This work explores how these failings in the quality of input data may affect the results of global space-time interaction tests. While previous work has partially investigated the impact of locational inaccuracy on the results of these tests, more work remains. The impacts of temporal inaccuracy and incomplete data reporting on the results of these tests remain completely unexplored. This study examines the influence of these problems individually and collectively, using a series of simulations. Findings demonstrate that even in cases of slight inaccuracy or underreporting, the consequences on results are potentially severe. Although the study is couched in terms of data inaccuracy, its relevance to situations where inaccuracy is replaced with uncertainty is self-evident.

[Termes IGN] visualisation 3DRésumé : (Auteur) Landscape is gradually being considered an essential resource and, therefore, is a variable to be included in land planning and protection designations. A structured method of landscape assessment, which links descriptions, classification, analysis, and evaluation, will provide an integrated framework within which the problem of scenic impact from renewable energy sources can be debated and solved. Perceptual qualitative and quantitative data – such as road networks, land cover, satellite imagery, and aerial photography – can be used for site description and analysis or for 3D modeling and GIS-based visualization work. The case study in which our method was applied demonstrates the impact of wind turbines and wind farms, as well as their cumulative effects in Sierra de Pela (Soria and Guadalajara, Spain).

[Termes IGN] zone à risqueRésumé : (Auteur) Dracunculus medinesis is a waterborne parasite that has afflicted human populations for millennia. It is spread to new water bodies by the travel activities of the humans it affects. This study analyzes the relationship between Guinea worm incidence and its proximity to features of the built and natural environment to identify any apparent relationships. The study examines the Tillabéri region in the country Niger where there was a reemergence in the number of cases of Guinea worm in 2003. It is found that population centers with Guinea worm infected individuals are often within two kilometers of nomadic herding routes.

[Termes IGN] visualisation cartographiqueRésumé : (Auteur) This article presents an overview and initial results of a geoweb analysis designed to provide the foundation for a continued discussion of the potential impacts of ‘big data’ for the practice of critical human geography. While Haklay's (2012) observation that social media content is generated by a small number of ‘outliers’ is correct, we explore alternative methods and conceptual frameworks that might allow for one to overcome the limitations of previous analyses of user-generated geographic information. Though more illustrative than explanatory, the results of our analysis suggest a cautious approach toward the use of the geoweb and big data that are as mindful of their shortcomings as their potential. More specifically, we propose five extensions to the typical practice of mapping georeferenced data that we call going ‘beyond the geotag’: (1) going beyond social media that is explicitly geographic; (2) going beyond spatialities of the ‘here and now’; (3) going beyond the proximate; (4) going beyond the human to data produced by bots and automated systems, and (5) going beyond the geoweb itself, by leveraging these sources against ancillary data, such as news reports and census data. We see these extensions of existing methodologies as providing the potential for overcoming existing limitations on the analysis of the geoweb. The principal case study focuses on the widely reported riots following the University of Kentucky men's basketball team's victory in the 2012 NCAA championship and its manifestation within the geoweb. Drawing upon a database of archived Twitter activity – including all geotagged tweets since December 2011–we analyze the geography of tweets that used a specific hashtag (#LexingtonPoliceScanner) in order to demonstrate the potential application of our methodological and conceptual program. By tracking the social, spatial, and temporal diffusion of this hashtag, we show how large databases of such spatially referenced internet content can be used in a more systematic way for critical social and spatial analysis.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) The large-scale (more than 25MW) development of wind energy seems to be a very promising option given climate change and the need to diversify sources of energy. However, in Quebec, Canada, this fast growing field is raising the concern and apprehension of the population for various reasons, the first one being the protection of Quebec’s rural landscape, an important tourism resource. Transparency and participation in the decision-making process are the two major requests of local stakeholders regarding the installation of wind farms. Hence, two methods are essential to address these demands: Multi-Criteria Decision Analysis (MCDA) and Geographic Information Systems (GIS). Several scholars working in different fields, including the wind sector, have used the MCDA-GIS coupling. Therefore, we developed an approach that uses both methods specifically in the context of large-scale wind energy projects. We emphasize how such a approach can be used in the analysis of different scenarios and consider the opinions and attitudes of all stakeholders in order to choose the “best” one based on a participative, transparent decision making process.
