Topographic maps of the Americas

Topographic Maps

A topographic map provides a detailed graphic representation of the natural and man-made features found on the earth鈥檚 surface. Topographic maps use contour lines to portray the shape and elevation of the terrain on a two-dimensional surface. Standard symbols and styles are used to identify general physical and cultural information such as mountains, lakes, vegetation, roads, and railways.

A topographic map is usually published as part of a larger map series, made up of two or more map sheets that combine to form the whole map for a defined area. Most countries of any significant size have several topographic map series, produced at different scales.
