This article presents an empirical study that looks at the question of how prosumers and cartographers use the graphical variables developed by Jacques Bertin in 1967 for cartographic communication. The findings suggest that both prosumers and trained cartographers mainly use the graphical variables colour hue and shape. Trained cartographers additionally use the graphical variables size and colour value to represent ordinal, nominal, and numerical data. The persistence of this difference speaks to the continued importance of cartographic training for effective cartographic communication.

A building label placement method for 3D visualizations based on candidate label evaluation and selection / Jiangfeng She in International journal of geographical information science IJGIS, vol 33 n° 10 (October 2019)

However, building label placement is much more complex in 3D scenes than in two-dimensional (2D) maps. The annotation effect is influenced by the attributes of the 3D label, building visibility, and the spatial relationship between the building and viewpoint. In this context, automatically generating building labels for 3D scenes during interactions requires highly complex computations. By contrast, evaluating candidate labels and then selecting the suitable label for each building can be effectively implemented. This paper introduces an approach for labeling buildings in 3D scenes based on evaluations of label candidates. The proposed method predefines a candidate label set for each building. These candidates are then evaluated in terms of their attributes and the relationship between the labels and viewpoint at runtime. The best candidate label, or a situational alternative for each building, is then placed in order of comprehensive label priority to avoid annotation conflicts. A series of experiments demonstrate that this method effectively enhances the correlation of labels and buildings, improves interactive efficiency, and realizes a viable global label layout.

Graphically supported evaluation of mapping techniques used in presenting spatial accessibility / Lukasz Wielebski in Cartography and Geographic Information Science, Vol 46 n° 4 (July 2019)  

Public [article]  inCartography and Geographic Information Science > Vol 46 n° 4 (July 2019) . - pp 311 - 333 Titre : Graphically supported evaluation of mapping techniques used in presenting spatial accessibility Type de document : Article/Communication Auteurs : Lukasz Wielebski, Auteur ; Beata Medyńska-Gulij, Auteur Année de publication : 2019 Article en page(s) : pp 311 - 333 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Rédaction cartographique [Termes descripteurs IGN] accessibilité [Termes descripteurs IGN] analyse spatiale [Termes descripteurs IGN] charte graphique [Termes descripteurs IGN] conception cartographique [Termes descripteurs IGN] lisibilité perceptive [Termes descripteurs IGN] questionnaire [Termes descripteurs IGN] test de performance [Termes descripteurs IGN] visualisation cartographique Résumé : (Auteur) Given the rising availability of alternative ways of spatial data mapping, there is a growing need to study their usability. An important aspect here is the diversity of the cartographic visualizations that are used to draw conclusions about the usability of various mapping techniques. In our study we evaluated the usability of six various mapping techniques used in presenting spatial accessibility, taking into consideration four components: effectiveness and efficiency (objective criteria) and graphical attractiveness and user-perceived effectiveness (subjective criteria). Using Internet questionnaires, we conducted a graphical perception experiment with respondents performing tasks on a hypothetical monocentric road network model displayed using mapping techniques of spatial accessibility, differing in the applied parameters of graphical and non-graphical factors influencing effectiveness and efficiency. The results showed that non-graphical factors had a greater influence than the graphical factors. In total usability comparison the three-dimensional (3D) point technique was ranked the highest, while the worst result was achieved by the 3D area technique. The proposed graphical form of study results made it possible to compare the influence of various effectiveness factors, to analyze mapping techniques in terms of considered criteria and finally to present their total usability using a chart inspired by Uhorczak’s typogram.

Map symbols for crisis mapping : challenges and prospects / John C. Kostelnick in Cartographic journal (the), Vol 56 n° 1 (February 2019)

However, effective map symbology for humanitarian relief purposes entails several challenges, including consideration of the following: (1) taxonomy development, (2) symbol design issues, (3) promulgation and sharing of map symbols, and (4) standardization of symbols within and among organizations. This paper discusses these key challenges to the design and use of crisis map symbology through a review of the cartographic literature as well as results collected from a survey targeted at humanitarian organizations from around the world. The survey was designed to gather information on current symbology design and use practices in order to understand common challenges. Survey results confirm agreement in the persistence of these four primary symbology challenges, especially the importance of intuitive symbol design. Respondents disagreed most about the adequacy of current crisis map symbology standards as well as the ease in which standards may be implemented within and across organizations. Survey results suggest the need for expert systems designed specifically for symbology design to support humanitarian relief activities.

In the field of toponymy, this requires, in particular, thinking of categories and their structuring with more granularity. Assuming that typography, as a device for visualizing toponyms, is a tool whose potential is still under-exploited, we ask ourselves how the field of typographic design can improve our understanding of toponymic categories and help to structure them in a multi-scale logic. The approach adopted to answer this question is to analyse several existing maps to find good and bad practices. We identified different styles of place names and we built a typology of text features in the surveyed maps. The surveyed maps are the 1 : 35 000 scale, in IGN-France, OSM and GoogleMaps portals.
