基于时空拓扑分析的地籍时态查询

Temporal Cadastral Query Based on Spatio-temporal Topology Analysis

通过分析地籍变更的时空拓扑特性,得出了具有父子关系宗地间存在空间上相交和时间上相接两个拓扑约束条件,籍此拓扑约束条件设计了地籍时态查询算法。并在基于地理对象的基态修正时空数据模型的基础上,设计了历史地籍数据库、现状地籍数据库和临时地籍数据库,辅以变粒度区段时态索引对该时态查询算法进行了实现研究。

The spatio-temporal topology characters of the land subdivision is analyzed and It is concludedtnat that there are two topologic constraint conditions among the father-son parcels, which are the overlap on the spatiality and the join with the temporality. A query system for father-son parcels based on the analysis of spatio-temporal topological relation under the guide of father-son parcels spatio-temporal conditions is designed. At the same time, the preliminary functions of temporal cadastre for temporal cadastral query are realized in an experimental system.
