Abstract: The traditional method to draw contours has some disadvantages, such as adjacent contours are not well fitted and contours intersect and overlap each other. In order to overcome them, another simple but highly effective method is proposed in this paper. This method is based on mechanical model of spline function. The principle is that the vertical displacements of elastic lamella grids the elevation of land key points. Consequently we can use the finite element method to draw contours accurately. Through two examples, the practicability of this method is illuminated by using finite element general program ANSYS to draw contour. This method can be widely used in drawing contours of large scale relief maps.
