Navigation Basics

topographical features

"Topographic Map. A map that presents the horizontal and vertical positions of the features represented; distinguished from a planimetric map by the addition of relief in measurable form."

An A-Z street map is not, therefore, a topographical map; it does not provide information about the shape of the land. This sort of information may be vital to navigation in otherwise featureless terrain.

contours

Contour lines are imaginary lines that join points that are equally high above sea-level (equal elevation or altitude). Occasionally there is a depression that is below sea-level.

Since maps are flat they cannot show the "shape" of the land they depict; contours provide that infomation.
