摘要
Traditional cadastre is based on 2D parcel subdivision at a certain moment. It does not support 3D property management and spatio temporal query. It is necessary to explore 4D (3D space + time) cadastre. 4D parcel is the registration object of 4D cadastre, which is the extension of parcel in 4D space, and its creation, segmentation, merger and logout are the most common functions of 4D cadastre. According to the urban development status and cadastral management requirements, this paper analyzes the characteristics of temporal property right, and UML is used to model 4D parcel and operation algorithms based on topological data model are discussed. Research contents are as follows:① Data model of 4D parcel is proposed. ② The creation algorithm based on push and shared topology primitives processing method based on segmented time is put forward.③ Four-dimensional patrimong segmentation and merging algorithm is also raised. It is concluded that the construction of 4D parcel provides theoretical reference and technical support for tracking the spatio temporal changes of property rights and takes a step forward to 4D cadastre. © 2019, Editorial Department of Wuhan University of Technology.
