What does the Contour Interval Note state?

The Contour Interval Note specifically highlights the vertical distance between adjacent contour lines on a map. This measurement is crucial for understanding the terrain's elevation changes, which can indicate how steep or flat an area is. Knowing the contour interval allows users to interpret the landscape accurately, assessing factors like grade and slope relevant for navigation, construction, and military operations. This information ultimately provides insight into how elevation varies in the mapped area, aiding in both planning and tactical decision-making.

Other options do not address the specific function of the contour interval note. The horizontal distance covered by the map pertains more to scale or mapping accuracy, while the overall scale of the map relates to the general representation of distance rather than elevation. Additionally, the elevation of the highest point offers specific data but does not reflect the consistent measurement needed for variation in terrain portrayed by contour lines.
