First Claim
1. A display system for displaying a net of distinct and interconnected geographical paths having various path orientations and comprising:
- (a) storage means for storing said net as an arrangement of vectors each associated with one of said paths, said vectors including a geographical name comprised of characters for its associated path,(b) select means for signalling an intended selection from said net,(c) reading and routing means controlled by said select means for reading said storage means and outputting said selection,(d) display means for displaying said selection including at least one of said paths in its actual orientation, said display means comprising font means for generating a character font for the characters of a name to be displayed adjacent the displayed geographical path of the selection,(e) each said character being displayable in one of a plurality of different character orientations,(f) means for determining the path orientation of each segment of the displayed path where a particular character of its associated name is to be displayed,(g) means for displaying the particular character with one of its character orientations that substantially follows the determined path orientation of the adjacent path segment.

Abstract
Display system for displaying a net of interconnected geographical paths provided with associated geographical names and road vehicle with on-board road-based navigation system having such display system The display system allows to display a steady net of distinct and interconnected geographical paths and stores the net as an arrangement of vectors each associated to a particular path. First, an intended selection is read from the net for displaying. The storage contains the vectors often provided with an associated geographical name. For easy and clear display, the system has a font generator for the path name for when ready for display, displaying the name as a row of characters alongside its associated displayed path while featuring a multi-valued and finite orientation repertoire for the characters.
