摘要：

作为一种方法论的探索,以二元分析为基本方法,初步探讨和形成了地理信息可视化二元概念模型 ,力求构建一个简单的、易于被人们理解和接受的地理信息可视化理论框架。文章首先从地理学、语言学、哲学等方面阐述了二元方法论的理论基础,然后以符号语言学为范式,从地理信息可视化的所指与能指两个方面展开,阐述地理信息可视化二元方法论的主要内容;最后得出结论。研究表明:①地理信息具有二元性,它包括时间与空间二元 、瞬时与历时二元、空间几何与空间属性二元、定性与定量二元;②地图设计也具有二元性,它们是地图整体样式与个体符号二元、符号外观与内在二元、形状与尺寸二元、色彩与纹理二元。

Abstract:

As a significant approach to geographic information visualization, map making is practiced by not only professional cartographers but also more and more general public. However, the latter is often rarely equipped with knowledge of cartography. Instead of comprehensive theories and methods of cartography, simplified mapping skill might be suitable for them to make maps with respect to their special purpose. As a preliminary study, this paper aims to explore and build a conceptual model of duality for geographic information visualization. Dualistic analysis is employed to establish an easy-to-be-understood framework which could be followed as a "map-making guide". First, the paper introduces the theories of dualism in terms of other disciplines, such as geography, linguistics and philosophy. Then, with semiotic linguistics as a normal form, the methodology of dualism for geographic information visualization is elaborated from the perspectives of the signifier and signified of geographic information visualization. Our analyses demonstrate that: (1) geographic information is of duality, such as the duality of time and space, the duality of instant and interval, the duality of geometry and attributes, the duality of qualitative and quantitative approaches, etc.; and (2) map design is also full of various dualities such as the duality of the entire format of a map and individual symbols, the duality of outline and fill of a symbol, the duality of shape and size, the duality of color and texture, and so on.
