MotivationMotivation

Accuracy of the communicated information.

Accuracy of the road network: level of generalisation

Accuracy of related areal data: landuse determination

Proposed ApproachProposed Approach

Proposal of a user centred approach for navigation oriented generalization

- The aim of the study is to derive car navigation maps from the base data not only automatically, but also user

centrically.-Perspective representations of most detailed level

of navigation process in terms of content- generalized user centrically

- more accurate presentations

Proposed Approach

Land use determination and network simplification
