[Vedettes matières IGN] GéovisualisationRésumé : (auteur) In this study, we propose an interactive information system for wind turbine siting, considering its visual and sound externalities. This system is an integration of game engine, GIS and analytical sound propagation model in a unified 3D web environment. The game engine–GIS integration provides a 3D virtual environment where users can navigate through the existing geospatial data of the whole country and place different wind turbine types to explore their visual impact on the landscape. The integration of a sound propagation model in the game engine–GIS supports the real-time calculation and feedback regarding wind turbine sound at the surrounding buildings. The platform's GIS component enables massive (on-the-fly) georeferenced data utilization through tiling techniques as well as data accessibility and interoperability via cloud-based architecture and open geospatial standard protocols. The game engine, on the other hand, supports performance optimization for both data display and sound model calculations.

[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.

[Termes IGN] vingtième siècleRésumé : (Auteur) The video game industry revolutionized the game market from the 1970s onwards. Stationary video game machines, such as “coin-ops” and, later, consoles for home entertainment made it possible to experience and interact with new virtual environments. Based on technical innovations, early video games already included different graphic and auditory effects that were used to present and emphasize the spatial dimension of game stories. One of the most famous and successful video game series that “told” spatial stories and included many visualizations of virtual topographies was Nintendo's Super Mario series. Nintendo developed diverse video game topographies including different interactive and animated cartographic media throughout the Super Mario series. These maps were early and fundamental examples that were user-friendly and suitable for children. Moreover, they established a basis for future video game spaces, and the techniques used to create, animate, and visualize these maps have also found their ways into other applications of cartography and geomatics. It seems that the early worlds of Super Mario animated cartographers to animate cartographic visualizations. This article presents the characteristic spatial structures and cartographic techniques found in early Super Mario games, from the arcade classic Donkey Kong (1981) to the Super Nintendo classic Super Mario Kart (1992). The meaning of these structures and techniques for other cartographic applications is discussed.

[Termes IGN] télémétrie laser terrestreRésumé : (auteur) The authors have developed a novel system framework for a historic preservation system utilising open standards and open source tools. The framework enables the integration of open standard 3D models and GIS in a virtual environment (VE). It also allows the storage and harvesting of data via an open source web-based central repository. The framework is designed for bi-directional interoperability when utilised for monument tracking, preservation, conservation, re-excavation, etc. To date, no such system framework exists for the development and management of historic monuments using open standards e57 for terrestrial laser scanning (TLS) data, the industry foundation classes (IFC) for 3D semantic rich models, and CityGML for integrating IFC and GIS in a VE. The web-based VE is accessed from the BimServer and envisaged for monitoring monument erosion, movement, and damage to monuments by human activity or nature, collaboration between different industry actors to share knowledge, experience, and expertise globally, etc. Numéro de notice : A2016--162 Affiliation des auteurs : non IGN Thématique : GEOMATIQUE/IMAGERIE Nature : Article DOI : 10.4018/IJ3DIM.2016100101 En ligne : https://doi.org/10.4018/IJ3DIM.2016100101 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=85915

[Termes IGN] prise en compte du contexteRésumé : (auteur) Navigation is a task performed in both large and small scale environments. Landmarks within an environment are of great benefit to these navigational tasks, but in large rural environments such landmarks may be sparse. It has been shown that landmarks need not be purely visual and that a change in context for a feature can make it become a landmark against its surroundings (such as being provided with significant meaning). Such meaning could be added through personal experience or by informing the observer via some form of communication. To investigate the effects of providing such contextual information on navigational performance, experiments were conducted in a large rural virtual environment where the delivery method of the information was varied between onscreen and PDA display. Users were instructed to perform a route tracing navigation task. In some instances users were presented with textual information about specific locations within the environment which appeared when they were in the vicinity of the location. Both quantitative and qualitative data were collected and analyzed, with results indicating that although the actual performance in the task was not significantly improved, users felt that their performance was better and the task easier when they were presented with the contextual information.
