Résumé

Visualization may be a potent looking-glass for peering into both physical and abstract worlds, but our view is always distorted by inaccuracies in measurements, incompleteness of knowledge, and ambiguities in interpretation. To the visualizer, uncertainty is a particular problem. Depiction depends on the placement of marks on paper or screen, and the placement of such a mark can, implicitly, convey confidence that this feature is in this place rather than another, or even that the existence of the feature is accepted and agreed. In this paper, we use the term uncertainty visualization to refer to the problem of acquiring, modelling and representing data while accounting explicitly for the uncertainties that encompass it. We provide an overview of this growing area, and discuss methods of systematically incorporating knowledge of uncertainty in a geovisualization application. We report on ongoing research in a major industrial application to visualize buried assets while reflecting the uncertainty of our knowledge.
