摘要
地籍管理中核心要素宗地的几何空间和属性信息具有典型的时空特性.以往宗地时空变化的研究主要集中在表达宗地的某一方面,对宗地所有属性和几何空间信息时空变化的表达需要加强.同时,移动对象理论在表达宗地时空变化的研究与应用还没有,且在表达多个对象间同步变化时仍需进一步研究.针对这2个问题,分析了宗地时空变化的类型,提出了基于移动点对象的单个宗地几何空间和属性(单一属性和权属)信息时空变化表达方法以及基于事件的多个宗地间时空变化表达方法,并研发了地籍宗地时空管理原型系统,验证了文中提出理论方法的可行性和有效性.
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.
