The geographic information available includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures and land cover. The National Map is accessible via the Web, as products and services, and as downloadable data. Its uses range from recreation to scientific analysis to emergency ...
The National Elevation Dataset (NED) consists of high precision topography or ground surface elevation data (digital elevation model) for the United States. It was maintained by the USGS and all the data is in the public domain. Since the 3D Elevation Program came online, the NED was subsumed [1] into The National Map as one of its layers of ...
Enlargeable map of the 50 U.S. states by mean elevation. This list includes the topographic elevations of each of the 50 U.S. states, the District of Columbia, and the U.S. territories. [1] The elevation of a geographic area may be stated in several ways. These include: The maximum elevation of the area (high point); [a]
To be included on the list, a place needs to be an incorporated municipality (i.e. a city, town, or village) and it needs to be at an elevation of 3,000 feet (914 m) or higher. In the United States, settlements above 3,000 feet are found primarily on the High Plains, in the Rocky Mountains, and in Western North Carolina. However, since many ...
Currently, the best source for nationwide LiDAR availability from public sources is the United States Interagency Elevation Inventory (USIEI). [1] The USIEI is a collaborative effort of NOAA and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency, the Natural Resources Conservation Service, the US Army Corps of Engineers, and the National Park Service.

In the United States, where the primary national series is organized by a strict 7.5-minute grid, they are often called or quads or quadrangles. Topographic maps conventionally show topography, or land contours, by means of contour lines. Contour lines are curves that connect contiguous points of the same altitude .
