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...

The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the Earth's surface. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level.
Feb 10, 2021 · Topographic maps produced by NRCan conform to the National Topographic System (NTS) of Canada. They are available in two standard scales: 1:50 000 and 1:250 000. Each map in this system has a unique number, which is a combination of numbers and letters.
Topographic maps represent the Earth’s features accurately and to scale on a two-dimensional surface. Topographic maps are an excellent planning tool and guide and, at the same time, help make outdoor adventures enjoyable and safe.
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.)).
