✨ What Do Topographic Maps Show

Topographic Contours. 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). Topographic maps show a wide range of human and physical features of the Earth. They are very detailed and are often produced on large sheets of paper. The First Topographic Map A topographic map is a detailed and accurate illustration of man-made and natural features on the ground such as roads, railways, power transmission lines, contours, elevations, rivers, lakes and geographical names. The topographic map is a two-dimensional representation of the Earth’s three-dimensional landscape. WZwQYb.
