| 摘 要： | 当前的GIS大多基于图层的技术实现历史变化信息的管理,不具有存储单个要素时空属性的机制。对此,改进了ISO的时间模型,并提出了一种时间拓扑关系模型,目的是便于对单个要素的历史信息进行有效的管理。实验表明,该模型可以实现单个要素的历史信息查询。

| Abstract: | The current GIS mostly realize the management of history diverse information by using technology that relies on layer-based approach,it does not have the mechanism to store spatial temporal attributes of individual features.Thus,ISO's temporal models were improved,and a temporal topological relationship model was proposed to manage the individual feature history information effectively.The experiment showed this model was able to realize the queries on individual feature history information. |
