[Vedettes matières IGN] GéovisualisationRésumé : (Auteur) This article seeks to address the gap between the quantitative, summative data that are typically engaged in geovisual analytics and the more personal, experiential ways of knowledge construction accentuated by qualitative GIS. By incorporating diverse forms of data within a high-dimensional conceptual framework, we set out a type of qualitative geovisual analytics. This approach is attentive to the epistemological limitations of singular data sources and highlights the multiple ways of exploring neighbourhoods. The article reports on a project that used an online survey, including collection of personal impressions of San Diego neighbourhoods based on street-level video. Three attribute spaces are conceptualized: survey respondents' characteristics, attributes of San Diego neighbourhoods, and characteristics of the words used to describe these neighbourhoods. The self-organizing map (SOM) technique was used to reduce the dimensionality of these attribute spaces for visual exploration. This approach makes several important contributions, including a demonstration of “scaling up” the work that has been done in qualitative GIS. It productively integrates experiential data with a geovisual analytics approach and reaffirms the multiple meanings of visualization.

[Termes IGN] représentation cartographiqueRésumé : (Auteur) Local regression methods can provide specific information about individual observations (places) in spatial analysis that is often useful in understanding non-stationary covariate relationships. Geographically weighted regression (GWR) is one widely used local regression model whose parameter estimates are mapped as continuous or discrete surfaces. A less frequently used local regression method used in spatial analysis is quantile regression (QR). One drawback to the use of QR is its restricted visualization possibilities; currently, regression parameter summaries for QR are visualized only as line graphs that plot parameter estimates against quantile levels. This article presents a method that also permits the spatial display of these values in a choropleth map so that QR can be added to the cartographic repertoire of exploratory data models.

[Termes IGN] système de gestion de connaissancesRésumé : (Auteur) Digital cartography offers exciting opportunities for recording indigenous knowledge, particularly in contexts where a people's relationship to the land has high cultural significance. Canada's north offers a useful case study of both the opportunities and challenges of such projects. Through the Geomatics and Cartographic Research Centre (GCRC), Inuit peoples have been invited to become partners in innovative digital mapping projects, including creating atlases of traditional place names, recording the patterns and movement of sea ice, and recording previously uncharted and often shifting traditional routes over ice and tundra. Such projects have generated interest in local communities because of their potential to record and preserve traditional knowledge and because they offer an attractive visual and multimedia interface that can address linguistic and cultural concerns. But given corporations' growing interest in the natural resources of the Arctic and the concomitant rise in government concern about claims to Arctic sovereignty, such maps may also be of interest to a broad range of actors and for a variety of purposes. Because these projects rely heavily upon, and record, oral knowledge, and because they convert such knowledge into highly malleable and easily disseminated digital content, they raise challenging issues around informed consent, intellectual and cultural property, and privacy. This article identifies and examines these issues and describes the collaborative and interdisciplinary research established to identify and address the use of traditional knowledge in digital cartography.

[Termes IGN] visualisation cartographiqueRésumé : (Auteur) Increased attention to global climate change in recent years has resulted in a wide array of maps and geovisualizations that forecast various scenarios. Since many consequences of climate change are inherently geographic in nature, effective cartographic representations that depict these risks are valuable for planning and mitigation purposes. In particular, sea-level rise resulting from climate change calls attention to the numerous representation issues that warrant consideration for hazard and risk mapping in general, including categorizing and representing risk, selecting an appropriate level of realism, and displaying potential impacts of a hazard on human populations as well as on the natural and built environments. Using examples of potential inundation from sea-level rise at global, regional, and local scales, the authors propose a conceptual framework of key cartographic considerations for maps, Web-based mashups, and geovisualizations that depict risk. The cartographic framework presented here may be extended to other risks of an ambiguous or fuzzy nature and may be used to organize key future research areas for hazard or risk mapping in general.

[Termes IGN] visualisation cartographiqueRésumé : (Auteur) Location sharing in indoor environments is limited by the sparse availability of indoor positioning and lack of geographical building data. Recently, several solutions have begun to implement digital maps for use in indoor space. The map design is often a variant of floor-plan maps. Whereas massive databases and GIS exist for outdoor use, the majority of indoor environments are not yet available in a consistent digital format. This dearth of indoor maps is problematic, as navigating multistorey buildings is known to create greater difficulty in maintaining spatial orientation and developing accurate cognitive maps. The development of standardized, more intuitive indoor maps can address this vexing problem. The authors therefore present an alternative solution to current indoor map design that explores the possibility of using colour to represent the vertical dimension on the map. Importantly, this solution is independent of existing geographical building data. The new design is hypothesized to do a better job than existing solutions of facilitating the integration of indoor spaces. Findings from a human experiment with 251 participants demonstrate that the vertical colour map is a valid alternative to the regular floor-plan map.
