1. A method for display of information for a mobile navigation system comprising:
- selecting characteristics for display according to characteristics of features in a map database, the selecting including;
identifying clusters of maneuvers of a planned route,assigning a score to each cluster of maneuvers based on the characteristics of features present at the locations of the maneuvers,determining a relatively higher scale for times when a cluster having a relatively higher score is to be displayed, and determining a relatively lower scale for times when a cluster having a relatively lower score is to be displayed; and
generating an image for display of a map according to the selected characteristics.

Abstract
A mobile navigation system includes a graphical display for presentation of map information. Map features are selected for presentation on a display. Characteristics for display are also selected. The characteristics for display include a scale for display that varies across the display. An image for display is generated from the selected features according to a selected scale.
