[Termes IGN] toponymeRésumé : (auteur) Geoinformationis represented in increasing numbers of different forms, with heterogeneous social and cultural implications. This paper highlights the merits as well as the ambivalence of the social (especially) and political effects of the widespread expansion and growing importance of (volunteered) geographic information. This general overview of the basic symbolic forms in which geoinformation appears distinguishes between three areas of spatial semantics: while technological systems address space mainly in numerical terms, the user refers to space by ego-centered deixis, while society and culture provide the established everyday language of toponyms. The main argument, based on this categorization, stresses the importance of diversity and transparency in acting and interacting with geoinformation and geomedia in order to promote empowerment, education and reflection.

Given the number of mapping methods used in thematic cartography, the question arises of what extent the utilized method influences a user’s map use level. For this reason, research has been undertaken with 392 students in the 17–20 age group with the aim of identifying and clarifying the influence of the mapping methods used (specifically choropleth mapping, diagram mapping, qualitative and quantitative line symbols, and area shading). The results have shown that the students were less successful with maps that used quantitative mapping methods than with maps using qualitative or both qualitative and quantitative mapping methods. The differences were most significant in the case of the cognitively demanding map interpretation skill, especially due to the students’ problematic understanding of the very essence of the quantitative methods. The different natures of the tested mapping methods also probably accounted for the identification of various factors explaining the differences in the levels of the work with the given thematic maps among the individual tested students.

[Termes IGN] représentation cartographiqueRésumé : (Auteur) Colour distortion, which is caused by the unavoidable mismatch between a map’s gamut and a device’s gamut, negatively affects the semiotic quality of maps. Cartographic communication often suffers from undesirable colour inconsistency. This method models cartographic colour reproduction as a constrained transform problem, namely, adapting a map’s gamut to fit a device’s gamut while preserving the semiotic quality. First, the characteristics of the map’s gamut are investigated by considering cartographic principles, and the fundamental concerns of preserving semiotic quality are proposed. Then, the self-organizing map method is introduced to iteratively optimize the cartographic colour reproduction. We implement this method and evaluate it based on a series of thematic maps. The results indicate that the proposed algorithm offers better results than two alternatives in terms of facilitating cartographic colour reproduction.

[Termes IGN] variable visuelleRésumé : (Auteur) Glyphs are small geometric shapes that in geovisualization are often used to represent multidimensional spatial data. The aim of this study is to investigate the effectiveness of their two types – star and polyline glyphs, as they can encode the same message and can provide similar functionality. Thus, if the two glyph types are similar and can be used for the same data, the question arises as to which of them better facilitates various user tasks. To address this question, an empirical study of 26 individual users is conducted to investigate differences in user performance for polyline and star glyphs shown either in a grid plot or on a map display. In this study, a task-based approach with eye-tracking is applied, as well as a subjective questionnaire and a psychological test of cognitive style. The finding is that polyline glyphs better facilitate tasks when datapoint values in glyphs are to be read, whereas star glyphs are better when a visual search among glyphs is to be done. Moreover, the results reveal that the map display works better than the grid plot. If star glyphs are to be used, the key (legend) needs to be better incorporated into a visual interface.

[Termes IGN] températureRésumé : (Auteur) Climate maps have been widely used for the construction of species distribution models. These maps derive from interpolation of data collected by meteorological stations. The sparse distribution of stations generates maps with coarse spatial resolution that are unable to detect microclimates or areas that can serve as plant or animal refuges. This work proposes a method for downscaling temperature maps using the solar radiation falling upon hillsides as predictor for the influence of relief on local variability. Solar irradiance is estimated from a digital elevation model of the study area using a routine based on analytical hillshading. Some examples of downscaling from 1 km to 25 m spatial resolution are shown. The results are compared with the surface temperature maps from Landsat 8 satellite imagery.
