Abstract :
This paper proposes a method of implementation of automatic contour line extraction from scanned digital to pographic maps. First, color image segmentation is executed to recognize the features on digital topographic maps, second, morphological and filltering operations are presented to eliminate all unwanted information from digital topographic map except from contour lines. Then, resolving the terminal and crossed points is processed, finally, match-ing and reconnecting broken contour lines are proposed.
