Classification and Identification of Cadastral Structure Change

Cadastral topological structure change is the foundation for conducting change analysis, and updating data in Cadastral Information Systems (CIS), and it almost happens every day in many cities. In this paper, we subdivide cadastral structure changes into small structure change and large structure change according the parcels involved in the transition. The classification methodology of small cadastral structure change is discussed; the sub-classifications of the small structure change are concluded and proved at a given level. The semantic of sub-classifications of small cadastral structure change is described. The identification algorithms for the subclassifications of small cadastral structure change used in change reasoning and updating are described. The typical cases of large cadastral structure change are concluded. Then we use the incremental updating of small rectification as an example to illustrate how the sub-classification of cadastral structure change can be used to improve the procedure for updating cadastral databases.
