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.
