Abstract: Problems of dot pattern technology include latitude/longitude information not being able to be acquired from a curvilinear solid. To read coordinate and/or code information from the vicinity of a line segment to acquire information associated with the line segment, it is necessary to define manually an area including the line segment to form the dot-pattern associated with the information in the area.

It becomes possible to create an information inputting medium that accurately defines the latitude/longitude and coordinate information on various line segments on the curvilinear solid, the map, the drawing, or the like.
