An automatic recognition method to extract individual map components from large-scale maps in a digital format is proposed. This method recognizes the components on the basis of their geometric features and of drawing regulations of national large-scale maps of Japan. The geometric features are obtained by binary image processing techniques such as labeling, border tracing, line tracking, and thinning. At present, the method is capable of extracting buildings, railways, and contour lines. Experimental results have shown high extraction rates for the method.
