Effective Route Maps
Route maps, which depict a path from one location to another, are one of the most common forms of graphic communication. Although creating a route map may seem to be a straightforward task, the underlying design of most route maps is quite complex. (M. Agrawala, C. Stolte)
Maneesh Agrawala and Chris Stolte from Stanford University present in their paper a set of cartographic generalization techniques specifically designed to improve the usability of route maps. Feedback from over 2200 users indicates that almost all believe LineDrive maps are preferable to using standard computer-generated route maps alone.
