| Abstract: | Firstly the paper discusses the route planning algorithm of wide region scope.Then,a multi-level road network data model is established,which suits for the algorithm of multi-scale route planning,and an effective method of establishing multi-scale road network database and multi-scale road network topology is put forward,a route planning algorithm is put forward,which suits for embedded GIS based on multi-level road network data model. |
