摘要
针对GIS中表达时空数据的特殊要求,在MAPGIS7.0的版本化数据管理框架基础上提出了一种基于历史归档的时空数据管理模式,通过建立历史表对地理实体进行生命周期管理,并详细阐述了其实现策略。该方法已经被MAPGIS7.0平台采纳,提供了历史数据归档和历史分析等工具来对历史数据进行管理和分析,能够满足土地利用、人口分析等系统中的时空数据管理需求,证明了该策略的正确性和可行性。
According to the special requirements of Spatio--temporal data in GIS, it is necessary to develop a bran-new spatio--temporal data model, which can be based on history archiving. Actually, it is the history table that organizes and manages those geographic entities or related objects by means of lifecycle management in this spatio--temporal data model. And then the whole model can be implemented based on the version management. With the spatio--temporal data model, it is facile and flexible to provide certain proper function such as history archiving and history＇analysis for managing and analyzing history data. Thus it can be seen that the Spatio-temporal data model will be widely applied in some related fields as land use and vital statistics.
