Abstract

Abstract: In order to evaluate the quality of the road in navigation electronic map,a method of automatic comparison and analysis of road in multi-source navigation electronic map is proposed.Road networks are automatically extracted firstly,and difference between the road networks in multi-source navigation electronic map is detected using algorithms based on buffer analysis.Intersections of road are detected afterwards using Shi-Tomasi operator and the number of road is count,which realizes quantitative comparison and analysis of multi-source navigation electronic map.Experiments have proved the effectiveness of this method.

Key words: navigation electronic map, road, buffer analysis, difference detection, road intersection
