多层次空间数据库更新管理与服务平台初探

Research on updating management and service platform of multi-layer spatial database

随着数字城市地理空间数据框架建设的推进,各城市将形成面向多层次应用的城市空间数据库。针对城市空间数据更新体系存在的问题,提出了多层次城市空间数据库更新管理与服务平台模型,通过构建多层次城市空间信息本体库,设计城市空间信息语义层次结构模型及相关的推理算法,解决了多层次、多主题空间数据之间的更新管理,可为数字城市、智慧城市应用提供最鲜活的数据。

With the development of geospatial data framework for ＂ digital city＂ , the urban spatial database with multi layer applications will be established in various cities. This paper proposed a model of updating management and service platform of multi layer urban spatial database according to the problems in urban spatial data updating system. Urban spatial information se mantic hierarchical model and reasoning algorithm was designed through the construction of multi layer urban spatial database ontology library. The updating management of muhi layer and multi theme spatial data was realized, which can provide the tYeshest data for the application of ＂digital city＂ and ＂wisdom city＂.
