Navigation was one of the first applications in the context of
location-based services. Today, there is a wealth of navigation
systems available, especially for cars, and the rise of mobile
communication will enable more sophisticated systems which can even
take the current traffic situation into account. Small and more
powerful devices for mobile communication like modern mobile phones
and personal digital assistants (PDAs) will further extend the usage
of navigation applications beyond the scope of car navigation.
It is one of our goals to provide a value-added service to NEXUS
applications to support them in navigational tasks. To realize such
a service, we need to store topological information in the Augmented
World Schema (AWS). The navigation service will use this information
as a basis for the navigation process. Therefore, the Standard Class
Schema of the AWS is enriched by several navigational objects and
also by various mobile object types. To reduce the modeling effort,
we want to be able to integrate existing topological information,
e.g., GDF and ATKIS data, into our model, and therefore we need a
mapping from these data formats to our topological description in
the Augmented World Schema. Furthermore, we are aiming at combining
navigation approaches for outdoor and indoor areas as well as for
different types of locomotion (intermodal navigation). In order to
optimize navigation procedures we further intend to develop
techniques allowing for hier-archical algorithms that can be run on
different levels of details of the underlying data.
