Abstract
A topographic map accurately represents the natural and manmade features of the land. USGS topographic maps are compiled to National Map Accuracy Standards using modern mapping techniques. The shape and elevation of the terrain are portrayed by contour lines and specific vegetation are portrayed by map sumbols and colors. This is a 7.5 minute series.
