[Termes IGN] visualisation dynamiqueRésumé : (Auteur) This article reports on the applied research behind a geospatial mobile augmented reality system that can run in situ simulations of dynamic spatial phenomena. The authors summarize previous work that has led to a critical convergence of enabling technologies and identify new forms of geovisualization facilitated by these technologies. The article introduces situated simulation as a new form of augmented situated geovisual analysis, using two versions of a prototype system called A Touch of Rain. This system allows users to run augmented precipitation simulations in real space, in which virtual rain falls on and interacts with real landscapes and buildings, and thus to perform augmented geovisual analysis. This method opens up new opportunities to link geospatial data, models, and everyday spaces. The authors conclude by discussing implications and opportunities for GIScience.

[Vedettes matières IGN] GéovisualisationRésumé : (auteur) Mining a large origin–destination dataset of journeys made through London’s Cycle Hire Scheme (LCHS), we develop a technique for automatically classifying commuting behaviour that involves a spatial analysis of cyclists’ journeys. We identify a subset of potential commuting cyclists, and for each individual define a plausible geographic area representing their workplace. All peak-time journeys terminating within the vicinity of this derived workplace in the morning, and originating from this derived workplace in the evening, we label commutes. Three techniques for creating these workplace areas are compared using visual analytics: a weighted mean-centres calculation, spatial k-means clustering and a kernel density-estimation method. Evaluating these techniques at the individual cyclist level, we find that commuters’ peak-time journeys are more spatially diverse than might be expected, and that for a significant portion of commuters there appears to be more than one plausible spatial workplace area. Evaluating the three techniques visually, we select the density-estimation as our preferred method. Two distinct types of commuting activity are identified: those taken by LCHS customers living outside of London, who make highly regular commuting journeys at London’s major rail hubs; and more varied commuting behaviours by those living very close to a bike-share docking station. We find evidence of many interpeak journeys around London’s universities apparently being taken as part of cyclists’ working day. Imbalances in the number of morning commutes to, and evening commutes from, derived workplaces are also found, which might relate to local availability of bikes. Significant decisions around our workplace analysis, and particularly these broader insights into commuting behaviours, are discovered through exploring this analysis visually. The visual analysis approach described in the paper is effective in enabling a research team with varying levels of analysis experience to participate in this research. We suggest that such an approach is of relevance to many applied research contexts.

[Termes IGN] visualisation cartographiqueRésumé : (Auteur) Analysis of eye movements has been used for decades as a method for assessing the performance of visual stimuli. Until recently, this has mainly been applied to static and non-cartographic stimuli, but due to technological developments and reduced cost of equipment, interactive and cartographic applications are now feasible. Li et al. (2010) suggest a new analysis method which applies Hägerstrand’s Space-Time-Cube (STC; Hägerstrand, 1970) to eye movement data. However, in an interactive three-dimensional STC, identifying and exploring key behaviours can be difficult. In order to ameliorate these difficulties, we propose a variation of the STC method, which uses two-dimensional projections of the STC onto the XT and YT planes. These two-dimensional projections are found to facilitate rapid identification of significant patterns in the data set. A prototype implementing this and other dynamical methods has been developed, and is presented with examples illustrating the benefits of working with two-dimensional projections of the STC.

[Vedettes matières IGN] GéovisualisationRésumé : (Auteur) In different scientific fields, the abbreviation ‘3D’ is used in a multitude of ways. Hence, one might easily lose track of what 3D means in a particular context. 3D is just a generic term which the authors are trying to classify into different groups. An overview of the technical status of 3D technologies serves to explain the importance of the three-dimensionality in cartography. Solid landscape embodiments as well as pseudo-three-dimensional and truly three-dimensional autostereoscopic visualisations on planar displays are treated. Starting with the reasons for the advantages and the necessities for true-3D representations the article deals with the classification and explanation of the different true-3D visualisation techniques so far materialized for geodata, in particular at the Institute for Cartography of the Dresden University of Technology.
