A Conceptual Model For Supporting Multiple Representations And Topology Management

In this paper a joint topology-geometry model is proposed for dealing with multiple representations and topology management to support map generalization. This model offers a solution for efficiently managing both geometry and topology during the map generalization process. Both geometry-oriented generalization techniques and topology-oriented techniques are integrated within this model. Furthermore, by encoding vertical links in this model, the joint topology-geometry model provides support for hierarchical navigation and browsing across the different levels as well as for the proper reconstruction of maps at intermediate levels.
