First, we must identify the two contours that lie on either side of "P." In some cases the contours that we need are clearly labeled; however, in other instances, you will need to use the contour interval (1,000 feet, in this case) to "count" up or down from a labeled contour. Vertical
When the vertical dimension of your graph is different from the horizontal dimension on your map, you may end up with a graph that shows a vertical exaggerationand the features of the Earth represented by your topographic profile may be deformed such as in Figure 3.7.
