Abstract :
In the framework of the development of services dedicated to mobile systems, e.g. PDA or PDA-phone plus GPS, we have conducted research that aims at proposing models and architectures for the implementation and deployment of these services.
This research has been conducted in several directions, and the results of this work will be presented in the full paper. First, we have been working on the definition of both a model and architecture for downloading and visualizing multi scale digital maps on mobile systems with a low bandwith connection. Secondly, we have defined a graphical semiology which is adapted to the visualization of digital maps on small size displays. Finally, we have defined a model of intermediation that is based on the use of semi-stuctured data and metadata.
Globally, these research activities aim at proposing services for mobile systems in order to allow access to touristic information depending on the geographic location of the mobile. The results of this research have been implemented in a real environment with digital maps on the city of La Rochelle, France.
