In this paper, we introduce an information model for describing this content. The model covers the physical environment faced by a person moving on foot. We have used the Unified Modeling Language class diagrams to formalize the information model on a conceptual level. The features are divided into two abstract top-level classes: one allowing pedestrian access and the other hindering it. A consistent and comprehensive pedestrian network is at the core of the model. The model also covers other geographical information to increase accessibility. The aim of the created information model is to help data providers to collect and store appropriate data using the appropriate methods.

[Termes IGN] piétonRésumé : (Auteur) As populations age, more and more people have some kind of restrictions on their mobility. In order to increase the potential of mobility-impaired persons to move around and navigate independently, information on the accessibility of the environment should be supported by map services and delivered together with spatial information to their devices for personal navigation. Spatial databases for pedestrian route planning should contain more detailed information on accessibility, such as pavement surfaces, slopes, and stairs. This study examines a wide range of examples of map services in Finland in terms of the extent to which they support accessibility. The authors then provide and discuss a proposal for the information content of a geospatial database to fulfil the requirements of users with impairments. With guidelines for data content, data classification, and functionality, map information can be developed so that it is also more useful for special user groups and makes the environment more accessible for everyone.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) Whilst technology may fundamentally change how we handle spatial information, the underly-ing principles of effective visualisation and cartographic design remain the same. Generalisation is but one essential piece of the jigsaw, integrated among a set of techniques and technologies that extend from capture and storage through to visualisation and interaction. There are many chal-lenging issues in generalisation research: from modelling the complex decision making processes inherent in the art and science of cartography, through to interaction models that support easy interaction and exploration of geographic phenomenon across a continuum of scales. Moderately high levels of automation are now achievable but there remains an exciting set of research challenges - challenges that are evolving in response to the disruptive nature of IT. In this chapter, we present a set of challenges as a pointer to a research agenda that includes among other things, generalisation of global datasets, better evaluation methodologies, and better integration of reasoning about space in order to support autonomous solutions in map generalisation. The importance of all research connected with generalisation is built around the concept that scale is intrinsic to ideas of geographic meaning and is therefore critical to geographical problem solving.

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) The increased use of the Web and the Mobile Internet as a platform for geospatial applications necessitates development of improved interoperability between. Computing systems and underscores the need to apply standardized network technologies in processes dealing with spatial data. The generalization approach applicable in network-based spatial data services may be based on different technologies, compared with traditional cartographic generalization. Here, the use of Extensible Markup Language (XML) techniques in data transformations, with special emphasis on cartographic generalization, is presented. The research presented in the paper is focused on the Extensible Style-sheet Language Transformation (XSLT) process as a means to generalize XML-encoded spatial data in real time. The prototype system for real-time generalization developed at the Finnish Geodetic Institute (FGI) applies Geography Markup Language (GML) as spatial data encoding and Scalable Vector Graphics (SVG) images for map visualization. The data-access interface conforms with the Open GIS Consortium's (OGC) Web Feature Service specification. The implemented generalization operators include selection, building simplification and aggregation, and were processed during the request response dialogue in the network. The generalization process was tested on topographic datasets and results visualized on the Web and Personal Digital Assistants (PDAs). Although XML-based computing processes are generally understood to yield poor performance ratings, the work shows that intelligent XSLT generalization processes can be introduced without degrading the performance of a mobile map service.

[Vedettes matières IGN] CartologieRésumé : (Auteur) Cartographers' main objective in map design is to create in the mind of a map reader (i.e. user) an abstraction of the real world appropriate to the map's purpose. The final result depends, not only on the cartographers', but also users' skills and ways to perceive, as well as on the map usage situation. Interruptions during map reading process of mobile maps occur, when the conceptual models of the cartographer and the user do not match, e.g. if the user does not understand the symbols, or the overall layout of the mobile map. This can be frustrating from the users' point of view. It is thought here, that by bringing context awareness into the maps on mobile devices, interruptions in map reading process could be decreased, by providing each user with symbols that are adapted to the usage situation and user preferences in real-time. In this paper some ideas, of how to implement context awareness into mobile maps by personalisation, are presented.
