| Abstract: | t This paper presents a method for fair drawing geologic maps by computer.The procedures begin with graphic digitizing input of a manual sketch map(contour map or sedimentary facies map).The curves are then smoothed and the graphic can be displayed on a screen or output with a plotter.The maps drawn by computer are accurate,nice looking and easy in scaling.This method may substitute manual drawing and has been used in many cases. |
