Ambiguous use of geographical information systems for the rectification of large-scale geometric maps / Anders Wästfelt in Cartographic journal (the), Vol 57 n° 3 (August 2020)  

Public [article]  inCartographic journal (the) > Vol 57 n° 3 (August 2020) . - pp 209 - 220 Titre : Ambiguous use of geographical information systems for the rectification of large-scale geometric maps Type de document : Article/Communication Auteurs : Anders Wästfelt, Auteur Année de publication : 2020 Article en page(s) : pp 209 - 220 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Applications SIG [Termes IGN] ArcGIS [Termes IGN] carte ancienne [Termes IGN] correction géométrique [Termes IGN] déformation de projection [Termes IGN] déformation géométrique [Termes IGN] erreur de mesure [Termes IGN] erreur géométrique [Termes IGN] grande échelle [Termes IGN] grille [Termes IGN] point [Termes IGN] qualité des données [Termes IGN] Suède [Termes IGN] système de coordonnées Résumé : (auteur) Unlike modern maps, geometric maps lack a coordinate system and contain unsystematic geometric inaccuracies. This paper illuminates four aspects concerning the problem of uniting geographical information technology with old geometric maps. These are as follows: first, the origin of and geometric qualities in the representation of objects in geometric maps; second, the distortions originating from measurement techniques; third, the assumption that it is possible to find points that are the same over time for rectification in Geographic Information System (GIS); and, fourth, the extrapolation of unsystematic geometric distortions when using GIS techniques without any knowledge of the present unsystematic distortions in a map. The article presents the background of Swedish geometric maps and a hypothetical example is used to present the principle problems of using GIS techniques to rectify geometric maps. The conclusion of the paper is that systematic and unsystematic geometric distortions need to be identified and handled separately.

The influence of web maps and education on adolescents’ global-scale cognitive map / Lieselot Lapon in Cartographic journal (the), Vol 57 n° 3 (August 2020)  

Public [article]  inCartographic journal (the) > Vol 57 n° 3 (August 2020) . - pp 221 - 234 Titre : The influence of web maps and education on adolescents’ global-scale cognitive map Type de document : Article/Communication Auteurs : Lieselot Lapon, Auteur ; Philippe De Maeyer, Auteur ; Bart De Wit, Auteur ; et al., Auteur Année de publication : 2020 Article en page(s) : pp 221 - 234 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] acquisition de connaissances [Termes IGN] carte cognitive [Termes IGN] cartographie par internet [Termes IGN] déformation de projection [Termes IGN] formation [Termes IGN] lecture de carte [Termes IGN] projection [Termes IGN] projection de Robinson [Termes IGN] projection Universal Transverse Mercator [Termes IGN] web mapping [Vedettes matières IGN] Cartologie Résumé : (auteur) Several factors influence the global-scale cognitive map. The use of school books, atlases and web maps all play an essential role in the development of geographical knowledge of adolescents. This research examines the impact of the educational system versus web maps on the adolescents’ mental map. Through a specially designed web application, university students and secondary school pupils estimated the real proportion of countries and continents compared to Europe. Participants with a more theoretical background or wider knowledge about map projections and its distortions estimated the real proportions more accurately. This research also found that the Robinson projection, commonly used in schoolbooks and atlases, is the best-known map projection among adolescents. However, the influence of web maps could not be proven since no Mercator effect was found. Education is of undeniable importance, and therefore, educational materials that encourage people to look more carefully and critically at maps should be further developed.

Emplaced distances / Giovanni Spissu in Cartographic journal (the), Vol 57 n° 3 (August 2020)  

Public [article]  inCartographic journal (the) > Vol 57 n° 3 (August 2020) . - pp 261 - 272 Titre : Emplaced distances Type de document : Article/Communication Auteurs : Giovanni Spissu, Auteur Année de publication : 2020 Article en page(s) : pp 261 - 272 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Rédaction cartographique [Termes IGN] art [Termes IGN] Cape Town [Termes IGN] carte profonde [Termes IGN] esthétique [Termes IGN] ethnographie [Termes IGN] représentation cartographique [Termes IGN] Sardaigne [Termes IGN] territoire Résumé : (auteur) In the Sardinian artist’s Maria Lai’s works, Geografie and Geogafie Spaziali, she depicted the cosmic pathways of the Sardus Pater, using a cartographic representation of one of the island’s most popular legends. One of these works’ key features is the use of embroidery techniques learned from women of her village. She considers the Sardinian territory not only an object of representation but as an expressive medium of her work and a fertile space that generates new worlds. I argue that we can draw on Maria Lai’s work to conceive a particular form of deep mapping through which to explore the territory through its imaginative dimension. For the purpose of this article, I intend to describe how, inspired by Lai’s works, I built Emplaced Distance, a map of Cape Town through the Sardinian territory.

Breaking the eyes: how do users get started with a coordinated and multiple view geovisualization tool? / Izabela Golebiowska in Cartographic journal (the), Vol 57 n° 3 (August 2020)  

Public [article]  inCartographic journal (the) > Vol 57 n° 3 (August 2020) . - pp 235 - 248 Titre : Breaking the eyes: how do users get started with a coordinated and multiple view geovisualization tool? Type de document : Article/Communication Auteurs : Izabela Golebiowska, Auteur ; Tomasz Opach, Auteur ; Jan Ketil Rød, Auteur Année de publication : 2020 Article en page(s) : pp 235 - 248 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] analyse géovisuelle [Termes IGN] comportement [Termes IGN] exploration de données géographiques [Termes IGN] interactivité [Termes IGN] oculométrie [Termes IGN] utilisateur [Termes IGN] zone d'intérêt [Vedettes matières IGN] Géovisualisation Résumé : (auteur) Maps are frequently combined with data displays in the form of coordinated and multiple views (CMV). Although CMV are valuable geovisualization tools, novice users may find them complex and thus require explanation. However, no tutorial guidelines have been developed that indicate what is helpful in understanding CMV geovisualization tools. We therefore conducted a study on the learnability of a CMV tool, informed with eye-tracking data, talk-aloud and interaction logs. We have investigated how untrained users work with a CMV geovisualization tool. The study revealed that: (1) despite their initial confusion, users found the tested tool pleasant to play with while getting to grips with how dynamic brushing works, (2) when examining the tool’s interface, participants mainly looked freely at explanatory elements, such as labels and the legend, but they explored interactive techniques only to a limited degree. We conclude with tips about tutorial design and layout design for CMV tools.
