Instructions: Now it's time to practice drawing your own contour lines. The dots that you see (along with the corresponding numbers) are elevations above sea level. Two things to know before you begin: 1) what is the lowest elevation on the map, and 2) what is the contour interval. Refer to your mapping guides and videos provided in this course to help you get started. C.I. = 5 feet •5 .10 .4 • 15 21 ·17 io . 18 , z2 14 • 20 17
