Özet

This paper proposes a method of implementation of automatic contour line extraction from scanned digital topographic maps. First, color image segmentation is executed to recognize the features on digital topographic maps, second, morphological and filtering 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, matching and reconnecting broken contour lines are proposed.
