A design pattern approach to cartography with big geospatial data / Serena Coetzee in Cartographic journal (the), Vol 54 n° 4 (November 2017)  

Public [article]  inCartographic journal (the) > Vol 54 n° 4 (November 2017) . - pp 301 - 312 Titre : A design pattern approach to cartography with big geospatial data Type de document : Article/Communication Auteurs : Serena Coetzee, Auteur ; Victoria Rautenbach, Auteur Année de publication : 2017 Article en page(s) : pp 301 - 312 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] conception cartographique [Termes IGN] données localisées [Termes IGN] données massives [Termes IGN] modèle cartographique [Vedettes matières IGN] Géovisualisation Résumé : (Auteur) A design pattern approach for conceptualizing the cartographic design process is presented. A design pattern presents a solution to a problem by describing solutions for the commonalities in problems to be solved. The commonalities of the cartographic design process are identified and MapDesign is described, a design pattern for generating a set of maps from big geospatial data. The MapDesign pattern allows increased map throughput through automation and distributed processing, which frees up time for cartographers and geographic information scientists to make sense of big geospatial data and to select and refine map designs. The description of the MapDesign pattern can aid software developers in understanding how to build tools that allow automation and distributed processing in parts of the map design process for visualizing big geospatial data. Conversely, the visual nature of design patterns can assist cartographers with understanding how software components interact to produce maps.

Augmented reality and maps : new possibilities for engaging with geographic data / Gabriel Henrique de Almeida Pereira in Cartographic journal (the), Vol 54 n° 4 (November 2017)  

Public [article]  inCartographic journal (the) > Vol 54 n° 4 (November 2017) . - pp 313 - 321 Titre : Augmented reality and maps : new possibilities for engaging with geographic data Type de document : Article/Communication Auteurs : Gabriel Henrique de Almeida Pereira, Auteur ; Kristin Stock, Auteur ; Lucienne Stamato Delazari, Auteur ; Jorge Antonio Silva Centeno, Auteur Année de publication : 2017 Article en page(s) : pp 313 - 321 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] données localisées [Termes IGN] lecture de carte [Termes IGN] Nouvelle-Zélande [Termes IGN] programme interactif [Termes IGN] réalité augmentée [Termes IGN] utilisateur civil [Vedettes matières IGN] Cartologie Résumé : (Auteur) Among the systems that aim to help users to perform map reading tasks, augmented reality (AR) is one of the most promising. However, the impact of this new technology in terms of acceptance, motivation and improvement of the learning process has still not been sufficiently explored. This study aims to assess the contribution of an AR system for map reading and for improving users’ understanding of geographic data. Landscape and census data from New Zealand were used to evaluate the performance of an AR system in an experiment involving 60 participants. Differences in the participants’ backgrounds were reflected in the way they completed the task for both printed maps and the AR system and 90% of the participants preferred to work with the AR system rather than with traditional printed maps. Users that had previous experience of the geographical dataset provided performed the task better using only the printed maps, while those without that experience performed better with the AR system.

Experiments to distribute and parallelize map generalization processes / Guillaume Touya in Cartographic journal (the), Vol 54 n° 4 (November 2017)  

Public [article]  inCartographic journal (the) > Vol 54 n° 4 (November 2017) . - pp 322 - 332 Titre : Experiments to distribute and parallelize map generalization processes Type de document : Article/Communication Auteurs : Guillaume Touya , Auteur ; Justin Berli , Auteur ; Imran Lokhat , Auteur ; Nicolas Regnauld , Auteur Année de publication : 2017 Projets : 1-Pas de projet / Article en page(s) : pp 322 - 332 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] partitionnement [Termes IGN] traitement parallèle [Termes IGN] traitement réparti [Vedettes matières IGN] Généralisation Résumé : (Auteur) Automatic map generalization requires the use of computationally intensive processes often unable to deal with large datasets. Distributing the generalization process is the only way to make them scalable and usable in practice. But map generalization is a highly contextual process, and the surroundings of a generalized map feature needs to be known to generalize the feature, which is a problem as distribution might partition the dataset and parallelize the processing of each part. This paper proposes experiments to evaluate the past propositions to distribute map generalization, and to identify the main remaining issues. The past propositions to distribute map generalization are first discussed, and then the experiment hypotheses and apparatus are described. The experiments confirmed that regular partitioning was the quickest strategy, but less effective when taking context into account. The geographical partitioning, though less effective for now, is quite promising regarding the quality of the results as it better integrates the geographical context.

Cartographies of fuzziness : mapping places and emotions / Alenka Poplin in Cartographic journal (the), Vol 54 n° 4 (November 2017)  

Public [article]  inCartographic journal (the) > Vol 54 n° 4 (November 2017) . - pp 291 - 300 Titre : Cartographies of fuzziness : mapping places and emotions Type de document : Article/Communication Auteurs : Alenka Poplin, Auteur Année de publication : 2017 Article en page(s) : pp 291 - 300 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie thématique [Termes IGN] Allemagne [Termes IGN] culture [Termes IGN] émotion [Termes IGN] Etats-Unis [Termes IGN] sciences humaines Résumé : (Auteur) Mapping emotions and places is an emerging field in cartography. This article explores expressed emotions related to power places, which are defined as places at which people can recharge and relax. At these places they can find their balance and inner power. Our research is based on empirical experiments in Germany and the USA in which the participants self-identified and mapped their power places. They described them and selected expressions for emotions that best describe how they feel at these places. The main goal of this paper is to compare the results gained on two different continents. Using Russell's Circumplex Model of Affect, we explore the cultural differences by mapping emotions in a two-dimensional circular place. We conclude the article with a discussion of the results and further research directions.
