多媒体电子地图使用者和地图界面之间的操作性交互是实现高层次地图交互的基础,地图系统界面的交互性是提高使用者操作性交互效率的关键。本文以系统方法为指导,提出了交互界面的设计流程,包括需求分析、概念模型设计和详细界面设计三个阶段,结合地图使用者的特点,讨论了交互方式和交互形式的选择与配合以及界面隐喻的原则,重点提出了地图可视化系统中界面交互性的设计原则。作者希望本研究能够用于地图可视化系统设计过程中交互界面的设计,从而促进多媒体电子地图交互效率的提高。 相似文献

在现今出版的地图左(右)下角皆可看到的"图例",明代罗洪先的<广舆图>中称之为"省文",即通过对图例的察视,可领会地图所要表达的意义.在明朝以前的中国古代地图里,似乎还没有明确标示于地图上的图例,但这并不影响我们对它的审视,因为中国古代地图大多以很形象的方式表达出来,有的还注明"某水""某河"等,使读者一目了然. 相似文献

一、前言分级统计制图法是定量专题制图中经常采用的一种方法,适用于数据为离散分布且以一个明确的计数单元统计的地理主题,在科研、教学以及有关部门的宏观规划中得到了广泛的运用。分级统计地图图例的制作过程一般包括:数据的预处理、确定分级间距、符号设计与量表、图例设计等工作。目前一些分级统计制图的地图作品,分级 相似文献

ABSTRACTMap legends are key elements of thematic maps and cartographic communication. The question of how to style map legends is a topic which has often been addressed by cartographic academics and practitioners. Nevertheless, the question of where to position a map legend has only hardly been discussed. Principles of cognitive sciences allow the assumption that a legend positioned to the right of a map field can be read and decoded faster than a legend on the left side. This study investigates the impact of legend positioning on legend decoding. It involves an experiment based on a recognition memory paradigm and the registration of eye-movements. The results show that, in less time, a legend positioned to the right of the map field (compared to a left legend) can be decoded faster. The same accuracy of a cognitive representation of geographic space can be achieved in spatial memory. 相似文献

AbstractThe legend is a critical tool in reading and interpreting a thematic map. The goal of the study reported here is to understand how the legend works as a map is read. The methodology combined usability performance metrics with the thinking aloud method. Subjects were asked to perform two sets of tasks using two thematic maps with different legend layouts. While latency and accuracy of answers for the first set of tasks did not differ significantly between users of the different layouts, users clearly preferred legends that were simple or familiar. The thinking aloud protocols from the second part of the study revealed different patterns of legend comprehension for each legend design. In addition, the study identified four problem-solving strategies that were adopted by the subjects. Finally, some principles for designing legends were developed from the results of the study. 相似文献

电子地图符号体系与符号库标准的研究 总被引:11,自引:0,他引:11
在地理信息技术发展的推动下,电子地图的制作和应用日益普及,电子地图符号的规范化势在必行。在传统纸张地图图式规范的基础上,参照国际类似的标准文本,为使电子地图符号适应技术环境和视觉环境的变化,我们对此进行了适当改进,原则继承纸张地图符号的内容分类体系和形状分类体系,延续阅读地图的信息传输和读者认同的习惯。在深入审视符号对视觉产生的复杂作用的基础上,对基本符号实体内容适当简化,对色彩、图元组合关系适当调整,在通用地理信息系统软件平台上制作了基本地理底图的符号库标准草案。 相似文献

Legends are important for understanding maps. Legend design is a part of map design and forms an important topic of cartographic research. Most research on legend design concentrates on the development of techniques rather than the development of basic principles. This study is devoted to the latter topic. Particularly, attention is paid to the development of spacing and alignment rules for effective design of legends shown on screens (computer monitors and tablet screens). Based upon Gestalt laws and Bumstead’s rules, a set of spacing and alignment rules is developed. Experimental evaluations are conducted, and the results indicate that a legend designed with proper consideration of the spacing and alignment rules is much more effective and efficient than ordinary legends. 相似文献
