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).
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.
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

Topographic Map. Topographic maps are detailed maps that represent the graphics features on the Earth's surface. The map uses contours lines to represent relief and other geographic features such as infrastructural development, water bodies, buildings, and other prominent features.
