基于SVG的面状地图符号设计与实现

面状地图符号的设计与实现是计算机地图制图领域研究的基本问题,而面符号的共享则是当前开放地理信息技术研究的重要内容。本文结合面状地图符号设计的基本方法与开放标准的二维矢量标记语言SVG,提出并详细设计了基于SVG的面状地图符号。实验通过基于XML的地图表达原型系统测试,其结果证明能够满足我国地形图图式规范的符号表达要求。

地图面状符号色彩真实度认知及性别差异分析

针对传统地图面状符号色彩设计中理论研究与评价方法滞后、缺少定量分析和个性化差异研究的瓶颈问题,提出了一种基于方差分析的研究方法。首先对地图面状符号色彩真实度认知及性别差异分析现状和存在的问题进行总结。然后采用德尔菲法(专家意见法)确定问卷设计问题;采用问卷调查法收集实验数据;通过描述性统计分析验证地图面状符号色彩设计真实度对于地图整体设计效果的重要性;通过方差分析对地图面状符号色彩真实度感受性别差异的显著性进行研究。实验结果表明:地图面状符号色彩设计真实度非常重要,而且对其感受存在性别差异,与心理学领域的相关结论一致。研究结果对于指导地图面状符号色彩设计和地图个性化设计研究具有重要的参考价值。

A Study on the Usability of Semiotics in Graphic Design

Currently, The current flat design has become a mainstream approach is widely used in web design, computer and mobile phone systems, interface design. In graphic design, graphic symbol design is increasingly being taken seriously and use minimalist design symbols often appear in print design plane, PPT presentations, public areas, identity-oriented system like. This paper discusses the design of graphical symbols flat in graphic design use need to make the audience cognitive ability, graphic symbols standardized principles, design principles angles for effective information design to achieve efficient information communication. Materialized mostly graphic image symbols, and mostly flat graphic indicator; flat screen symbol by the proposed development materialized symbol interface evolved. Materialized the graphical interface and the graphical interface is flat coexist and cannot replace each other. During the design, the designer should be based on the advantages and disadvantages of the two styles complement each other interfaces, common graphical interface design services.

一种适用于航标覆盖范围重叠度表达的离散方法

为了直观准确地表示具有严重重叠现象的航标覆盖范围,提出了一种面状图形离散方法,以放射线型图型为基本图形,在进一步离散中建立航标参数的表达手段,并建立航标覆盖能力的可视化方式。用线离散面、基本图元离散线的离散化方式能节约表示面状要素、线状要素所需的平面空间,可用于处理彼此重叠的面状要素的压盖问题,单一符号离散出的基本单元和图案能用于表示信息的不同,反映航标之间的区别。
