[Termes IGN] visualisation 3DRésumé : (Auteur) A novel method called multidirectional visibility index (MVI) has been developed and verified. The MVI improves standard cartographic analytical shading with a number of enhancements to topographic detail and prominent structures, i.e. the portrayal of flat areas in lighter tones, the accentuation of morphologic edges, and the multiscale visualisation of morphologic terrain features. The procedure requires a digital elevation model (DEM) and involves the following steps: visibility mask computation; the respective multidirectional altering of the azimuth and elevation angle; the generation of continuous grid MVIs that indicate upper/lower views, quasi-slope, and relative relief; and an appropriate visualisation of the relevant MVI as a standalone technique or in combination with standard hill-shaded relief. The modelling parameters are robust and therefore highly adaptive to different landforms.

[Termes IGN] visualisation de donnéesRésumé : (Auteur) With the development of geographic information science and the progress in the research of scientific visualisation, the visualisation of multivariate geospatial data has attracted much attention. This paper discusses an IconMap-based visualisation technique that enables multiple geospatial variables be represented in a single raster layer. This is achieved by extending the conventional pixel-based image structure to the three-tiered iconic design. Thereby the spatial pattern generated by the interaction between multivariate geographic variables can be disclosed, and the goal of geospatial data mining is achieved. A visualisation case study on soil organic matter and nutrients for the Shuangliu County of Chengdu City, China, was performed using the proposed approach. The result shows that the static IconMap can better display the distribution tendency of the high-end and low-end soil organic matter and nutrients, and that the dynamic IconMap can both reflect the interaction between the organic matter and the nutrients variables, and display the soil fertility levels in a comprehensive way. Thus, the IconMap-based visualisation approach is a non-fused, exploratory analytical approach for multivariate data and valuable for visually analyse the soil fertility condition.

[Termes IGN] symbole graphiqueRésumé : (Auteur) This study uses cartometric techniques to reveal cartographic design considerations operative in Frank H. Galbraith’s 1897 railway mail service training maps. Galbraith’s maps make extensive use of humorous cartouches intended to serve as mnemonic devices for learning railway mail service routes. Poisson and quadrat point pattern analyses are performed on all eight maps in the series to determine whether the mimetic symbols are clustered along the railway mail routes or dispersed throughout the mapped spaces to achieve better graphic balance. Evidence overwhelmingly indicates that the placement of the mnemonic symbols was primarily driven by design considerations. The study therefore proves that it is possible to use cartometric techniques to deconstruct the map document to determine the cartographic design principles operative during the map's construction.

[Termes IGN] utilisateurRésumé : (Auteur) This paper focuses on improving the efficiency and effectiveness of dynamic and interactive maps in relation to the user. A label placement method with an improved algorithmic efficiency is presented. Since this algorithm has an influence on the actual placement of the name labels on the map, it is tested if this efficient algorithms also creates more effective maps: how well is the information processed by the user. We tested 30 participants while they were working on a dynamic and interactive map display. Their task was to locate geographical names on each of the presented maps. Their eye movements were registered together with the time at which a given label was found. The gathered data reveal no difference in the user’s response times, neither in the number and the duration of the fixations between both map designs. The results of this study show that the efficiency of label placement algorithms can be improved without disturbing the user’s cognitive map. Consequently, we created a more efficient map without affecting its effectiveness towards the user.

However, a lot of people are not aware where administrative boundaries lie, limiting their appeal for educating the public on important issues such as poverty and inequality. This paper seeks to utilize a well-known cartographic map design, the London Underground map, to aid data dissemination of the complex issues surrounding inequality and deprivation in London. A discussion of the relevance of this approach to researching inequality in London, as well as how this fits in with previous approaches to mapping poverty is provided. An example using the recent release of the Indices of Multiple Deprivation 2010 shows the usefulness of this design.

[Termes IGN] populationRésumé : (Auteur) Paying the tribute to the 100 years anniversary of dasymetric mapping, this paper aims to provide a detailed inquiry into historical beginnings of this cartographic technique by working with literature and archival sources, primarily with the writings of the method’s inventor, Benjamin Semenov-Tian-Shansky. The paper confirms that the dasymetric method was first proposed in 1911 and its first cartographic products appeared in 1919. The paper reviews and discusses the dasymetric technique used by Semenov-Tian-Shansky in the 1920s to produce the ‘Dasymetric Map of European Russia’ that, perhaps, still remains one of the most extensive dasymetric mapping projects in the history of cartography. This research will help to continue reconstructing the history of dasymetric mapping and will aid in better understanding of the original technique itself and its relations with later achievements in cartography and GIScience.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) Rough set and fuzzy set are two frequently used approaches for modelling and reasoning about imperfect time intervals. In this paper, we focus on imperfect time intervals that can be modelled by rough sets and use an innovative graphic model [i.e. the triangular model (TM)] to represent this kind of imperfect time intervals. This work shows that TM is potentially advantageous in visualizing and querying imperfect time intervals, and its analytical power can be better exploited when it is implemented in a computer application with graphical user interfaces and interactive functions. Moreover, a probabilistic framework is proposed to handle the uncertainty issues in temporal queries. We use a case study to illustrate how the unique insights gained by TM can assist a geographical information system for exploratory spatio-temporal analysis.
