A topographical map is primarily used to represent large-scale detail and elevation changes in the landscape. These maps depict the physical features of the terrain, showing both natural and artificial landmarks, including mountains, valleys, hills, and flat areas. The use of contour lines is a hallmark of topographical maps, as they indicate elevation through lines that connect points of equal height. This allows users to understand the steepness of slopes, the height of peaks, and the overall relief of the area.

In contrast, the other options focus on specific elements that are not the primary function of a topographical map. For example, while a map could potentially show vegetation or political boundaries, it would not primarily function to illustrate these features. Similarly, although water bodies and their depths can be represented on some types of maps, they are not the main emphasis of topographical maps, which focus on terrain and elevation instead.
