Public [article]  inCartography and Geographic Information Science > vol 34 n° 4 (October 2007) . - pp 247 - 257 Titre : Towards ubiquitous cartography Type de document : Article/Communication Auteurs : Georg Gartner, Auteur Année de publication : 2007 Article en page(s) : pp 247 - 257 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie numérique [Termes IGN] cartographie dynamique [Termes IGN] cartographie par internet [Termes IGN] navigation terrestre [Termes IGN] point de repère [Termes IGN] positionnement cinématique en temps réel [Termes IGN] service fondé sur la position [Termes IGN] visualisation cartographique Résumé : (Auteur) Computer-generated maps have become commonplace over the past decade. Most internet search engines, for example, have the ability to generate maps in response to spatial queries and routes between specified origins and destinations. Advances in mobile computing technologies provide access to these mapping capabilities from virtually any location on the Earth's surface. Maps and map-making have become ubiquitous, and this phenomenon requires cartographers to rethink basic concepts about map design and map use. In this special issue, we present five research projects that are focused on the emerging field of ubiquitous cartography. These projects were selected, in part, because they are representative of key research challenges that face the cartographic research community. In this introductory paper, key terms are defined and research challenges outlined. By way of this collected set of papers, ubiquitous cartography is presented as a new and important arena for cartographic research.

User aspects of adaptative visualization for mobile maps / Annu-Maaria Nivala in Cartography and Geographic Information Science, vol 34 n° 4 (October 2007)  

Public [article]  inCartography and Geographic Information Science > vol 34 n° 4 (October 2007) . - pp 275 - 284 Titre : User aspects of adaptative visualization for mobile maps Type de document : Article/Communication Auteurs : Annu-Maaria Nivala, Auteur Année de publication : 2007 Article en page(s) : pp 275 - 284 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie numérique [Termes IGN] appareil portable [Termes IGN] conception cartographique [Termes IGN] lecture de carte [Termes IGN] petit écran [Termes IGN] positionnement cinématique en temps réel [Termes IGN] sémiologie graphique [Termes IGN] symbole graphique [Termes IGN] visualisation cartographique Résumé : (Auteur) The objective of map design is to create, in the mind of map users, an abstraction of the real world appropriate to the map's purpose. The success of the design depends not only on the cartographer's skill but also on the user's ability to read the map and on the particular circumstances of its use. If the user does not understand the meaning of the map symbols, this may lead to frustration or misinterpretations. If, in a mobile map context, users can be provided, in real-time, with map symbols adapted to particular use situations and user preferences, more effective map reading could result. This paper studies those user aspects where map symbols and other visualization are adapted for mobile users' specific needs. A discussion on the importance of understanding cartographic principles in mobile map design is followed by the description of an adaptive mobile map service implemented within an EU project called "GiMoDig." This service delivers maps with different point of interest (PoI) symbols and different map designs for varying user groups in different use situations. The paper describes how the cartographic design was evaluated and how the intuitivity of the map symbols was tested. Finally, conclusions and recommendations for future research topics are discussed.

Wireless campus LBS: a test bed for WiFi positioning and location based services / B. Kobben in Cartography and Geographic Information Science, vol 34 n° 4 (October 2007)  

Public [article]  inCartography and Geographic Information Science > vol 34 n° 4 (October 2007) . - pp 285 - 292 Titre : Wireless campus LBS: a test bed for WiFi positioning and location based services Type de document : Article/Communication Auteurs : B.

Initiated in early 2005, the project's research team is comprised of members from the University of Twente Computer Architecture Design and Test for Embedded Systems group, the UT department of Information Technology, Library and Education, and the International Institute for Geo-Information Science and Earth Observation. The research has focused on Wireless LAN positioning techniques and contextually aware data management systems for ubiquitous computing. The system delivers mapping information for LBS and mobile applications through the use of adaptive, cartography-aware database objects. In this paper, we describe the theoretical background of LBS and positioning services in location-aware GIS and database technology, the University of Twente Wireless Campus, and the prototype we developed for providing positioning and location-based services using that Wireless Campus environment.

Place-tagged podcasts with synchronized maps on mobile media players / M. Arikawa in Cartography and Geographic Information Science, vol 34 n° 4 (October 2007)  

Public [article]  inCartography and Geographic Information Science > vol 34 n° 4 (October 2007) . - pp 293 - 303 Titre : Place-tagged podcasts with synchronized maps on mobile media players Type de document : Article/Communication Auteurs : M. Arikawa, Auteur ; K. Tsuruoka, Auteur ; M. Fujita, Auteur ; A. Ome, Auteur Année de publication : 2007 Article en page(s) : pp 293 - 303 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie numérique [Termes IGN] géonavigateur [Termes IGN] positionnement cinématique en temps réel [Termes IGN] représentation mentale spatiale Résumé : (Auteur) PodWalks are a new kind of Podcasts where virtual narrators guide users through real-world spaces. PodWalks can increase a user's appreciation of real spaces by connecting them to audio tours stored on portable media players that can be listened to any time and anywhere without using mobile telecommunication services. One disadvantage of PodWalks is that it can be difficult for listeners to synchronize their locations with the location that the narrator is describing and, as a result, listeners become disoriented. To solve this problem we propose a new framework—maPodWalks—as an extension to PodWalks which provides maps that are synchronized to the narrations on mobile media players. By forming linkages between virtual and real-world experiences, maPodWalks help users develop mental maps of places of interest. In this paper, we discuss the characteristics of maPodWalks and present a prototype maPodWalk Maker that allows users to easily create geocoded audio tours. The results of system tests comparing the performance of PodWalks and maPodWalks are reported as well.

Augmentation of indoor positioning systems with a barometric pressure sensor for direct altitude determination in a multi-storey building / Guenther Retscher in Cartography and Geographic Information Science, vol 34 n° 4 (October 2007)  

Public [article]  inCartography and Geographic Information Science > vol 34 n° 4 (October 2007) . - pp 305 - 310 Titre : Augmentation of indoor positioning systems with a barometric pressure sensor for direct altitude determination in a multi-storey building Type de document : Article/Communication Auteurs : Guenther Retscher, Auteur Année de publication : 2007 Article en page(s) : pp 305 - 310 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Navigation et positionnement [Termes IGN] altitude [Termes IGN] données localisées 3D [Termes IGN] GPS assisté pour la navigation (technologies) [Termes IGN] navigation pédestre [Termes IGN] positionnement en intérieur [Termes IGN] pression atmosphérique Résumé : (Auteur) To determine the correct floor of a user in a multi-storey building using pedestrian navigation and guidance services is a challenging task, as most common indoor location techniques provide only 2D position determination. Consequently, it is recommended to augment the position determination system with a barometric pressure sensor for direct observation of height differences. In the research project NAVIO (Pedestrian Navigation Systems in Combined Indoor/Outdoor Environments), tests with a barometric pressure sensor have been performed and their results are presented in this paper. The tests show that using a barometric pressure sensor, the building floor at which a person is located can be determined with the standard deviation of better than 1 0.5 m.
