Type de document : Article/Communication Auteurs : Dennis Edler, Auteur ; Oliver Huber, Auteur ; Claudia Knust, Auteur ; et al., Auteur Année de publication : 2014 Article en page(s) : pp 153 -163 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] cognition [Termes IGN] couche thématique [Termes IGN] lecture de carte [Termes IGN] représentation cartographique 3D [Vedettes matières IGN] Géovisualisation Résumé : (Auteur) In recent years, True-3D representations such as lenticular visualization have entered the stage of analogue and, especially, digital cartography. The increase of 3D displays as products of mass media raises some fundamental questions about a new generation of 3D maps. Auto-stereoscopic displays allow cartographers to design 3D maps covering several information layers located at different positions along the depth axis. However, it remains unclear whether the opportunity to spread map information over different information depth layers can improve cartographic communication by helping to increase the duration and accuracy of map reading. This article presents the results of an empirical study, based on the test results achieved by 83 geography students who counted different map symbols in a series of 2D or 3D thematic maps of differing complexity.

Principles and terminology of true-3D geovisualisation / Claudia Knust in Cartographic journal (the), vol 51 n° 3 (August 2014)  

Public [article]  inCartographic journal (the) > vol 51 n° 3 (August 2014) . - pp 191 - 202 Titre : Principles and terminology of true-3D geovisualisation Type de document : Article/Communication Auteurs : Claudia Knust, Auteur ; Manfred F.

Hence, one might easily lose track of what 3D means in a particular context. 3D is just a generic term which the authors are trying to classify into different groups. An overview of the technical status of 3D technologies serves to explain the importance of the three-dimensionality in cartography. Solid landscape embodiments as well as pseudo-three-dimensional and truly three-dimensional autostereoscopic visualisations on planar displays are treated. Starting with the reasons for the advantages and the necessities for true-3D representations the article deals with the classification and explanation of the different true-3D visualisation techniques so far materialized for geodata, in particular at the Institute for Cartography of the Dresden University of Technology.

Z-axis based visualization of map elements - cartographic experiences with 3D monitors using lenticular foil technology / Kai Bröhmer in Cartographic journal (the), vol 50 n° 3 (August 2013)  

Public [article]  inCartographic journal (the) > vol 50 n° 3 (August 2013) . - pp 211 - 217 Titre : Z-axis based visualization of map elements - cartographic experiences with 3D monitors using lenticular foil technology Type de document : Article/Communication Auteurs : Kai Bröhmer, Auteur ; Claudia Knust, Auteur ; et al., Auteur Année de publication : 2013 Article en page(s) : pp 211 - 217 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] carte thématique [Termes IGN] cartographie 3D [Termes IGN] données localisées 3D [Termes IGN] visualisation 3D Résumé : (Auteur) The current advent of autostereoscopic monitors and TV screens using lenticular foil technology proves the increasing desire to visualize movies, pictures, graphics or even maps in true-3D. These techniques could expand the cartographic ‘tool box’ drastically, implying that 3D is no longer limited to the well-known representation of landform characteristics. Major map design aspects of multi-image models have been analyzed and evaluated regarding their use in thematic cartography. For map design using lenticular foil technology empirical findings are necessary to position layers adequately along the z-axis of a 3D depiction. Hovering layers may generate additional information values, which seem to be able to compensate the shortcomings in 2D maps. Several parameters or dimensions of cartographic contents can be displayed simultaneously. True-3D display techniques must be implemented in a differentiated manner to achieve positive impacts on cartographic communication. However, lenticular foil technique opens perspectives for more diverse products in thematic cartography.
