Automated model generalization of schematic network maps based on dynamic segmentation

Lines do not represent the routes completely and effectiveness based on arc-node model. In this paper, a new model generalization of schematic network maps based on dynamic segment is proposed. Routes are constructed according to the road segment attribute similarity and geometry continuous. Based on route networks, a new method comprising shapes simplification and displacement is proposed to schematize road network quickly. A case study for schematic map was carried out and analyzed. Initial experimental studies show that this approach is more effective in evidence on making features maximum clearly on screen.
