Topographic maps are very detailed and require a variety of line use and color to properly express both natural and man-made features of an area. Because topographic maps express the elevation of an area contouring and an assortment of line segments are used. As shown in this topographic map of New York and in other topographic maps two-dimensional features are able to be shown on a map. This map of New York uses a color key to shown features. i.e. Blue = water, Green = foilage, Black square = building, etc.
