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.

[Vedettes matières IGN] CartologieRésumé : (Auteur) This paper describes a study of the evaluation of cartographic quality of urban plans in the Czech Republic using eye-tracking. Although map visualization is a crucial part of the urban planning process, only a few studies have focused on the evaluation of these maps. The plans of four Czech cities with different styles of visualization and legends were used in this eye-tracking experiment. Respondents were required to solve spatial tasks consisting of finding and marking a certain symbol on a map. Statistical analyses of various eye-tracking metrics were used, and the differences between experts and students and between the map and legend sections of the stimuli were explored. The study results showed that the quality of map symbols and the map legend significantly influence the legibility and understandability of urban plans. For correct decision-making, it is essential to produce maps according to certain standards, to make them as clear as possible, and to perform usability testing on them.

[Termes IGN] vingtième siècleRésumé : (Auteur) Although the maps of the Third and Fourth Military Surveys of the Austria–Hungarian Empire were classified, after its dissolution the new countries had access to the topographic maps covering their own territories. Lehmann’s slope hachures were used for representing relief, both at the survey scale and the derived scales. Contour lines were used to plan the hachures, which were the primary method of relief representation; therefore, most of the contour lines were removed from the final map. Following the political and administrative changes, a new organization, the independent Military Mapping Group was established in Hungary in 1919. After developing it into an institute, Hungary started a new topographic survey revising the former Austro-Hungarian 1:25 000 scale topographic maps. The revision changed the relief representation from hachures to contour lines and the language of the map lettering from German to Hungarian.

[Termes IGN] tsunamiRésumé : (auteur) Preventing people exposed to natural hazards is a fundamental lever to reduce their vulnerability and the associated risk. In this context, evacuation maps can be considered as a useful tool to educate populations in order to get an appropriate behavior in case of disaster, and to maintain a culture of the risk in exposed areas. Since the catastrophic events in the Indian Ocean and Japan, local initiatives for the creation of tsunami evacuation maps have developed worldwide. However, no clear recommendations for the elaboration of these maps have already been proposed. This lack concerns the methods and rules used to create and represent the information present in the map. So, this article seeks to provide consensual symbolization rules for tsunami evacuation maps. To achieve this objective, a critical analysis was conducted from a sample of 30 tsunami evacuation maps. As a result, major trends and recurring choices have been extracted and compiled in a proposition for symbolization rules. This proposition, which has been implemented on various sites in the Mediterranean and Caribbean seas, can be seen as a first contribution for the harmonization of tsunami evacuation maps, in order to provide a universal cartographic language for exposed populations.
