[Termes IGN] qualité des donnéesRésumé : (Auteur) OpenStreetMap (OSM) is one of the most popular examples of a Volunteered Geographic Information (VGI) project. In the past years it has become a serious alternative source for geodata. Since the quality of OSM data can vary strongly, different aspects have been investigated in several scientific studies. In most cases the data is compared with commercial or administrative datasets which, however, are not always accessible due to the lack of availability, contradictory licensing restrictions or high procurement costs. In this investigation a framework containing more than 25 methods and indicators is presented, allowing OSM quality assessments based solely on the data's history. Without the usage of a reference data set, approximate statements on OSM data quality are possible. For this purpose existing methods are taken up, developed further, and integrated into an extensible open source framework. This enables arbitrarily repeatable intrinsic OSM quality analyses for any part of the world.

[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.

[Termes IGN] Web View ServiceRésumé : (Editeur) [introduction] The Open Geospatial Consortium (OGC) has published three new candidate standards which are related to the 3D GeoWeb as public discussion papers (DP) on its website. These are: a revised version of the Web 3D Service (W3DS), the Web View Service (WVS), an extension profile of the Symbology Encoding Specification for 3D (SE 3D) has been added that can be used with the both services. These establish a new family of 3D portrayal services focusing on virtual 3D maps, interactive virtual environments, and 3D cartographic visualization.

[Termes IGN] service fondé sur la positionRésumé : (Editeur) The book is divided into three parts: theory, method and implementation. Starting with a summary of the state-of-the-art in mobile technologies, the first part analyses their impacts on cartography and pinpoints the missing theories concerned with the development of map-based mobile services. A conceptual framework of mobile cartography is then introduced with the emphasis on mobile usage context. The second part is devoted to the design methodology under the constraints defined in the theoretical framework. A core issue deals with personalised mobile map services. The final part demonstrates the feasibility of the methods by using application scenarios. The accompanying CD-ROM contains the PDF-Files in colour. Note de contenu : 1. Map-based mobile services
