- Many maps of land areas have series of curved lines, called contours, that represent the topography of the area. Such a map is called a topographic map. A contour is a horizontal curve that’s the locus of all points on the map with the same elevation (Figure 3-35).

Mathematically, a contour line is a curve in two dimensions on which the value of a function f (x, y) is a constant. Contour Lines and Intervals. Contour lines connect all the points on a map that have the same elevation and therefore reveal the location of hills, mountains, and valleys.
A topographic map is a type of map that adds a vertical dimension to an otherwise two-dimensional map defined by the north, south, east, and west compass directions. This third dimension on a topographic map is represented by contour lines , which represent a constant elevations above either sea level (either average sea level (a.s.l.) or mean sea level (m.s.l.)).
Topographic maps are maps that illustrate the topography (vertical shape, such as hills) of the mapped region. Geological maps are maps that illustrate the rock types, rock ages and other geological features of the mapped area. Every map has the following elements: Map area or data frame: the part of the map illustrating the map area itself;
