动态基态修正的地籍时空数据库设计

Design of Cadastral Spatio-Temporal Database in Dynamic Data Models of Base State with Amendments

针对地籍数据的时态特性及变更特点,提出了一种基于基态修正的地籍时空数据模型的改进方法,通过引入动态变粒度方法减少了数据存储量,降低了数据的冗余。基于该模型在建库过程中引入了基态库和差文件库,并利用动态属性数据对现势库和历史库中的宗地属性数据进行地籍管理;通过建立变更库确定父子宗地,加强现势库与历史库的时态关联,提高了数据的检索速度。

Cadastral data for the temporal characteristics and changes in characteristics,the paper present a modified ground state based temporal data model for cadastral improved method,by introducing the dynamic variable granularity approach reduces the amount of data storage,reducing data redundancy.Based on the model in building a database during the introduction of the ground state library and the poor library and dynamic property data on the current situation libraries and historical library parcel attribute data for cadastral management;through the establishment changes to libraries to establish paternity cases,the strengthening of the current situation library When the state library and historical association,to improve the data retrieval speed.
