PROBLEM TO BE SOLVED: To reduce labor for image preparation on an absolute coordinate system and to reduce the number of polygons while smoothly displaying a curved surface. SOLUTION: This system is provided with an instruction input means 3a capable of inputting the instruction of an operator, an execution editing means 3b for editing and preparing an image on a viewpoint coordinate system on the basis of instructed contents and a converting means 3c for converting the image expressed with the viewpoint coordinate system to the image of the absolute coordinate system. By providing a curvature calculating means 3e for calculating the curvature of a course provided on the absolute coordinate system and a control means 3g for determining the length of a polygon corresponding to the curvature of the course, the number of polygons is reduced while smoothly displaying the curved part of the course.
