| 摘 要： | 从地理信息共享、地理信息标准化研究的角度,着重分析了地理信息在GIS系统中的描述机制,讨论了地理目标、地理实体、地理现象的概念及其间的关系。认为GIS对地理现象的描述是以地理实体及其关系为基本单元的,而地理实体则由表示空间位置形状及空间关系的空间目标及描述物理属性的属性数据共同表示的。

| Abstract: | In view of geographic information sharing,geographic information standardization,a discussion on the issue of GIS representation of geographic information has been made in this paper.The standard concepts of geographic object,geographic entity and geographic phenomenon have been defined.It is concluded that the geographic phenomena are defined by the geographic entities as well as the relationships between them in a GIS. A geographic entity is defined by some spatial objects which represent the spatial location,the shape and spatial relationships of the entity as well as the attribute data with them. |
