Topographic maps represent the locations of geographical features, such as hills and valleys. Topographic maps use contour lines to show different elevations on a map. A contour line is a type of isoline; in this case, a line of equal elevation. If you walk along a contour line you will not go uphill or downhill. Topographic maps translate three-dimensional land features into a two-dimensional (flat) map. You can look at a topographic map and quickly see where the hills, rivers, peaks, and valleys are. When you are navigating, a topographic map can show you where you are, what route to take, and which ways are dead ends. 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. .
