<p>For making digital maps by using the raster-vector conversion of printed binary topographic maps, one of the problems is how to correct geometric distortion that originates in the habit of individual scanner.</p> <p>To use innumerable resources of printed binary topographic maps effectively, we propose an interactive interface and geometric correction algorithms, which uses peculiar coordinates information in individual map. The examples prove that the interactive interface using a cross cursor is useful and efficient for getting accurate input coordinates, and the proposed correction algorithm demonstrates high accuracy of corrected coordinates.</p>
