In ancient time, toponomy ,maps and geography are all the learning of disclosing the geographic entities.According to the analysis of the documents of both the ancient time and nowadays,the course which mankind recognises geographic entity starts with individuality and studies on each individuality's spatial relationship,and then discloses the entity's forms, connections and properties. The course of cognition develops just from toponomy to maps, till geography. The original relationships...

In ancient time, toponomy ,maps and geography are all the learning of disclosing the geographic entities.According to the analysis of the documents of both the ancient time and nowadays,the course which mankind recognises geographic entity starts with individuality and studies on each individuality's spatial relationship,and then discloses the entity's forms, connections and properties. The course of cognition develops just from toponomy to maps, till geography. The original relationships disclosed these three sides are all the science of studying on the survival geographic environment for human beings, so they are all important components of geographic science.

认为地名、地图、地理在古代都是揭示地理实体的学问.根据古今文献记载的分析,人类认识地理实体的过程是由个体开始,继而研究各别个体的空间关系,进而揭示实体的构成、联系和性质,这一认识过程正好是由地名到地图再到地理;由其产生的渊源关系也揭示出三者皆是共同研究人类赖以生存的地理环境的科学,故都是组成地理科学的成员

According to definition of geo data model, it has been analyzed that time is a basic property of geographic entity and how to study geographic time in GIS. In the case of reality geographical environment changing fastly and application focusing on analysis of local change, current geo data model have many flaws such as redundant storage of unchanged data、 difficult extraction of temporal information、 implicit representation of temporal property of geographic entity. Based on the law of existing many synchronous changing small units, a temporal geo data model with timestamp on the group of synchronous changing data items and the segmented topological arc is presented, which reduces redundant storage and shows us apparent temporal property of geographic entity.

从地理数据模型的定义出发,阐述时间作为地理实体的基本特征及GIS中地理时间的模拟方法,指出传统地理数据模型在地理环境变化快且应用强调细节变化分析的场合,表现出不变数据的冗余存储、局部变化信息提取困难及地理实体的时间特征表现不明显等缺陷。基于现实世界中存在诸多同步变化的细小单元这一规律,提出一种基于属性同步数据项组和空间碎分拓扑弧段时间标记的时态地理数据模型,它降低了存储冗余且较好地表现了时间特征

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.

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。
