstract

Real estate units are the elementary management units of uniform real estate registrations that include land and fixed objects such as aboveground buildings. Three-dimensional real estate objects better represent real estate units with complex structures and are suitable for ground-based, aerial and underground registrations of 3D real estate property rights. In this paper, 3D real estate data modeling and representations are investigated in detail: A conceptual model for 3D real estate objects based on the land administration domain model proposed by the International Organization for Standardization (ISO) Geographic Information System Technical Committee (ISO/TC211, Geographic information/geomatics, new work item proposal, geographic information—Land administration model (LADM), ISO/TC211, N 2358, 2008-02-01, 2008) and on the “integrated property and land” conditions in China is considered; rights and property/land relationships are elaborated and extended; within a geometric model of 3D real estate objects, a 3D model of regular real estate units is created from a 2D base map via height extrusion; and a physical model of complex irregular real estate units is created via a convex hull of triangulated tetrahedrons. 3D real estate data modeling has broad applications in areas such as property tax, real estate development and urban planning.
