[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.

[Termes IGN] visualisation cartographiqueRésumé : (Auteur) Traditionally, research on cartography has primarily been focused on visualisation of outdoor environments. Recently, however, indoor cartography has increasingly attracted attention both from the academic world and from commercial enterprises. Indoor cartography calls for markedly different visualisation strategies. Frameworks for describing map communication and use exist for general maps. But so far, no such framework exists for indoor maps. This article presents and discusses several map types for indoor spaces found in the literature and commercial products. The different characteristics of each one are identified and described. On this basis, a framework for indoor maps is developed and presented. Arbitrary indoor maps can be described by their properties using the framework. This allows indoor maps to be compared and described using a common platform.

[Termes IGN] utilisateurRésumé : (Auteur) Indoor map design is still an uncharted territory. More often than not, existing architectural floor plans are used as visualization means that do not fulfill cartographic requirements. In collaboration between geoinformation science and sociology, we develop and investigate cartographic methods for effective route guidance in indoor environments. The baseline for our evaluation is the annual user studies with up to 1100 participants per year. Since 2009, they were conducted during the “Long Night of Sciences,” a big event where large scientific institutions present themselves to the general public. For the 2011 study, we developed eight maps, which varied in design with respect to two map properties: map perspective and landmark representation. We evaluated the map design features as well as route complexity and sociodemographic characteristics. In order to rate their effect on an user satisfaction as an indicator of navigational success, we carried out a series of analyses of variance. Our results underline the importance of a map design: Map perspective and landmarks alone explain about 30% of the variance in the user satisfaction with maps, which is by far the biggest share in a navigational success.

[Termes IGN] reconstruction d'imageRésumé : (Auteur) Compressive sensing (CS) for urban operations and through-the-wall radar imaging has been shown to be successful in fast data acquisition and moving target localizations. The research in this area thus far has assumed effective removal of wall electromagnetic backscatterings prior to CS application. Wall clutter mitigation can be achieved using full data volume which is, however, in contradiction with the underlying premise of CS. In this paper, we enable joint wall clutter mitigation and CS application using a reduced set of spatial-frequency observations in stepped frequency radar platforms. Specifically, we demonstrate that wall mitigation techniques, such as spatial filtering and subspace projection, can proceed using fewer measurements. We consider both cases of having the same reduced set of frequencies at each of the available antenna locations and also when different frequency measurements are employed at different antenna locations. The latter casts a more challenging problem, as it is not amenable to wall removal using direct implementation of filtering or projection techniques. In this case, we apply CS at each antenna individually to recover the corresponding range profile and estimate the scene response at all frequencies. In applying CS, we use prior knowledge of the wall standoff distance to speed up the convergence of the orthogonal matching pursuit for sparse data reconstruction. Real data are used for validation of the proposed approach.

[Termes IGN] production participativeRésumé : (Auteur) The availability of mobile devices for all has boosted the demand for indoor location-based services such as indoor routing or indoor navigation. Both researchers and companies are trying to adapt well-known outdoor solutions to the requirements of indoor spaces. Crowdsourced geographic information is already a promising new data source for outdoor applications. A logical next step would be to apply this novel paradigm to the indoor world. The authors propose and discuss a new model that extends the scope of Volunteered Geographic Information (VGI) communities - essentially OpenStreetMap - towards indoor spaces. This enables the open collection and usage of indoor information such as emergency navigation in a hotel or personal navigation at the airport. Hence, large-scale availability of indoor VGI would have a positive social impact and add value in many different areas.
