A contour refers to the outline or shape of an object or a particular area of land on a map. It is a line that connects points of equal elevation, also known as contour lines, which represent the variable height or depth of the landform being represented. These lines are typically drawn on topographic maps to depict the physical features of the terrain, including mountains, valleys, and other changes in elevation. Contour lines help to illustrate the three-dimensional nature of the landscape on a two-dimensional map, making it easier to visualize the shape and steepness of the land.
