Abstract

Schematic maps are effective tools for representing information about the physical environment and make user easy navigate for wayfinding. Evidence have shown that identifying how many categories of directions in urban street network environments, building taxonomy of branching points, and establishing a hierarchy of connecting roads will help produce effective schematic maps to ease wayfinding. Taking road semantic information and user demands into account, we first build the vector data model of hierarchy of connecting roads. Then we propose the four generalization algorithm and show the framework of how to generate schematic maps. Finally, schematic map on demand is designed in a concrete experiment, while keeping the topological consistency of the road network between original and schematic map.
