| Abstract: |
Location-aware systems provide customised services or applications
according to users’ locations. While much research has been carried
out in developing models to represent location information and spatial
relationships, it is usually limited to modelling simple environments
(cf. [13,19,3]). This paper proposes a unified space model for more
complex environments (e.g., city plan or forest). This space model
provides a flexible, expressive, and powerful spatial representation.
It also proposes a new data structure – an integrated lattice and
graph model – to express comprehensive spatial relationships. This
structure not only provides multiple graphs at different abstraction
levels, but it also collapses the whole map into smaller local graphs.
This mechanism is beneficial in reducing the complexity of creating
and maintaining a map and improving the efficiency of path finding
algorithms. |
