modelling spatio : temproal aspects for cadastral system in China
Zhang, Ning and Arbind Man Tuladhar
Due to increasing population, industrialization, and urbanization in China, the demand for land resources has become a major limitation to the sustainable economic and social development of China. Chinese government has realized that an efficient management using modern Geo-Information technology for the land resource is vital both for the present and future use of land. Thus efficient and effective management of Cadastral Management System is one of important priority now in China (Zhang, 2006). Cadastral system in China currently operates only with current data not historical data. If it has to relate to the temporal aspects of cadastral land parcel with historical data, it then has to provide the capability to trace the spatial and associated changes in time. It can then be used to anticipate the trends for future strategic planning about the use of land. In this paper, we highlight three main issues. The first issue describes land tenure how Chinese people uses land and deals with land use rights in urban as well as rural areas. The paper then highlights the needs of the Spatio-Temporal Data about the cadastral land objects from the view points of users and land registration in China. Then it describes the Spatio- Temporal Cadastral Data Model (STCDM) using Unified Modelling Language (UML) for static component and Identity-Based Change Model for dynamic part. Finally it concludes that such STCDM is a great demand for Cadastral Information System in Chinese land management (Zhang, 2006).
