The Applications and Practices of 3D Cadastre in Shenzhen
Renzhong Guo et al.
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 a 3D cadastral management mode is very imperative. In 2012, Shenzhen city of China puts forward a 3D cadastral management prototype to meet the requirements of 3D land use. After two yearss developments, the focus of 3D cadastre in Shenzhen moves from research and prototypes toward the implementations and the uses of practical systems Shenzhen forms a special model for 3D cadastral administration up to now, based on the needs of businesses for 3D land planning and use. In this paper, business workflow and legal supports are introduced firstly as they offer the explicit direction for development of 3D cadastral administrative system. Then, 3D cadastral data and modules of 3D cadastral system are discussed. Based on current business requirements and 3D technology, the 3D cadastral administrative system includes three modules: 3D data generation module, 3D query-platform and 3D mapping module, and all these modules are built based on the 3D land and planning database. Besides, the cadastral system integrates 3D land planning and management with a 2D environment. This 3D/2D land administration system is deployed in the office automation system for routine management.
