| Abstract: | Road extraction from topographic map and road network generation are the key techniques in electronic navigation,city planning,electric power and transportation systems,etc.Based on the elements extraction algorithm of mathematical morphology and nodal analysis,by topographic map preprocessing and road node judgment,the road extraction from binary topographic map is implemented.By analyzing the road information requirements in shortest path analysis system,the road network topological structure can be generated.Experiments on prototype system show that the algorithm presented in this paper is reasonable and feasible. |
