Dynamic Representation of 3D House Properties Based on Hierarchical Events

The traditional dynamic representation model has inhibited the increasing needs of 3D dynamic characteristics of house properties information,such as the multi-scale spatiotemporal features,diversity and asynchrony of partial changes in 3D space,high relevancy among change events.We propose a novel dynamic representation of 3D house property based on hierarchical events,which are characterized by land-block event,building event,storey event,unit event and property right event.The experimental results show that this representation is effective to model the detailed 3D dynamic change information of complex buildings and their related house properties.
