摘要
提出了一种基于空间与时间属性查询的空间矢量数据历史回溯方法,解决了不同时期矢量数据的联动对比分析的问题,帮助使用者掌握数据的历史更迭情况以辅助决策。
In this paper,a historical backtracking method of spatial vector data based on space and time points is proposed,which solves the problem of the correlation analysis of vector data in different periods,and helps to get the historical change information to aid decision.
