ABSTRACT

Making and sharing maps is easier than ever, and social media platforms make it possible for maps to rapidly attain widespread visibility and engagement. Such maps can be considered examples of viral cartography – maps that reach rapid popularity via social media dissemination. In this research we propose a framework for evaluating the design and social dissemination characteristics of viral maps. We apply this framework in two case studies using maps that reached wide audiences on Twitter. We then analyze collections of maps derived from and inspired by viral maps using image analysis and machine learning to characterize their design elements. Based on our initial work to conceptualize and analyze virality in cartography, we propose a set of new research challenges to better understand viral mapmaking and leverage its social affordances.  相似文献

Abstract

While concepts and theories about design underpin the work of the professional cartographer, it is unrealistic for most map-makers to be cognisant of the plethora of techniques available to support excellence in design. In the second part of our paper to reassert the relevance of design in cartography, we present the results of a survey of cartographic experts drawn from the academic and professional world. The survey asked participants to present their top ten most expertly designed maps from throughout history. Here, we share the most frequently cited maps that emerged from that survey and describe why they exhibit design excellence. By showing map-makers a range of high-quality cartographic work, we aim to provide exemplars that demonstrate how design affects a map and expertly marries form with function. The techniques on display are well executed and create products that are both well suited to their purpose and have an aesthetic quality that invites people to take notice. They are all, in their own ways, beautiful examples of the art of design in cartography. We have deliberately avoided a ‘top ten’ approach and, instead, offer three examples in a range of map categories. The examples are neither definitive, nor exhaustive and should act as a starting point to explore design in cartography from those who have managed to set the bar high.  相似文献

Abstract

Cartographers have always been concerned about the appearance of maps and how the display marries form with function. An appreciation of map design and the aesthetic underpins our fascination with how each and every mark works to create a display with a specific purpose. Yet debates about what constitutes design and what value it has in map-making persist. This is particularly acute in the modern map-making era as new tools, technology, data and approaches make map-making a simpler process in some respects, yet make designing high-quality maps difficult to master in others. In the first part of a two-part paper, we explore what we mean by map design and how we might evaluate it and apply it in a practical sense. We consider the value of aesthetics and also discuss the role of art in cartography taking account of some recent debates that we feel bring meaning to how we think about design. Our intent here is to reassert some of the key ideas about map design in cartography and to provide a reference for the second part of the paper where we present the results of a survey of cartographers. The survey was used to identify a collection of maps that exhibit excellence in design which we will showcase as examplars.  相似文献

ABSTRACT

In this article, we describe some ideas based on Bertin’s Sémiologie Graphique with a focus on extending it for aesthetic quality issues in cartography. We consider research in semiotics, aesthetics, and graphic design, with some fruitful results about the use of color or composition. We present several tools, oriented toward a pedagogical use and accessibility, helping to examine the color composition of an expressing image or to create meaningful gradients. While Bertin’s concepts still remain relevant and efficient, specific ideas can be developed further, to adapt to current media and gain from scientific advances from related disciplines.  相似文献

A second installment on the theory of scaling in cartography (see MSRS, 1987, No. 2, pp. 104-111) focuses on the design of scaling (symbolization) systems. Attention is devoted to the reasons for the lack of correspondence between numerical relationships of values being depicted on maps and quantitative relationships in the scaling system(s) used to represent them. The most visually dominant attributes of symbols (form, color) in the scaling system should be used to represent the most dominant characteristic of the mapped objects. A final section contains recommendations for symbol design at different levels (nominal, ordinal, etc.) of scaling.

Abstract

John Keates is very well known for his numerous scholarly contributions to cartography as an academic discipline and science. However, throughout his career, he was also very actively involved in the design and production of maps. Mostly these were specialized thematic maps produced as the result of scientific research in the field sciences, especially in geology, glaciology and vegetation studies. However, during the 1970s he was much involved in the design and production of a considerable number of maps for recreation purposes, including maps for orienteering. Many of these maps were regarded at that time as being extremely innovative in terms of their cartographic design and layout. The article outlines the development of what became known as the 'Glasgow' style of map design John Keates' involvement with recreation maps in the 1970s.  相似文献

Computer-generated maps have become commonplace over the past decade. Most internet search engines, for example, have the ability to generate maps in response to spatial queries and routes between specified origins and destinations. Advances in mobile computing technologies provide access to these mapping capabilities from virtually any location on the Earth's surface. Maps and map-making have become ubiquitous, and this phenomenon requires cartographers to rethink basic concepts about map design and map use. In this special issue we present five research projects that are focused on the emerging field of ubiquitous cartography. These projects were selected, in part, because they are representative of key research challenges that face the cartographic research community. In this introductory paper, key terms are defined and research challenges outlined. By way of this collected set of papers, ubiquitous cartography is presented as a new and important arena for cartographic research.  相似文献

Abstract

This paper provides an overview of the multiple ways of envisioning the relationships between maps and narratives. This is approached from a map making perspective. Throughout the process of editing this special issue, we have identified two main types of relationships. Firstly, maps have been used to represent the spatio-temporal structures of stories and their relationships with places. Oral, written and audio-visual stories have been mapped extensively. They raise some common cartographic challenges, such as improving the spatial expression of time, emotions, ambiguity, connotation, as well as the mixing of personal and global scales, real and fictional places, dream and reality, joy and pain. Secondly, the potential of maps as narratives and the importance of connecting the map with the complete mapping process through narratives is addressed. Although the potential of maps to tell stories has already been widely acknowledged, we emphasize the increasing recognition of the importance of developing narratives that critically describe the cartographic process and context in which maps unfold - the core idea of post-representational cartography. Telling the story about how maps are created and how they come to life in a broad social context and in the hands of their users has become a new challenge for mapmakers.  相似文献

ABSTRACT

Automatic generation of multi-scale representations from the same spatial data source has been the research focus in map generalization for a long time. Based on the Fourier technique, this paper proposes a continuous, multi-scale representation model for progressive transformation of cartographic curves on the Internet. In our method, all the curves, whether closed or open, are depicted as periodical functions which are further expressed as Fourier series. The convergence degrees of the Fourier series are explored for different kinds of curves, and truncating frequencies are derived based on the similarity between the original and reconstructed curves. Using information theory and the Radical Law in cartography, the relationship between map scales and Fourier frequencies is established. Based on the proposed multi-scale model, we also introduce the principles and implementation of a progressive transmission method. Our method is evaluated using the contours from a topographic map. The results show that our model is a valid approach to multi-scale representation of cartographic curves.  相似文献

Abstract

Lenticular visualisation methods are innovative advancements of modern presentation media in cartography. Owing to the mainly three-dimensional perception of people, this technique, in print as well as on screen, offers the possibility to introduce autostereoscopic, i.e. three-dimensional views in cartography. On the basis of true 3D, it has already found its way into the visualisation of relief relations. Moreover, it also opens perspectives for the more widespread products of thematic cartography (thematic maps). Multi-layered representation becomes possible on the basis of three-dimensional or sequentially differentiated depictions of spatial phenomena. Thus, several parameters or dimensions of cartographic content can be displayed at the same time. This essay discusses some potential applications of the lenticular foil technique for thematic cartography on a theoretical basis.  相似文献

Abstract

To what extent do European state topographic maps exhibit unique styles of cartography? This paper describes an investigation to classify and analyse stylistic diversity in the official 1 : 50 000 topographical mapping of 20 European countries. The method involves the construction of a typology of cartographic style, based upon the classification of distinct graphical legend symbols into mutually exclusive thematic categories. In order to identify stylistic similarities between national symbologies, hierarchical cluster analysis was performed to compare the relative proportions of symbols within each category. This was complemented by a qualitative analysis of various aspects of cartographic design: colour, 'white' space, visual hierarchy, and lettering. The results indicate a high degree of stylistic diversity throughout Europe, with the symbologies of Great Britain and Ireland demonstrating the strongest example of a supranational style. The typology of cartographic symbologies is shown to be an effective method for determining stylistic association among maps of differing geographical (and potentially historical) origins and it is suggested that the cartographic language paradigm should be revisited as a means for understanding why national differences persist in state cartography. A version of this paper was presented at the Twenty-third International Cartographic Conference in Moscow.  相似文献
