US Topo maps and scans of historic USGS topographic maps are also available as a part of The National Map.ĭata and products from The National Map can be used by government, industry, academia, as well as the public, in support of geologic mapping, natural hazard planning, natural resource conservation, emergency management, recreation, and many, many other applications. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level.

The National Map also serves as the data source for modern USGS topographic maps such as US Topos and OnDemand Topos. The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the Earths surface. In addition, The National Map provides continuously-updated, seamless datasets for recreational trails, roads, boundaries, structures, land cover, and imagery.
