Expression of Spatiotemporal Changes of Parcels Based on Moving Point Objects and Events

Abstract:

The key elements in cadastral management, which are the geometric spatial information and attributes of parcels, have typical spatiotemporal characteristics. The current researches on the spatiotemporal changes of parcels mainly focus on the expression of a single aspect of the cadastral parcel. However, the expression of the spatiotemporal changes of all the attributes and geometric spatial information of the parcels need to be strengthened. Meanwhile, little attention is paid to the expression of spatiotemporal changes of parcels based on moving objects theory. And the expression of synchronous changes of multiple objects needs to be further studied. In this paper, as to the two mentioned problems above, the types of spatiotemporal changes of parcels are analyzed. And the method to express the spatiotemporal changes of geometric spatial information and attributes (single attribute and ownership) of a single parcel based on moving point objects is proposed. At the same time, the method to describe the spatiotemporal changes of multiple parcels based on events is presented in this paper. Furthermore, the prototype system of spatiotemporal management of cadastral parcels is developed in this study, which proves the feasibility and efficiency of the proposed methods.
