This site, provided by USGS, is an interactive map which enables users to zoom in and out of any area of the U.S. The map has tools that allow the user to layer it with different types of information, such as area boundaries, elevations, geographic names, geology, hydrography, land use/land cover, orthoimagery, structures, topography or transportation. Other tools included to ease navigation are options that allow users to view a location map, find a place, re-center, identify a place, find elevations, measure distances, and print and download maps that have been created. A help option is also included to aid the user with questions.
