“…A spatial data infrastructure (SDI) is a geographic information web system consisting of a set of resources (catalogues, servers, software, data, applications, and web pages) dedicated to the management of Geographic Information (maps, orthophotos, satellite images, location names, thematic information, among others). Since the appearance of spatial data infrastructure several years ago, there has been a tremendous increase in the spatial data available on the Internet [68].…”

There are several competences and spatial skills to be acquired by the student related to the treatment of geo-information in Science, Technology, Engineering, and Mathematics (STEM) disciplines. Spatial orientation is the spatial skill related to the use of georeferenced information, and geospatial applications (on-line map interfaces) such as the spatial data infrastructure offer a great opportunity for development of this skill. In this report we present several experiments, carried out over five academic years with 559 university students, to improve the spatial orientation skill of the students. Survey learning and wayfinding activities were conducted. First-and second-year university students performed the experiments on a PC and also used digital tablet support. The statistical analysis showed that the students improved their spatial orientation skill with a range from 12.90 (minimum) to 19.21 (maximum) measured with the Perspective Taking Spatial Orientation Test, regardless of the academic year, the hardware (PC or Tablet-PC), or the orientation strategy (survey learning or wayfinding). The second year students improved more than those in their first year. The methodologies employed could be developed by teachers or researchers, and the results presented could be taken as a reference for comparisons in future research in the field of strategy planning with geospatial applications and location-based tools for spatial orientation skill improvement in education.

“…A partir de ces quatre indicateurs tests, nous avons expérimenté la pertinence d'une analyse diachronique du contenu des IDG. Un commentaire plus détaillé de chaque analyse thématique est disponible dans une précédente étude (Noucher et al, 2017). L'objet de la discussion est désormais d'envisager l'originalité mais aussi les atouts et limites de telles analyses au regard des travaux existants et dans la perspective des Geographic Information Observatories présentées en introduction.…”

“…A titre illustratif nous en proposons quatre (tableau 2) qui ont fait l'objet d'une restitution sous la forme de (géo)visualisations pour l'année 2016 (Noucher et al, 2017). Cependant, comme évoqué en introduction, l'un des principaux enjeux des observatoires de l'information géographique est de dépasser la situation à un instant « t » pour suivre le patrimoine de données dans le temps et évaluer son évolution.…”

RESUME. L'extension des usages de l'information géographique génère une profusion de données qui circulent sur de multiples plateformes Web. Accompagner le suivi du contenu de ces plateformes relève aujourd'hui de la gageure tant elles s'apparentent à des boites noires informationnelles et algorithmiques soumises à de fortes dynamiques. Le concept d'observatoire de l'information géographique semble alors approprié pour suivre, analyser et comprendre l'évolution du volume et des flux de données géographiques disponibles et leur utilisation sur une portion de territoire. Néanmoins, sa mise en oeuvre soulève des questions méthodologiques que nous discutons à partir de l'expérimentation d'une observation diachronique du patrimoine de données issues des Infrastructures de Données Géographiques françaises. Nous soulignons en particulier l'importance d'un suivi régulier de ces dispositifs.ABSTRACT. Extensive uses of geographic information generate a data deluge on many Web infrastructures. Monitoring and analyzing the content of these platforms is still a research challenge because these can be considered as very dynamic informational and algorithmic black boxes. The concept of "geographical information observatory" appears as an appropriate mean to monitor, analyze and then provide a better understanding of the evolution of the volume and flows of the spatial data available on a specific web infrastructure. Nevertheless, its implementation raises several methodological questions discussed in this paper, starting from the experimentation of a diachronic data observation of French Spatial Data Infrastructures. Finally, the importance of regular monitoring of these systems is also highlighted.

Qualitative study of the incompatibility of indoor map file formats with location software applications

Indoor maps, and therefore the indoor map data and software that uses them, are used by architects, designers and planners, those in public safety and emergency response, facilities management and even advertising. Presently, the wide range of commonly-used formats for generating indoor maps means that many who would use indoor map applications either must convert indoor map data to another format or re-create the map, which can be time-consuming, costly, and even result in a flawed map. Because the problem is not recognized widely, the benefits that would come from solving it are not widely considered, and so indoor-map related software is not evolving rapidly. This article brings the problem into focus, which should spur enthusiasm to solve it. The article also considers solutions to interoperability problems, and offers what may be the most expedient solution. The solution, in brief, is that automatic conversion between commonplace indoor map file formats may result in data loss, so encouraging software makers to adopt certain formats is more practical than a solution involving file conversions which will be flawed. This paper advocates for a planned solution to indoor map data incompatibility rather than a market-driven solution which might take years longer to effect.
