CONTOURING Figure 1 is a map of surveyed elevations. The dots represent data points of elevation above sea level, in feet. 6070 6056 6071 1. Draw the topographic contours, using a contour interval of 20 ft. You may choose to mark everv datum between two contours with the same-symbol or color and then group them together as you draw your contours. It is also recommended to use a pencil to draw in contours as even the best of us can make mistakes. 6041 6100 6120 6074 6115 6104 60586090 6152 6094 6130 6080 6 170 2. Describe the Iandform.
