| 摘 要： | 时空数据模型是建立TGIS的基础。首先指出了建立时空数据模型中应该考虑的问题,同时指出面向对象时空数据模型的优越性;然后提出了面向对象的时空数据模型。指出地理世界抽象是由时空属性对象组成,每个时空属性对象由空间、属性、时间3部分组成。系统分析了时空属性对象各个组成部分之间的关系并通过UML进行了表达。最后,以地籍管理中的宗地为例说明了该数据模型的实现。

| Abstract: | Spatial-temporal data model was the foundation of TGIS.The paper discussed some problems which should be considered,the advantages of object-oriented method in spatial-temporal data modeling.Then,the paper proposed an object-oriented spatial-temporal data model which considered that geographic space was made up of spatial-temporal-attribute-object which included three components,such as space,attributes and time.And the paper discussed the relations of each components of spatial-attribute-temporal-object and expressed them in UML.Finally,the paper discussed the implementation of this data model in cadastral management. |
