摘要
通过分析地块变更的时空变化过程,总结出具有父子关系的时态地块的空间相交性和时间相接性特点,归纳出查询这种关系的约束条件。利用扩展时空复合模型和元组时区标记,借助于变更地块的约束条件,设计出查询变更地块的时态链算法。
By analyzing the spatio temporal process of land subdivision, this thesis sums up the properties of spatio overlap and time meet of temporal land parcels, summarizes the spatio constriants and temporal constriants of querying this type of parcels. Based on the extended space time composite model and tuple time stamp, algorithms that query the chain of spatio temporal of land subdivision are designed in term of the condition of constriants.
