[Termes IGN] visualisation cartographiqueRésumé : (Auteur) The increasing prevalence of user-generated, or volunteered, geographic information is changing established practices of spatial data production and use in ways that were largely unanticipated in nature or in scope. This paper investigates one dimension of VGI use that has received relatively little attention to date, namely the influence of different cartographic visualisation methods on citizens' ability to explore and understand VGI. Following a brief review of key challenges related to VGI use, the paper describes a web-based software prototype that was designed to allow users to compare several simple geovisualisation and data filtering techniques for VGI exploration. Next, attention is directed to a specific study context where citizens used the software tool to explore a rich data set of locally-produced VGI related to community assets. The paper concludes with a discussion of the results from this experiment.

[Termes IGN] vue 3DRésumé : (Auteur) In this paper we introduce analytical three-dimensional (3D) views as a means for effective and comprehensible information delivery, using virtual globes and the third dimension as an additional information carrier. Four case studies are presented, in which information extraction results from very high spatial resolution (VHSR) satellite images were conditioned and aggregated or disaggregated to regular spatial units. The case studies were embedded in the context of: (1) urban life quality assessment (Salzburg/Austria); (2) post-disaster assessment (Harare/Zimbabwe); (3) emergency response (Lukole/Tanzania); and (4) contingency planning (faked crisis scenario/Germany). The results are made available in different virtual globe environments, using the implemented contextual data (such as satellite imagery, aerial photographs, and auxiliary geodata) as valuable additional context information. Both day-to-day users and high-level decision makers are addressees of this tailored information product. The degree of abstraction required for understanding a complex analytical content is balanced with the ease and appeal by which the context is conveyed.
