This paper explores the role of news maps in geopolitical discourse with reference to the potential super-power status of key states, specifically China and Russia as members of the BRIC group (Brazil, Russia, India and China), and in the case of Russia, the NORCs (Northern Rim Countries – Canada, Russia, several Scandinavian states and the USA). It also explores references to ‘threats’ to a stable interstate system (resource wars, regional instability, ‘rouge states’). The paper argues that the concept of the state as ‘power container’ provides a key to understanding how maps operate as a significant element within geopolitical discourse. Maps provide spatial and geostrategic context to the narratives being deployed by news providers on such matters as China’s projection of power. The paper is based on the findings of a comprehensive survey of maps in the UK ‘quality press’ in 2009.

Landscape preference and map readability in design evaluation of topographic maps with an orthoimage background / Paulo Raposo in Cartographic journal (the), vol 51 n° 1 (February 2014)  

Public [article]  inCartographic journal (the) > vol 51 n° 1 (February 2014) . - pp 25 - 37 Titre : Landscape preference and map readability in design evaluation of topographic maps with an orthoimage background Type de document : Article/Communication Auteurs : Paulo Raposo, Auteur ; Cynthia A. Brewer, Auteur Année de publication : 2014 Article en page(s) : pp 25 - 37 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie [Termes IGN] carte topographique [Termes IGN] conception cartographique [Termes IGN] estompage [Termes IGN] lisibilité perceptive [Termes IGN] orthoimage [Termes IGN] réalité augmentée Résumé : (Auteur) Orthoimagery and shaded relief are ways of introducing realism to maps, but each method presents design challenges in achieving consistently readable combinations with overlaid vector symbols and labels. Two studies were conducted to compare the readability of the current United States Geological Survey (USGS) ‘US Topo’ map series with two original designs incorporating orthoimagery and shaded relief. The studies examined reader design ratings after completing tasks that required analytical use of maps with varied map designs, using maps of diverse locations in the USA. The studies indicated that readability varied with map location to a greater degree than with map design, though design influence on ratings was detected in interaction with location. This variation with landscape is discussed from the perspective of recent theory in landscape aesthetics and preferences. Also, it was statistically demonstrated that either of the two new designs had improved readability over the existing US Topo. These studies reveal that user evaluations of maps are dependent on landscape preferences as well as on design, and demonstrate the importance of national topographic map design evaluation across a wide sample of national landscapes.

Use of artificial neural networks for selective omission in updating road networks / Qi Zhou in Cartographic journal (the), vol 51 n° 1 (February 2014)  

Public [article]  inCartographic journal (the) > vol 51 n° 1 (February 2014) . - pp 38 - 51 Titre : Use of artificial neural networks for selective omission in updating road networks Type de document : Article/Communication Auteurs : Qi Zhou, Auteur ; Zhilin Li, Auteur Année de publication : 2014 Article en page(s) : pp 38 - 51 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Bases de données localisées [Termes IGN] analyse comparative [Termes IGN] carte de Kohonen [Termes IGN] généralisation cartographique automatisée [Termes IGN] mise à jour automatique [Termes IGN] mise à jour cartographique [Termes IGN] réseau neuronal artificiel [Termes IGN] réseau routier Résumé : (Auteur) An important problem faced by national mapping agencies is frequent map updates. An ideal solution is only updating the large-scale map with other smaller scale maps undergoing automatic updates. This process may involve a series of operators, among which selective omission has received much attention. This study focuses on selective omission in a road network, and the use of an artificial neural network (i.e. a back propagation neural network, BPNN). The use of another type of artificial neural network (i.e. a self-organizing map, SOM) is investigated as a comparison. The use of both neural networks for selective omission is tested on a real-life road network. The use of a BPNN for practical application road updating is also tested. The results of selective omission are evaluated by overall accuracy. It is found that (1) the use of a BPNN can adaptively determine which and how many roads are to be retained at a specific scale, with an overall accuracy above 80%; (2) it may be hard to determine which and how many roads should be retained at a specific scale using an SOM. Therefore, the BPNN is more effective for selective omission in road updating.

Morphometric mapping of topography by flowline hachures / Timofey Samsonov in Cartographic journal (the), vol 51 n° 1 (February 2014)  

Public [article]  inCartographic journal (the) > vol 51 n° 1 (February 2014) . - pp 63 - 74 Titre : Morphometric mapping of topography by flowline hachures Type de document : Article/Communication Auteurs : Timofey Samsonov, Auteur Année de publication : 2014 Article en page(s) : pp 63 - 74 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Rédaction cartographique [Termes IGN] automatisation [Termes IGN] géomorphométrie [Termes IGN] hachure [Termes IGN] rédaction cartographique [Termes IGN] représentation du relief Résumé : (Auteur) Hachuring is a classic method of cartographic relief presentation that origins from perspective sketching of the surface. Hachuring was developed into strict and mathematically grounded planimetric method during the eighteenth century. Established by Lehmann in 1799, topographic hachures flourished during the first half of the nineteenth century and then were gradually replaced by contours. Today, hachures are still popular in presentation of anthropogenic relief on archaeological and topographic maps. Some elements of hachuring can be found in geomorphometric and hydrometeorological mapping, where flowlines and arrows are used to show the intensity and direction of the flow on the surface, or its aspect and slope. The study aims to reveal the potential of hachuring in further development as surface presentation method. Automated implementation of all original requirements for hachure construction is provided for the first time by new algorithm using vector flowlines. Then an advanced hachuring technique called ‘slope and aspect hachuring’ is presented which depicts slope, aspect and flow direction of the surface simultaneously. Slope and aspect hachuring is compared to traditional area colours to reveal its advantages and shortcomings in sight of morphometric mapping. Some applications of the method and directions of future research are suggested in concluding part.

Evaluating the efficiency of typographic design: Gender and expertise variation / Rasha Deeh in Cartographic journal (the), vol 51 n° 1 (February 2014)  

Public [article]  inCartographic journal (the) > vol 51 n° 1 (February 2014) . - pp 75 - 86 Titre : Evaluating the efficiency of typographic design: Gender and expertise variation Type de document : Article/Communication Auteurs : Rasha Deeh, Auteur ; Kristien Ooms, Auteur ; Valérie Vanopbrocke, Auteur ; Philippe De Maeyer, Auteur Année de publication : 2014 Article en page(s) : pp 75 - 86 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Rédaction cartographique [Termes IGN] écriture cartographique [Termes IGN] lisibilité perceptive [Termes IGN] placement automatique des écritures Résumé : (Auteur) Although the efficiency of label placement algorithms has been studied extensively, few studies considered the influence of the label designs on the efficiency of map readers. Labels are one of the most important elements on the map as they can provide more information than other symbols can. The design of the labels does have to stress the theme, shape and functionality of the associated objects, which results in a more efficient interpretation of the map content by the user. How the label designs can enhance the map readers’ efficiency (and thus the quality of the maps themselves) is the main objective of this study. A user study was conducted in which the participants were asked to locate a target label on a map. Different label designs were implemented across the trials. The participants’ reactions times were registered to measure their efficiency and statistically analysed using a one-way ANOVA. Two different users’ characteristics were considered: gender and expertise. Related to the size, shape, orientation and texture of the labels, a number of significant differences (P Numéro de notice : A2014-130 Affiliation des auteurs : non IGN Thématique : GEOMATIQUE Nature : Article nature-HAL : ArtAvecCL-RevueIntern DOI : 10.1179/1743277413Y.0000000037 En ligne : https://doi.org/10.1179/1743277413Y.0000000037 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=33035 [article]
