| 摘 要： | 地理信息表达从二维纸质地图到电子地图再到三维可视化地理环境的飞跃,是地图学史上的一次革命。三维空间认知理论,三维符号体系设计及三维符号变量理论的逐渐完善和发展对三维环境下地理空间信息的表达起到了积极的作用,本文论述了二维地图符号与三维空间信息表达的关系,描述了二维地理信息在三维空间中叠加表示的意义,并分析了二维地图符号表达的优劣性。

| Abstract: | The expression of geographical message that from traditional two-dimensional map to the electronic map and three-di- mension visualization geographical environment,is the revolution and leap in the cartology history.Three-dimensional cognize theory, three-dimension symbols system and three-dimension symbol vision variable theory that are more and more consummate are much useful to express the geo-space information in the 3D environment.In this paper,we discuss about the relationship between the 2D symbols and the expression of the 3D space information,describe the meaning in 2D gengraghy information expression in the 3D space,and an- alyze the excellent and inferior about the 2D map symbols expression. |
