Examples for
Geodesy & Navigation
The field of geodesy studies the measurements and representation of the Earth. Wolfram|Alpha provides tools for examining this representation as well as examining other aspects of the world, such as its geogravitational and geomagnetic fields. Obtain coordinates, calculate distances and explore the distance to the horizon.
Find the coordinates of locations around the world or find what exists at a particular set of coordinates.
