【摘要】 房产管理的产权对象在三维空间中的变化具有显著的多样性与异步性特征,已有的模型以二维地图方式表达建筑物整体的动态变化,很难准确有效地表达真三维建筑多重产权实体变更的不同步性。本文充分利用房产对象的空间层次关联性及产权单元的语义约束知识,定义了从地块到幢、层、户和权属的多层次事件概念,建立了三维房产从外至内动态表示的概念模型,为三维城市空间中建筑物的变迁以及房地产权属异动的准确表达与时空分析奠定了基础。更多还原

【Abstract】 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.更多还原
