An experiment was conducted where participants were given the task to decide building locations, taking into account homeowners’ preferences as well as dilemmas imposed by flood risks at the site. Two general types of visualisations for presenting uncertainties from ensemble modelling were evaluated: (1) uncertainty maps, which used aggregated ensemble results; and (2) performance bars showing all individual simulation outputs from the ensemble. Both were supplemented with either two-dimensional (2D) or three-dimensional (3D) contextual information, to give an overview of the area.
The results showed that the type of uncertainty visualisation was highly influential on users’ decisions, whereas the representation of the contextual information (2D or 3D) was not. Visualisation with performance bars was more intuitive and effective for the task performed than the uncertainty map. It clearly affected users’ decisions in avoiding certain-to-be-flooded areas. Patterns to which the distances were decided from the homeowners’ preferred positions and the uncertainties were similar, when the 2D and 3D map models were used side by side with the uncertainty map. On the other hand, contextual information affected the time to solve the task. With the 3D map, it took the participants longer time to decide the locations, compared with the other combinations using the 2D model.
Designing the visualisation so as to provide more detailed information made respondents avoid dangerous decisions. This has also led to less variation in their overall responses.Numéro de notice : A2016-087 Affiliation des auteurs : non IGN Thématique : GEOMATIQUE Nature : Article nature-HAL : ArtAvecCL-RevueIntern DOI : 10.1080/13658816.2015.1085539 En ligne : https://doi.org/10.1080/13658816.2015.1085539 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=79872

It commenced in 1992 in Buffalo, and has been held every year since. Meetings have been held in North America and Asia in Beijing (1993), Calgary (1994), Hong Kong (1995), West Palm Beach (1996), Taipei (1997), Beijing (1998), Ann Arbor (1999), Monterey (2000), Bangkok (2001), Nanjing (2002), and Toronto (2003, cancelled due to the outbreak of SARS). This is the premier event organized by the University of Gävle, together with the Association of Chinese Professionals in Geographic Information Science (CPGIS-abroad. This conference is the first of the series that takes place in Europe, hence the subtitle of the conference - bridging the Pacific and Atlantic. I believe it offers an opportunity for all professionals involved in research and development of geographic information systems, global position systems and remote sensing to discuss new theories and technologies around geoinformatics research. Based on the extended abstracts and following advice from the program committee, the organizing committee selected 108 papers (involving 264 authors from 29 different countries) around 10 different themes included in the proceedings. The conference themes include some emerging research issues such as location-based services and geovisualization as well as long studied conventional issues. As a post-conference publication effort, some selected papers around special themes will go another round of review process to be published in special issues with some scientific journals. The organization of the event is rather team-oriented work. On behalf of the organizing committee, I would like to thank CPGIS, the University of Gävle, our sponsors and all those individuals involved in making it a successful event, in particular, Kickan Fahlstedt, the conference secretary who took most administrative and organizational matters into her hands; Anders Brandt who read the papers and provided useful comments to the authors; Bengt Eriksson, Stig-Göran Mårtensson, and Bengt Rystedt who are always very supportive for the event; Peter Fisher and David Maguire who share their vision on current geoinformatics research; and all the authors who contribute with their papers of high quality. Last but not least, the following colleagues or students deserve special thanks for their contributions to the organization of the conference: Gunter Göckelmann, Pia Ollert- Hallqvist, Anna Hansson, Neta Hedberg, Elisabeth Hugg, Mikael Johansson, Rebecca Jonsson, Hendrik Loch, Bengt-Olof Lundinger, Staffan Nygren, Kaj Wejander, and Wenjun Xie.
