WebAug 30, 2024 · To calculate the vertical exaggeration in the topographic profile shown in Figure 3.6 we divide the horizontal scale by the vertical scale: ( 1000 f t 1 i n c h) ( 100 f t i n c h) = 10. Therefore the topographic profile in Figure 3.6 represents a profile of the map surface (along the A-B line) that has been vertically exaggerated by 10 times ... WebA portion of a topographic map, including the contour interval label. On topographic maps, each contour line connects points at the same elevation. The contour interval is the difference in elevation between adjacent contour lines. The elevation for each contour line is sometimes marked on the line. To avoid clutter, not every contour is labeled.
