Visualization for the Coherent Set of 3D Property Units

There are many 3D objects with denser aggregation that they are fully/partly coherent touched with each other through shared facets, which we called coherent set of 3D objects. Visualization for 3D property unit is an effective way to understand 3D spatial occupation, location and relationship in urban space, particularly in the coherent set of...

The Applications and Practices of 3D Cadastre in Shenzhen

As the economy and urbanization develop, the expansion of the city not only develops towards the horizontal space, but also towards the vertical space. Facing the development of three-dimensional (3D) space, the traditional two-dimensional (2D) cadastral management mode cannot satisfy the need of current 3D land use and urban plan, so developing...

The Conversion from CityGML to 3D Property Units

Due to the fast growth of building construction technology and increasing demands on the efficient use of land, human living space are expanded from on the surface to above and under the earth surface. It raises the need for three dimentional (3D) cadastral by realizing that the current cadastral system based on 2D is not appropriate to reflect...

Topological Relationship Identification in 3D Cadastre

With the accelerated urbanization process, the trend of three-dimensional land use makes the traditional model of 2D cadastral management encounter challenges, because of insufficiency to express in 3D. Therefore, the 3D cadastre and related concepts have been proposed. The breadth and depth of its research are gradually broadened and refined....

Application of 3D GIS to 3D Cadastre in Urban Environment

Rapid development has promoted the 3D land use in the urban environment with the increasing requirements of the complex interweaving, such as dwellings, commercial areas, public transportation and urban utilities and infrastructure.3D cadastral object are features which concern unban planning, land resource and real estate of municipalities,...

AMulti-jurisdiction Case Study of 3D Cadastre in Shenzhen, China as Experiment using the LADM

With the increasing urban population, and the urban exploitation and utilization, especially in the subsurface and the air, various spaces above and below each other are built and belonging to different owners or users. Although the traditional 2D cadastre still plays a dominant role in land administration, urban resource and space management,...
