| 摘 要： | 对地理信息进行编码，是ＧＩＳ设计中最重要的技术步骤之一，它代表着现实世界与信息世界的界面。本文从地图的模型化和空间认知过程出发，提出地理实体编码模型与图形实体编码模型的概念，并着重分析了代表这两类不同编码方式的软件对制图功能的影响，并在此基础上提出了地理属性和地图图形属性耦合的信息编码概念模型。

| Abstract: | Spatial information encoding which presents the interface between the real and information entities, is one of the most important steps in designing GIS. Most GIS and mapping systems almost adopt the ways of encoding for geographical attributes, which are more effective for spatial analyses but weaker in mapping. Referring to the other coding methods such as AutoCad and MapCad, the authors raised the concepts of geographical entity encoding model(GEEM) and cartographic entity encoding model (CEEM), and compared their advantages and disadvantages in mapping. A new model, coupled geographical-cartographic attributes encoding model (CGCEM), has been proposed based on the two models mentioned above. |
