A ‘devious course’ : projecting toleration on Mercator’s ‘map of the world’, 1569 / J. Brotton in Cartographic journal (the), vol 49 n° 2 (May 2012)

This paper argues that by resituating Mercator's career within the theological conflicts of the European Reformation, it is possible to identify a more moralised, stoic inspiration for the projection's creation. In particular, Mercator's preceding work on theology and chronology disclose other ways of interpreting the projection. The rhumb line is taken as a defining element of Mercator's theological geography.

Digital representation of historical globes : methods to make 3D and pseudo-3D models of sixteenth century Mercator globes / Cornelis Stal in Cartographic journal (the), vol 49 n° 2 (May 2012)  

Public [article]  inCartographic journal (the) > vol 49 n° 2 (May 2012) . - pp 107 - 117 Titre : Digital representation of historical globes : methods to make 3D and pseudo-3D models of sixteenth century Mercator globes Type de document : Article/Communication Auteurs : Cornelis Stal, Auteur ; De Wulf, Auteur ; et al., Auteur Année de publication : 2012 Article en page(s) : pp 107 - 117 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Applications photogrammétriques [Termes IGN] acquisition d'images [Termes IGN] données lidar [Termes IGN] données localisées 3D [Termes IGN] géoréférencement [Termes IGN] globe [Termes IGN] image terrestre [Termes IGN] lasergrammétrie [Termes IGN] objet géographique 3D [Termes IGN] patrimoine culturel [Termes IGN] reconstruction d'objet [Termes IGN] texturage [Termes IGN] traitement d'image Résumé : (Auteur) In this paper, the construction of digital representations of a terrestrial and celestial globe will be discussed. Virtual digital (3D) models play an important role in recent research and publications on cultural heritage. The globes discussed in this paper were made by Gerardus Mercator (1512-1594) in 1541 and 1551. Four techniques for the digital representation are discussed and analysed, all using high-resolution photographs of the globes. These photographs were taken under studio conditions in order to get equal lighting and to avoid unwanted light spots. These lighting conditions are important, since the globes have a highly reflective varnish covering. Processing these images using structure from motion, georeferencing of separate scenes and the combination of the photographs with terrestrial laser scanning data results in true 3D representations of the globes. Besides, pseudo-3D models of these globes were generated using dynamic imaging, which is an extensively used technique for visualisations over the Internet. The four techniques and the consequent results are compared on geometric and radiometric quality, with a special focus on their usefulness for distribution and visualisation during an exhibition in honour of the five hundredth birthday of Gerardus Mercator.

Automatic symbolisation methods for geoportals / Ara Toomanian in Cartographic journal (the), vol 49 n° 2 (May 2012)

From a technical viewpoint, web services and geoportals aim to fulfil user requirements; however, the current cartographic methods do not satisfy the needs of the end users. The problem is more challenging when the final map contains data from various sources that have various cartographic characteristics; therefore, the vital information might be located under the base map layer. In this paper, we propose the concept of layer priorities as foreground, middle ground or background, and we propose the two following methods to enhance the symbolisation: polygon overlay and colour saturation methods. The results from two case studies show that these methods can satisfy the requirements of the end users.

Typography in the eyes of Bertin, gender and expertise variation / R. Deeb in Cartographic journal (the), vol 49 n° 2 (May 2012)  

Public [article]  inCartographic journal (the) > vol 49 n° 2 (May 2012) . - pp 176 - 185 Titre : Typography in the eyes of Bertin, gender and expertise variation Type de document : Article/Communication Auteurs : R. Deeb, Auteur ; Kristien Ooms, Auteur ; Philippe De Maeyer, Auteur Année de publication : 2012 Article en page(s) : pp 176 - 185 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Rédaction cartographique [Termes IGN] sémiologie graphique [Termes IGN] typographie Résumé : (Auteur) The main goal of this research is to set a group of typographic criteria to suit a wide array of map users. A group of Bertin’s visual variables were applied individually and associatively for the same set of labels. Two kinds of maps (with point and areal objects) were presented to expert and non-expert map users and analysed accordingly. Additionally, the effect of gender variation was taken into account. The data were aggregated and studied for each graphical variable. For some combinations of Bertin’s variables, statistically significant differences were detected in the preferences of the different map users (e.g. male versus female and expert versus non-expert). Consequently, we identified which graphical variables (individually or combined) were more preferred by specific user groups in relation to their application on text objects.
