Topographic Maps and Countours - Illinois Institute of Technology

Contour Map Generation •Example: •Contours are to be placed every ten feet. d = 300 feet • There are to be three contour lines on this interval. • Divide 300 feet by 3 to get one contour every 100 feet. • Mark four points (two on the endpoints, and two between) and draw the contours.
