The vast majority of the information content of the internet is in
relation to some physical location. In order to support the
development of applications, which exploit this fact, it makes sense
to offer a platform that provides fundamental spatial services. The
aim of the Nexus-project, which embeds this thesis, is to develop
such a platform.
It requires a model of the physical space to be able to make spatial
services available. The server-component, which is to be developed
as a part of this thesis, manages spatial models that are enriched
by so-called virtual objects. Virtual objects can only be perceived
via the platform. At augmented locations they provide information.
Among others, the server- component offers spatial analyses and
navigation support. Also, the real world can be manipulated by the
platform.
This thesis encompasses the development of a prototypical
server-component that is based on a geographical information system.
Moreover, it defines the spatial services of the server-component.
Finally, it examines the architecture of a federated system of
multiple server-components from a conceptual point of view
