| 摘 要： | 事件信息反映了地籍要素发生变化的原因,与变化信息共同构成增量信息.针对目前增量信息变化检测方法尚未实现事件信息检测的问题,提出了一种包含事件信息的地籍数据库增量更新变化检测方法.该方法通过选取“继承关系”、“拓扑关系”与“属性关系”三个因素作为前提条件,建立了地籍要素事件知识规则库,并在检测变化信息的基础上,通过计算三...

| Abstract: | Event information reflects the changing reasons of cadastre,constitutes incremental information together with changing information.However,the method of change detection doesn't realize the detection of event information at present.To address this issue,a new method of change detection including event semantics was proposed in the paper,which could be used in cadastral database incremental updating.Cadastral event knowledge rules database was established in the method which selects 'inheritance relationship','topology relationship' and 'attribute relationship' three factors as prerequisites.On the basis of obtaining changing information,the cadastral event information was deduced by calculating different values of the above factors according to the established parcel event knowledge rules.A prototype was designed and realized,and the experimental results showed that the method could accurately deduce the changing information and corresponding event information of parcels.It provides a solution for the realization of automatic incremental updating cadastral database. |
