If the azimuthal equidistant projection map is centered about a point whose antipodal point lies on land and the map is extended to the maximum distance of 20,000 km (12,427 mi) the antipode point smears into a large circle. This is shown in the example of two maps centered about Los Angeles, and Taipei.
It contains the highest point in the contiguous 48 states, Mount Whitney (14,505 ft or 4,421 m). It is located at the boundary between California's Inyo and Tulare counties, just 84.6 mi or 136.2 km west-northwest of the lowest point in North America at the Badwater Basin in Death Valley National Park at 279 ft or 85 m below sea level.

Map of the Position of the U.S. Geographic Center of Area, Mean Center of Population, and Median Center of Population, 2020 (U.S. Census Bureau) [1] The geographic center of the United States is a point approximately 20 miles (32 km) north of Belle Fourche , South Dakota at 44°58′2.07622″N 103°46′17.60283″W / 44.9672433944°N ...
The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation. [5] In the United States, only Denali exceeds 6000 meters (19,685 feet) elevation.
Recent editions of these maps (those referenced to the North American datum of 1983, or NAD83) are compatible with USNG, and current editions also contain a standard USNG information box in the collar which identifies the GZD(s) (Grid Zone Designator(s) and the 100 km Grid Square ID(s) covering the area of the particular map. USNG can now be ...
The 40th parallel north is a circle of latitude that is 40 degrees north of the Earth's equatorial plane.It crosses Europe, the Mediterranean Sea, Asia, the Pacific Ocean, North America, and the Atlantic Ocean.
For example, a Mercator map printed in a book might have an equatorial width of 13.4 cm corresponding to a globe radius of 2.13 cm and an RF of approximately 1 / 300M (M is used as an abbreviation for 1,000,000 in writing an RF) whereas Mercator's original 1569 map has a width of 198 cm corresponding to a globe radius of 31.5 cm and an ...
