We are proud to announce that Silvia Klettner’s research on cartographic semiotics received TU Wien’s Best Paper Award 2019 from the Faculty of Mathematics and Geoinformation:Continue reading “Best Paper Award goes to Silvia Klettner”
Silvia Klettner’s work on the subtle communication effects of map symbols was recently published in the ISPRS International Journal of Geo-Information in the Special Issue on Geovisualization and Map Design: Klettner, S. (2020). Affective Communication of Map Symbols: A Semantic Differential Analysis. ISPRS International Journal of Geo-Information, 9(5), 289.
Maps enable us to relate to spatial phenomena and events from viewpoints far beyond direct experience. By employing signs and symbols, maps communicate about near as well as distant geospatial phenomena, events, objects, or ideas. Besides acting as identifiers, map signs and symbols may, however, not only denote but also connote. While most cartographic research has focused on the denoting character of visual variables, research from related disciplines stresses the importance of connotative qualities on affect, cognition, and behavior. Hence, this research focused on the connotative character of map symbols by empirically assessing the affective qualities of shape stimuli.
On last Thursday 12th the closing event of the EURECA/UGESCO projects was held at Cinematek, the Royal Belgian Film Archive in Brussels. EURECA is an international cooperation of the TU Wien, the Ghent University and several Belgian and Austrian archives focused on revealing inter-regional traces in Europe.
Results were presented by Steven Verstockt, Nico Van de Weghe, Kenzo Milleville, Dilawar Ali, Georg Gartner and Francisco Porras Bernárdez. We will extend further our excellent cooperation with our colleagues.

This year’s 29th International Cartographic Conference (ICC) took place in Tokyo, Japan, with over 950 participants. The members of the Research Division Cartography and its affiliates also contributed their latest works by Scientific Presentations, Scientific Posters, Maps, and Atlases. With a Position Paper, the research group also participated in the pre-conference workshop in Beijing, China on “User Experience Design for Mobile Cartography: Setting the Agenda”.

Location Based Services are a main research focus of the Research Division Cartography as our recent publications in the field show:
User-centred design for smartwatch-based pedestrian navigation
The characteristics of a smartwatch impose several challenges regardig the design of a pedestrian navigation aid. This paper illustrates how landmark-based pedestrian navigation systems for smartwatches can be developed, considering the small screen sizes as well as the very limited interaction capacities of these wrist-worn devices. Particularly, by the use of a user-centred design approach, an initial user interface was developed, tested, and refined in two field experiments to create a final user interface. A combination of map view and direction view was proposed, where the map view provides an overview of the environment and route, while the direction view gives clear instructions (turning information) for decision points. The interface was further enhanced by the use of vibrations before decision points. In addition, landmarks were carefully considered and incorporated into both map view and direction view. The field experiments showed that these key features of the revised interface can effectively support pedestrian navigation via smartwatches.

A research agenda for Location based services
We are now living in a mobile information era, which is fundamentally changing science and society. Location Based Services (LBS), which deliver information depending on the location of the (mobile) device and user, play a key role in this mobile information era. This article first reviews the ongoing evolution and research trends of the scientific field of LBS in the past years. To motivate further LBS research and stimulate collective efforts, this article then presents a series of key research challenges that are essential to advance the development of LBS, setting a research agenda for LBS to ‘positively’ shape the future of our mobile information society. These research challenges cover issues related to the core of LBS development (e.g. positioning, modelling, and communication), evaluation, and analysis of LBS-generated data, as well as social, ethical, and behavioural issues that rise as LBS enter into people’s daily lives.

Silvia Klettner’s work on inherent qualities of geometric shapes for cartographic representations was successfully published in the ISPRS International Journal of Geo-Information 2019, 8(5), 217 in the Special Issue on Human-Centered Geovisual Analytics and Visuospatial Display Design:
All human communication involves the use of signs. By following a mutually shared set of signs and rules, meaning can be conveyed from one entity to another. Cartographic semiology provides such a theoretical framework, suggesting how to apply visual variables with respect to thematic content. However, semiotics does not address how the choice and composition of such visual variables may lead to different connotations, interpretations, or judgments. The research herein aimed to identify perceived similarities between geometric shape symbols as well as strategies and processes underlying these similarity judgments. Based on a user study with 38 participants, the (dis)similarities of a set of 12 basic geometric shapes (e.g., circle, triangle, square) were examined. Findings from cluster analysis revealed a three-cluster configuration, while multidimensional scaling further quantified the proximities between the geometric shapes in a two-dimensional space. Qualitative and quantitative content analyses identified four strategies underlying the participants’ similarity judgments, namely visual, affective, associative, and behavioral strategies. With the findings combined, this research provides a differentiated perspective on shape proximities, cognitive relations, and the processes involved.
Über vier Jahre hat kollektiv orangotango sogenannte counter-cartographies – widerständige Kartierungen – aus der ganzen Welt zusammengetragen. Die Sammlung zeigt, wie kritische Karten gemacht und genutzt werden – als Teil von politischen Kämpfen, kritischer Wissenschaft, Kunst und Bildungsarbeit. Der kürzlich im Transcript-Verlag erschienene Atlas enthält auch einen Beitrag von Florian Ledermann zu einer Karte aus dem genderATlas.Continue reading “This Is Not an Atlas ‒ eine globale Sammlung widerständiger Karten”
We are proud to announce that PhD candidate and lecturer Florian Ledermann has won the award for “Best Student Paper” at this year’s GI_Forum conference in Salzburg, Austria. The jury unanimously voted for his paper “Analysing Digital Maps Online: A Reverse Engineering Approach” and praised the author’s accomplishment of making the complex workings of online maps transparent to a wide audience. A preprint of the paper, which will appear in print later this year in the GI_Forum journal, is available here.
