Topographic Map

      This is a topographic map; it is a large-scale map showing relief and man-made features of a portion of a land surface distinguished by portrayal of position, relation, size, shape, and elevation of the features. Unlike a planimetric map, it indicates both horizontal and vertical positions. Contour lines and shading are used in this example to represent the elevation of the land surface. At first glance, one can easily determine the shape of the land.
