GPS-based navigation devices use large-scale visualizations of the route, where the focus lies on turn instructions. Although efficient on the wayfinding task, this approach does not support survey knowledge acquisition, which is essential for the user to build up a cognitive map and obtain orientation. Another visualization option is the small-scale topographic overview of the route. However, due to the lack of detailed turn information, it is difficult for the user to interpret turn decisions, especially in small display devices. Current route schematization algorithms focus on improving interpretation of turns but ignore context information. Considering this limitation, we propose a schematization method that provides information about turns at decision points and, in the same layout, an overview of the route emphasizing spatial relationshisps with context regional features.
