Topographic Map


Topographic maps are considered to be a large-scale maps showing relief. These types of map use contour lines to portray the shape and elevation of land. They also capture 3-dimensional aspect of terrain on two-dimensional surface. Contours are imaginary lines that join points of equal elevation on the surface of the land above or below a reference surface as mean sea level. This particular map can be considered a topographic map because it shows the different elevations with shaded relief. Due to this maps large scale and quantitative representation of relief is it able to qualify as a topographic map.
