以基础地理数据为例,在研究现实世界-计算机世界-数据库中事件-变更操作-要素之间的逻辑关系的基础上,通过建立要素信息表、事件信息表以及包含事件关联、事件约束的事件树索引体系,提出并实现了面向事件的地理要素的时空回溯方法,为地理要素的时空查询与回溯奠定了基础.

Taking fundamental geography data as example, the logical relationship among events, chaning operations and features that are in real world, computer world and database is analyzed. The feature information table, the event information table and the event-tree with relations and restrictions are constructed. The event oriented spatio-temporal retrospect method of geographical feature is proposed which can contribute to spatio-temporal inquiry and retrospect.
