Streams, rivers, lakes, and various other important bodies of water. Mountains, forests, tree cover, and other large natural features. Trails, roads, railroads, and other major transportation infrastructure.
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.
What is a Topographic Map? Mapping is a crucial part of Earth science. 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.

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. Contour lines are lines that join places of equal height and make it possible to sho...
In order for topographic maps to be relevant and useful, the maps must have sufficient information on its size. The size of the map is derived by selecting a map scale that is neither large nor small. The map details are enhanced by the use of colors and symbols. The most commonly used USGC topographical map scale is 1:24,000, whereby, one inch on ...
The process of processing a topographic map is long and complex and may take up to five years. The process involves a team of surveyors, fact-checkers, engravers, and printers among other personnel. It involves photographing the area to be mapped which is done from the air and from different angles to provide a three-dimensional image that can be c...
Topographic maps are used for several purposes including traveling, recreation, and hiking. They are also used by governments and other organizations to assist with the creation of legal boundaries, mining, urban planning, and emergency management.

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.
topography:surface features both natural and cultural, collectively depicted on topographic maps. true north: direction of the northern rotational axis of the earth the North Pole. unclassified roads :roads for which the surface is unidentified.
