Topographic Map


A topographic map is similar to a planimteric map, however, elevation and depth are included. Contour lines and different colors are used to distinguish between the topography of different areas. The detail allows for easy analysis of the land being mapped. Topographic maps are most commonly used as GPS devices. Topographic maps are sometimes referred to as contour maps. The picture above is a historic topographic map. The contour lines and different colors seen in the map distinguish the different elevations of the location presented.
