[Vedettes matières IGN] GéovisualisationRésumé : (auteur) Geospatial technologies are transforming the practice of the Digital Humanities, and these developments have direct relevance to the practice of scientifically oriented archaeology. The most recent “spatial turn” among digital humanists can be attributed to both the prevalence of tools like ArcGIS that facilitate such investigations as well as an interdisciplinary convergence upon theoretical models that conceive of socially constructed space. This article will briefly review the current state-of-the-art in the field of Spatial History as well as discuss a number of emerging trends such as deep mapping, digital storytelling and data visualization, utilizing examples from a variety of applications. Moreover, archaeologists can benefit from the substantial investments by the academy in the Digital Humanities, particularly in the United States and Canada. In sum, the article proposes that the scope of archaeological applications of geospatial technologies would be productively broadened through an increased engagement with the Digital Humanities.

[Vedettes matières IGN] GéovisualisationRésumé : (auteur) We present a new viewpoint-based approach to improving the exploration effects and efficiency of trajectory datasets. Our approach integrates novel trajectory visualization techniques with algorithms for selecting optimal viewpoints to explore the generated visualization. Both the visualization and the viewpoints will be represented in the form of KML, which can be directly rendered in most of off-the-shelf GIS platforms. By playing the viewpoint sequence and directly utilizing the components of GIS platforms to explore the visualization, the overview status, detailed information, and the time variation characteristics of the trajectories can be quickly captured. A case study and a usability experiment have been conducted on an actual public transportation dataset, justifying the effectiveness of our approach. Comparing with the basic exploration approach without viewpoints, we find our approach increases the speed of information retrieval when analyzing trajectory datasets, and enhances user experiences in 3D trajectory exploration.

[Vedettes matières IGN] GéovisualisationRésumé : (auteur) This paper presents a novel integrated marine visualization framework which focuses on processing, analyzing the multi-dimension spatiotemporal marine data in one workflow. Effective marine data visualization is needed in terms of extracting useful patterns, recognizing changes, and understanding physical processes in oceanography researches. However, the multi-source, multi-format, multi-dimension characteristics of marine data pose a challenge for interactive and feasible (timely) marine data analysis and visualization in one workflow. And, global multi-resolution virtual terrain environment is also needed to give oceanographers and the public a real geographic background reference and to help them to identify the geographical variation of ocean phenomena. This paper introduces a data integration and processing method to efficiently visualize and analyze the heterogeneous marine data. Based on the data we processed, several GPU-based visualization methods are explored to interactively demonstrate marine data. GPU-tessellated global terrain rendering using ETOPO1 data is realized and the video memory usage is controlled to ensure high efficiency. A modified ray-casting algorithm for the uneven multi-section Argo volume data is also presented and the transfer function is designed to analyze the 3D structure of ocean phenomena. Based on the framework we designed, an integrated visualization system is realized. The effectiveness and efficiency of the framework is demonstrated. This system is expected to make a significant contribution to the demonstration and understanding of marine physical process in a virtual global environment.

[Vedettes matières IGN] GéovisualisationRésumé : (auteur) The main purpose of this paper is to develop a new method for visualizing knowledge production which is attentive to the multiple elements embedded in research processes. In particular, we seek to problematise the representation of scholarship indicators by depicting theoretical contributions and field sites along a spectrum, rather than as discrete points, recursively and relationally constituted. The primary aim of our visualisations is to capture text and context, and codified and tacit knowledge. First, we offer a conventional representation of the location of selected dominant critical theories in Geography, arguing that current methods reinforce ‘lopsided’ geographies of knowledge production. Normative practices of data visualisation and representation captured in our two examples privilege certain elements centred on authorship and tend to silence the contexts informing research. Second, we borrow the term and method of chromatography, a tool used in the natural sciences but here conceived in its more literal sense of ‘writing the separations’. Our ‘chromatographical’ representations attempt to unbundle components currently absorbed by formal indicators of knowledge production. Such counter mappings attempt to convey the relational aspect of research between countries imbricated in the propagation of exemplary critical geographic theories. We conclude with a discussion of the implications that the disaggregation of value has for scholars and their research.

[Vedettes matières IGN] GéovisualisationRésumé : (auteur) We investigate task performance and reading characteristics for scatterplots (Cartesian coordinates) and parallel coordinates. In a controlled eye-tracking study, we asked 24 participants to assess the relative distance of points in multidimensional space, depending on the diagram type (parallel coordinates or a horizontal collection of scatterplots), the number of data dimensions (2, 4, 6, or 8), and the relative distance between points (15%, 20%, or 25%). For a given reference point and two target points, we instructed participants to choose the target point that was closer to the reference point in multidimensional space. We present a visual scanning model that describes different strategies to solve this retrieval task for both diagram types, and propose corresponding hypotheses that we test using task completion time, accuracy, and gaze positions as dependent variables. Our results show that scatterplots outperform parallel coordinates significantly in 2 dimensions, however, the task was solved more quickly and more accurately with parallel coordinates in 8 dimensions. The eye-tracking data further shows significant differences between Cartesian and parallel coordinates, as well as between different numbers of dimensions. For parallel coordinates, there is a clear trend toward shorter fixations and longer saccades with increasing number of dimensions. Using an area-of-interest (AOI) based approach, we identify different reading strategies for each diagram type: For parallel coordinates, the participants’ gaze frequently jumped back and forth between pairs of axes, while axes were rarely focused on when viewing Cartesian coordinates. We further found that participants’ attention is biased: toward the center of the whole plotfor parallel coordinates and skewed to the center/left side for Cartesian coordinates. We anticipate that these results may support the design of more effective visualizations for multidimensional data.
